Constructor Detail

TinyDocumentImpl

public TinyDocumentImpl(TinyTree tree)

Method Detail

getTree

public TinyTree getTree()

Get the tree containing this node

Overrides:

getTree in class TinyNodeImpl

Returns:

the TinyTree. Note that this may also contain other unrelated trees

getRootNode

public NodeInfo getRootNode()

Get the NodeInfo object representing the document node at the root of the tree

Returns:

the document node

getConfiguration

public Configuration getConfiguration()

Get the configuration previously set using setConfiguration

Specified by:

getConfiguration in interface FingerprintedNode

Specified by:

getConfiguration in interface NodeInfo

Overrides:

getConfiguration in class TinyNodeImpl

Returns:

the Configuration to which the tree belongs

setSystemId

public void setSystemId(String uri)

Set the system id of this node

Specified by:

setSystemId in interface Source

Overrides:

setSystemId in class TinyNodeImpl

getSystemId

public String getSystemId()

Get the system id of this root node

Specified by:

getSystemId in interface Source

Specified by:

getSystemId in interface SourceLocator

Specified by:

getSystemId in interface Location

Specified by:

getSystemId in interface NodeInfo

Specified by:

getSystemId in interface Locator

Overrides:

getSystemId in class TinyNodeImpl

Returns:

the System Identifier of the entity in the source document containing the node, or null if not known or not applicable.

setBaseURI

public void setBaseURI(String uri)

Set the base URI of this document node

Parameters:

uri - the base URI

getBaseURI

public String getBaseURI()

Get the base URI of this root node.

Specified by:

getBaseURI in interface NodeInfo

Overrides:

getBaseURI in class TinyNodeImpl

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 the line number of this root node.

Specified by:

getLineNumber in interface SourceLocator

Specified by:

getLineNumber in interface Location

Specified by:

getLineNumber in interface NodeInfo

Specified by:

getLineNumber in interface Locator

Overrides:

getLineNumber in class TinyNodeImpl

Returns:

0 always

isTyped

public boolean isTyped()

Ask whether the document contains any nodes whose type annotation is anything other than UNTYPED

Returns:

true if the document contains elements whose type is other than UNTYPED

getNodeKind

public final int getNodeKind()

Return the type of node.

Returns:

Type.DOCUMENT (always)

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

generateId

public void generateId(FastStringBuffer buffer)

Get a character string that uniquely identifies this node

Specified by:

generateId in interface NodeInfo

Overrides:

generateId in class TinyNodeImpl

Parameters:

buffer - to contain an identifier based on the document number

atomize

public AtomicSequence atomize()
                       throws XPathException

Get the typed value.

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

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,
        Location locationId)
          throws XPathException

Copy this node to a given outputter

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

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.
