      com.saxonica.pull.UnconstructedDocument

All Implemented Interfaces:

Source, PullEvent, DocumentInfo, Item, NodeInfo, ValueRepresentation

public class UnconstructedDocument
extends UnconstructedParent
implements DocumentInfo

A document node whose construction is deferred.

(TODO) NOTE: this class is an exception to the general rule that for document nodes, node identity implies object identity

Constructor Detail

UnconstructedDocument

public UnconstructedDocument(DocumentInstr instruction,
                             XPathContext context)

Create an unconstructed (pending) document node

Parameters:

instruction - the instruction responsible for creating the node

context - the XPath dynamic context

Method Detail

getNameCode

public int getNameCode()

Get name code. The name code is a coded form of the node name: two nodes with the same name code have the same namespace URI, the same local name, and the same prefix. By masking the name code with &0xfffff, you get a fingerprint: two nodes with the same fingerprint have the same local name and namespace URI.

Specified by:

getNameCode in interface NodeInfo

Returns:

an integer name code, which may be used to obtain the actual node name from the name pool

See Also:

allocate, getFingerprint

getNodeKind

public int getNodeKind()

Description copied from interface: NodeInfo

Get the kind of node. This will be a value such as Type.ELEMENT or Type.ATTRIBUTE. There are seven kinds of node: documents, elements, attributes, text, comments, processing-instructions, and namespaces.

Specified by:

getNodeKind in interface NodeInfo

Returns:

an integer identifying the kind of node. These integer values are the same as those used in the DOM

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. A fingerprint of -1 should be returned for a node with no name.

Specified by:

getFingerprint in interface NodeInfo

Overrides:

getFingerprint in class UnconstructedParent

Returns:

an integer fingerprint; two nodes with the same fingerprint have the same expanded QName

getLocalPart

public 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

Overrides:

getLocalPart in class UnconstructedParent

Returns:

the local part of the name. For an unnamed node, returns "". Unlike the DOM interface, this returns the full name in the case of a non-namespaced name.

getURI

public String getURI()

Get the URI part of the name of this node. This is the URI corresponding to the prefix, or the URI of the default namespace if appropriate.

Specified by:

getURI in interface NodeInfo

Overrides:

getURI in class UnconstructedParent

Returns:

The URI of the namespace of this node. For an unnamed node, or for a node with an empty prefix, return an empty string.

getDisplayName

public 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.

Specified by:

getDisplayName in interface NodeInfo

Overrides:

getDisplayName in class UnconstructedParent

Returns:

The display name of this node. For a node with no name, return an empty string.

getPrefix

public String getPrefix()

Get the prefix of the name of the node. This is defined only for elements and attributes. If the node has no prefix, or for other kinds of node, return a zero-length string.

Specified by:

getPrefix in interface NodeInfo

Overrides:

getPrefix in class UnconstructedParent

Returns:

The prefix of the name of the node.

getDocumentRoot

public DocumentInfo getDocumentRoot()

Get the root node, if it is a document node.

Specified by:

getDocumentRoot in interface NodeInfo

Overrides:

getDocumentRoot in class UnconstructedParent

Returns:

the DocumentInfo representing the containing document. If this node is part of a tree that does not have a document node as its root, return null.

selectID

public NodeInfo selectID(String id,
                         boolean getParent)

Get the element with a given ID, if any

Specified by:

selectID in interface DocumentInfo

Parameters:

id - the required ID value

getParent -

Returns:

the element with the given ID, or null if there is no such ID present (or if the parser has not notified attributes as being of type ID)

Since:

8.4

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 name

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 ID if there is one, or null if not. If the entity does not exist, the method returns null. Applications should be written on the assumption that this array may be extended in the future to provide additional information.
