Type

getParent

public NodeInfo getParent()

Find the parent node of this node.

Specified by:

getParent in interface NodeInfo

Overrides:

getParent in class TinyNodeImpl

Returns:

The Node object describing the containing element or root node.

getRoot

public NodeInfo getRoot()

Get the root node

Specified by:

getRoot in interface NodeInfo

Overrides:

getRoot in class TinyNodeImpl

Returns:

the NodeInfo that is the root of the tree - not necessarily a document node

getDocumentRoot

generateId

public void generateId(FastStringBuffer buffer)

Get a character string that uniquely identifies this node

Parameters:

atomize

public Value<? extends AtomicValue> atomize()
                                     throws XPathException

Get the typed value. The result of this method will always be consistent with the method Item.getTypedValue(). However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.

Specified by:

atomize in interface NodeInfo

Returns:

the typed value. This will either be a single AtomicValue or a Value whose items are atomic values.

Throws:

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

Since:

8.5

getTypedValue

public SequenceIterator<? extends AtomicValue> getTypedValue()
                                                      throws XPathException

Get the typed value of the item.

For a node, this is the typed value as defined in the XPath 2.0 data model. Since a node may have a list-valued data type, the typed value is in general a sequence, and it is returned in the form of a SequenceIterator.

If the node has not been validated against a schema, the typed value will be the same as the string value, either as an instance of xs:string or as an instance of xs:untypedAtomic, depending on the node kind.

For an atomic value, this method returns an iterator over a singleton sequence containing the atomic value itself.

Specified by:

getTypedValue in interface Item<NodeInfo>

Returns:

an iterator over the items in the typed value of the node or atomic value. The items returned by this iterator will always be atomic values.

Throws:

XPathException - where no typed value is available, for example in the case of an element with complex content

Since:

8.4

selectID

public NodeInfo selectID(String id,
                         boolean getParent)

Get the element with a given ID.

Specified by:

selectID in interface DocumentInfo

Parameters:

id - The unique ID of the required element, previously registered using registerID()

getParent - true if the required element is the parent of the element of type ID

Returns:

The NodeInfo (always an Element) for the given ID if one has been registered, otherwise null.

getUnparsedEntityNames

public Iterator<String> getUnparsedEntityNames()

Get the list of unparsed entities defined in this document

Specified by:

getUnparsedEntityNames in interface DocumentInfo

Returns:

an Iterator, whose items are of type String, containing the names of all unparsed entities defined in this document. If there are no unparsed entities or if the information is not available then an empty iterator is returned

getUnparsedEntity

public String[] getUnparsedEntity(String name)

Get the unparsed entity with a given nameID if there is one, or null if not. If the entity does not exist, return null.

Specified by:

getUnparsedEntity in interface DocumentInfo

Parameters:

name - the name of the entity

Returns:

if the entity exists, return an array of two Strings, the first holding the system ID of the entity, the second holding the public

getTypeAnnotation

public int getTypeAnnotation()

Get the type annotation of this node, if any.

Specified by:

getTypeAnnotation in interface NodeInfo

Overrides:

getTypeAnnotation in class TinyNodeImpl

Returns:

XS_UNTYPED if no validation has been done, XS_ANY_TYPE if the document has been validated

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

Overrides:

getSchemaType in class TinyNodeImpl

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

copy

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

Copy this node to a given outputter

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-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information

Throws:

XPathException - if any downstream error occurs

showSize

public void showSize()

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 TinyNodeImpl

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.

setUserData

public void setUserData(String key,
                        Object value)

Set user data on the document node. The user data can be retrieved subsequently using getUserData(java.lang.String)

Specified by:

setUserData in interface DocumentInfo

Parameters:

key - A string giving the name of the property to be set. Clients are responsible for choosing a key that is likely to be unique. Must not be null. Keys used internally by Saxon are prefixed "saxon:".

value - The value to be set for the property. May be null, which effectively removes the existing value for the property.

getUserData

public Object getUserData(String key)

Get user data held in the document node. This retrieves properties previously set using setUserData(java.lang.String, java.lang.Object)

Specified by:

getUserData in interface DocumentInfo

Parameters:

key - A string giving the name of the property to be retrieved.

Returns:

the value of the property, or null if the property has not been defined.
