Class DocumentWrapper

java.lang.Object
  net.sf.saxon.option.xom.NodeWrapper
      net.sf.saxon.option.xom.DocumentWrapper

All Implemented Interfaces:

Source, PullEvent, DocumentInfo, Item, NodeInfo, ValueRepresentation, SiblingCountingNode, VirtualNode

public class DocumentWrapper
extends NodeWrapper
implements DocumentInfo

The root node of an XPath tree. (Or equivalently, the tree itself).

This class is used not only for a document, but also for the root of a document-less tree fragment.

Constructor Detail

DocumentWrapper

public DocumentWrapper(Node root,
                       String baseURI,
                       Configuration config)

Create a Saxon wrapper for a XOM root node

Parameters:

root - The XOM root node

baseURI - The base URI for all the nodes in the tree

config - The configuration which defines the name pool used for all names in this tree

Method Detail

wrap

public NodeInfo wrap(Node node)

Wrap a node in the XOM document.

Parameters:

node - The node to be wrapped. This must be a node in the same document (the system does not check for this).

Returns:

the wrapping NodeInfo object

setConfiguration

public void setConfiguration(Configuration config)

Set the configuration, which defines the name pool used for all names in this document. This is always called after a new document has been created. The implementation must register the name pool with the document, so that it can be retrieved using getNamePool(). It must also call NamePool.allocateDocumentNumber(), and return the relevant document number when getDocumentNumber() is subsequently called.

Parameters:

config - The configuration to be used

getConfiguration

public Configuration getConfiguration()

Get the configuration previously set using setConfiguration

Specified by:

getConfiguration in interface NodeInfo

Overrides:

getConfiguration in class NodeWrapper

Returns:

the Configuration

getNamePool

public NamePool getNamePool()

Get the name pool used for the names in this document

Specified by:

getNamePool in interface NodeInfo

Overrides:

getNamePool in class NodeWrapper

Returns:

the name pool in which all the names used in this document are registered

getDocumentNumber

public long getDocumentNumber()

Get the unique document number for this document (the number is unique for all documents within a NamePool)

Specified by:

getDocumentNumber in interface NodeInfo

Overrides:

getDocumentNumber in class NodeWrapper

Returns:

the unique number identifying this document within the name pool

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).

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:

null: XOM does not provide access to unparsed entities

getTypeAnnotation

public int getTypeAnnotation()

Get the type annotation of this node, if any. Returns -1 for kinds of nodes that have no annotation, and for elements annotated as untyped, and attributes annotated as untypedAtomic.

Specified by:

getTypeAnnotation in interface NodeInfo

Overrides:

getTypeAnnotation in class NodeWrapper

Returns:

the type annotation of the node.

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.
