All Implemented Interfaces:

javax.xml.transform.Source, javax.xml.transform.SourceLocator, Location, Item, MutableNodeInfo, NodeInfo, Sequence, TreeInfo, org.xml.sax.Locator

public final class Orphan
extends GenericTreeInfo
implements MutableNodeInfo

A node (implementing the NodeInfo interface) representing an attribute, text node, comment, processing instruction, or namespace that has no parent (and of course no children). Exceptionally it is also used (during whitespace stripping) to represent a standalone element.

In general this class does not impose constraints defined in the data model: that is the responsibility of the client. For example, the class does not prevent you from creating a comment or text node that has a name or a non-trivial type annotation.

See Also:

Type

getFingerprint

public int getFingerprint()

Get fingerprint. The fingerprint is a coded form of the expanded name of the node: two nodes with the same name code have the same namespace URI and the same local name. The fingerprint contains no information about the namespace prefix. For a name in the null namespace, the fingerprint is the same as the name code.

Specified by:

getFingerprint in interface NodeInfo

Returns:

an integer fingerprint; two nodes with the same fingerprint have the same expanded QName. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.

Throws:

java.lang.UnsupportedOperationException - if this kind of node does not hold namepool fingerprints (specifically, if hasFingerprint() returns false).

Since:

8.4 (moved into FingerprintedNode at some stage; then back into NodeInfo at 9.8).

hasFingerprint

public boolean hasFingerprint()

Ask whether this NodeInfo implementation holds a fingerprint identifying the name of the node in the NamePool. If the answer is true, then the getFingerprint() method must return the fingerprint of the node. If the answer is false, then the getFingerprint() method should throw an UnsupportedOperationException. In the case of unnamed nodes such as text nodes, the result can be either true (in which case getFingerprint() should return -1) or false (in which case getFingerprint may throw an exception).

Specified by:

hasFingerprint in interface NodeInfo

Returns:

true if the implementation of this node provides fingerprints.

Since:

9.8; previously Saxon relied on using FingerprintedNode as a marker interface.

atomize

public AtomicSequence atomize()
                       throws XPathException

Get the typed value.

Specified by:

atomize in interface Item

Specified by:

atomize in interface NodeInfo

Returns:

the typed value.

Throws:

XPathException - if the node has no typed value, for example if it is an element node with element-only content

Since:

8.5

getSchemaType

public SchemaType getSchemaType()

Get the type annotation of this node, if any. The type annotation is represented as SchemaType object.

Types derived from a DTD are not reflected in the result of this method.

Specified by:

getSchemaType in interface NodeInfo

Returns:

For element and attribute nodes: the type annotation derived from schema validation (defaulting to xs:untyped and xs:untypedAtomic in the absence of schema validation). For comments, text nodes, processing instructions, and namespaces: null. For document nodes, either xs:untyped if the document has not been validated, or xs:anyType if it has.

Since:

9.4

isSameNodeInfo

public boolean isSameNodeInfo(NodeInfo other)

Determine whether this is the same node as another node.
Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)

Specified by:

isSameNodeInfo in interface NodeInfo

Parameters:

other - the node to be compared with this node

Returns:

true if this Node object and the supplied Node object represent the same node in the tree.

equals

public boolean equals(java.lang.Object other)

The equals() method compares nodes for identity. It is defined to give the same result as isSameNodeInfo().

Specified by:

equals in interface NodeInfo

Overrides:

equals in class java.lang.Object

Parameters:

other - the node to be compared with this node

Returns:

true if this NodeInfo object and the supplied NodeInfo object represent the same node in the tree.

Since:

8.7 Previously, the effect of the equals() method was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics. It is safer to use isSameNodeInfo() for this reason. The equals() method has been defined because it is useful in contexts such as a Java Set or HashMap.

hashCode

public int hashCode()

The hashCode() method obeys the contract for hashCode(): that is, if two objects are equal (represent the same node) then they must have the same hashCode()

Specified by:

hashCode in interface NodeInfo

Overrides:

hashCode in class java.lang.Object

Since:

8.7 Previously, the effect of the equals() and hashCode() methods was not defined. Callers should therefore be aware that third party implementations of the NodeInfo interface may not implement the correct semantics.

getBaseURI

public java.lang.String getBaseURI()

Get the Base URI for the node, that is, the URI used for resolving a relative URI contained in the node. This will be the same as the System ID unless xml:base has been used.

Specified by:

getBaseURI in interface NodeInfo

Returns:

the base URI of the node. This may be null if the base URI is unknown, including the case where the node has no parent.

getLineNumber

public int getLineNumber()

Get line number

Specified by:

getLineNumber in interface javax.xml.transform.SourceLocator

Specified by:

getLineNumber in interface Location

Specified by:

getLineNumber in interface NodeInfo

Specified by:

getLineNumber in interface org.xml.sax.Locator

Returns:

the line number of the node in its original source document; or -1 if not available

getColumnNumber

public int getColumnNumber()

Get column number

Specified by:

getColumnNumber in interface javax.xml.transform.SourceLocator

Specified by:

getColumnNumber in interface Location

Specified by:

getColumnNumber in interface NodeInfo

Specified by:

getColumnNumber in interface org.xml.sax.Locator

Returns:

the column number of the node in its original source document; or -1 if not available

saveLocation

public Location saveLocation()

Get an immutable copy of this Location object. By default Location objects may be mutable, so they should not be saved for later use. The result of this operation holds the same location information, but in an immutable form.

Specified by:

saveLocation in interface Location

compareOrder

public int compareOrder(NodeInfo other)

Determine the relative position of this node and another node, in document order. The other node will always be in the same document.

Specified by:

compareOrder in interface NodeInfo

Parameters:

other - The other node, whose position is to be compared with this node

Returns:

-1 if this node precedes the other node, +1 if it follows the other node, or 0 if they are the same node. (In this case, isSameNode() will always return true, and the two nodes will produce the same result for generateId())

comparePosition

public int comparePosition(NodeInfo other)

Determine the relative position of this node and another node, in document order, distinguishing whether the first node is a preceding, following, descendant, ancestor, or the same node as the second.

The other node must always be in the same tree; the effect of calling this method when the two nodes are in different trees is undefined. If either node is a namespace or attribute node, the method should throw UnsupportedOperationException.

Specified by:

comparePosition in interface NodeInfo

Parameters:

other - The other node, whose position is to be compared with this node

Returns:

AxisInfo.PRECEDING if this node is on the preceding axis of the other node; AxisInfo.FOLLOWING if it is on the following axis; AxisInfo.ANCESTOR if the first node is an ancestor of the second; AxisInfo.DESCENDANT if the first is a descendant of the second; AxisInfo.SELF if they are the same node.

Throws:

java.lang.UnsupportedOperationException - if either node is an attribute or namespace

Since:

9.5

getStringValue

public java.lang.String getStringValue()

Return the string value of the node.

Specified by:

getStringValue in interface NodeInfo

Returns:

the string value of the node

See Also:

Item.getStringValueCS()

getStringValueCS

public java.lang.CharSequence getStringValueCS()

Get the value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String.

Specified by:

getStringValueCS in interface Item

Returns:

the string value of the item

See Also:

Item.getStringValue()

getLocalPart

public java.lang.String getLocalPart()

Get the local part of the name of this node. This is the name after the ":" if any.

Specified by:

getLocalPart in interface NodeInfo

Returns:

the local part of the name. For an unnamed node, returns "".

Specified by:

getPrefix in interface NodeInfo

Returns:

The prefix of the name of the node.

getDisplayName

public java.lang.String getDisplayName()

Get the display name of this node. For elements and attributes this is [prefix:]localname. For unnamed nodes, it is an empty string.

the attribute value if it exists, or null if it does not exist. Always returns null if this node is not an element.

Since:

9.4

getRoot

public NodeInfo getRoot()

Get the root node of this tree (not necessarily a document node). Always returns this node in the case of an Orphan node.

Specified by:

getRoot in interface NodeInfo

Returns:

the NodeInfo representing the top-level ancestor of this node. This will not necessarily be a document node. If this node has no parent, then the method returns this node.

hasChildNodes

public boolean hasChildNodes()

Determine whether the node has any children.

Specified by:

hasChildNodes in interface NodeInfo

Returns:

false - an orphan node never has any children

generateId

public void generateId(FastStringBuffer buffer)

Get a character string that uniquely identifies this node. Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)

Specified by:

generateId in interface NodeInfo

Parameters:

buffer - a buffer, into which will be placed a string that uniquely identifies this node, within this document. The calling code prepends information to make the result unique across all documents.

copy

public void copy(Receiver out,
                 int copyOptions,
                 Location locationId)
          throws XPathException

Copy this node to a given outputter (deep copy)

Specified by:

copy in interface NodeInfo

Parameters:

out - the Receiver to which the node should be copied. It is the caller's responsibility to ensure that this Receiver is open before the method is called (or that it is self-opening), and that it is closed after use.

copyOptions - a selection of the options defined in CopyOptions

locationId - If non-null, identifies the location of the instruction that requested this copy. If zero, indicates that the location information is not available

Throws:

XPathException - if any downstream error occurs

getDeclaredNamespaces

public NamespaceBinding[] getDeclaredNamespaces(NamespaceBinding[] buffer)

Get all namespace undeclarations and undeclarations defined on this element.

Specified by:

getDeclaredNamespaces in interface NodeInfo

Parameters:

buffer - If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.

Returns:

An array of integers representing the namespace declarations and undeclarations present on this element. For a node other than an element, return null. Otherwise, the returned array is a sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The top half word of each namespace code represents the prefix, the bottom half represents the URI. If the bottom half is zero, then this is a namespace undeclaration rather than a declaration. The XML namespace is never included in the list. If the supplied array is larger than required, then the first unused entry will be set to -1.

For a node other than an element, the method returns null.

                           boolean inherit)

Insert copies of a sequence of nodes as children of this node.

This method takes no action unless the target node is a document node or element node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.

The supplied nodes will be copied to form the new children. Adjacent text nodes will be merged, and zero-length text nodes removed.

Specified by:

insertChildren in interface MutableNodeInfo

Parameters:

source - the nodes to be inserted

atStart - true if the new nodes are to be inserted before existing children; false if they are

inherit - true if the insert nodes are to inherit the namespaces of their new parent; false if such namespaces are to be undeclared

insertSiblings

public void insertSiblings(NodeInfo[] source,
                           boolean before,
                           boolean inherit)

Insert copies of a sequence of nodes as siblings of this node.

This method takes no action unless the target node is an element, text node, comment, or processing instruction, and one that has a parent node. It also takes no action in respect of any supplied nodes that are not elements, text nodes, comments, or processing instructions.

The supplied nodes must use the same data model implementation as the tree into which they will be inserted.

Specified by:

insertSiblings in interface MutableNodeInfo

Parameters:

source - the nodes to be inserted

before - true if the new nodes are to be inserted before the target node; false if they are

inherit - true if the insert nodes are to inherit the namespaces of their new parent; false if such namespaces are to be undeclared

removeAttribute

public void removeAttribute(NodeInfo attribute)

Remove an attribute from this element node

If this node is not an element, or if it has no attribute with the specified name, this method takes no action.

The attribute node itself is not modified in any way.

Specified by:

removeAttribute in interface MutableNodeInfo

Parameters:

attribute - the attribute node to be removed

addAttribute

public void addAttribute(NodeName nameCode,
                         SimpleType attType,
                         java.lang.CharSequence value,
                         int properties)

Add an attribute to this element node.

If this node is not an element, or if the supplied node is not an attribute, the method takes no action. If the element already has an attribute with this name, the existing attribute is replaced.

Specified by:

addAttribute in interface MutableNodeInfo

Parameters:

nameCode - the name of the new attribute

attType - the type annotation of the new attribute

value - the string value of the new attribute

properties - properties including IS_ID and IS_IDREF properties

delete

public void delete()

Delete this node (that is, detach it from its parent).

If this node has preceding and following siblings that are both text nodes, the two text nodes will be joined into a single text node (the identity of this node with respect to its predecessors is undefined).

Specified by:

delete in interface MutableNodeInfo

isDeleted

public boolean isDeleted()

Test whether this MutableNodeInfo object represents a node that has been deleted. Generally, such a node is unusable, and any attempt to use it will result in an exception being thrown

Specified by:

isDeleted in interface MutableNodeInfo

Returns:

true if this node has been deleted

replace

public void replace(NodeInfo[] replacement,
                    boolean inherit)

Replace this node with a given sequence of nodes

Specified by:

replace in interface MutableNodeInfo

Parameters:

replacement - the replacement nodes

inherit - true if the replacement nodes are to inherit the namespaces of their new parent; false if such namespaces are to be undeclared

Throws:

java.lang.IllegalArgumentException - if any of the replacement nodes is of the wrong kind. When replacing a child node, the replacement nodes must all be elements, text, comment, or PI nodes; when replacing an attribute, the replacement nodes must all be attributes.

java.lang.IllegalStateException - if this node is deleted or if it has no parent node.

replaceStringValue

public void replaceStringValue(java.lang.CharSequence stringValue)

Replace the string-value of this node. If applied to an element or document node, this causes all existing children to be deleted, and replaced with a new text node whose string value is the value supplied. The caller is responsible for checking that the value is valid, for example that comments do not contain a double hyphen; the implementation is not required to check for such conditions.

Specified by:

replaceStringValue in interface MutableNodeInfo

Parameters:

stringValue - the new string value

rename

public void rename(NodeName newNameCode)

Rename this node.

This call has no effect if applied to a nameless node, such as a text node or comment.

If necessary, a new namespace binding will be added to the target element, or to the element parent of the target attribute

Specified by:

rename in interface MutableNodeInfo

Parameters:

newNameCode - the namecode of the new name in the name pool

Throws:

java.lang.IllegalArgumentException - if the new name code is not present in the name pool, or if it has a (prefix, uri) pair in which the prefix is the same as that of an existing in-scope namespace binding and the uri is different from that namespace binding.

addNamespace

public void addNamespace(NamespaceBinding nscode,
                         boolean inherit)

Add a namespace binding (that is, a namespace node) to this element. This call has no effect if applied to a node other than an element.

Specified by:

addNamespace in interface MutableNodeInfo

Parameters:

nscode - The namespace code representing the (prefix, uri) pair of the namespace binding to be added. If the target element already has a namespace binding with this (prefix, uri) pair, the call has no effect. If the target element currently has a namespace binding with this prefix and a different URI, an exception is raised.

inherit - If true, the new namespace binding will be inherited by any children of the target element that do not already have a namespace binding for the specified prefix, recursively. If false, the new namespace binding will not be inherited.

Throws:

java.lang.IllegalArgumentException - if the namespace code is not present in the namepool, or if the target element already has a namespace binding for this prefix

removeTypeAnnotation

public void removeTypeAnnotation()

Remove type information from this node (and its ancestors, recursively). This method implements the upd:removeType() primitive defined in the XQuery Update specification. (Note: the caller is responsible for updating the set of nodes marked for revalidation)

Specified by:

removeTypeAnnotation in interface MutableNodeInfo

newBuilder

public Builder newBuilder()

Get a Builder suitable for building nodes that can be attached to this document. This implementation always throws an exception: the method should only be called on a document or element node when creating new children.

Specified by:

newBuilder in interface MutableNodeInfo

Returns:

a new Builder that constructs nodes using the same object model implementation as this one, suitable for attachment to this tree
