Class DocumentWrapper

java.lang.Object

net.sf.saxon.option.dom4j.NodeWrapper

net.sf.saxon.option.dom4j.DocumentWrapper

All Implemented Interfaces:

javax.xml.transform.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 should have been named Root; it is used not only for the root of a document, but also for the root of a result tree fragment, which is not constrained to contain a single top-level element.

Constructor Detail

DocumentWrapper

public DocumentWrapper(org.dom4j.Document doc,
               java.lang.String baseURI,
               Configuration config)

Create a Saxon wrapper for a dom4j document

Parameters:

doc - The dom4j document

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

config - The Saxon configuration

Method Detail

wrap

public NodeInfo wrap(java.lang.Object node)

Wrap a node in the dom4j 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

getDocumentNumber

public long getDocumentNumber()

Get the unique document number

Specified by:

getDocumentNumber in interface NodeInfo

Overrides:

getDocumentNumber in class NodeWrapper

Returns:

the document number of the document containing this node

selectID

public NodeInfo selectID(java.lang.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:

null: dom4j does not provide any information about attribute types.

getUnparsedEntityNames

public java.util.Iterator<java.lang.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 java.lang.String[] getUnparsedEntity(java.lang.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: dom4j does not provide access to unparsed entities

getConfiguration

public Configuration getConfiguration()

Get the configuration previously set using setConfiguration (or the default configuraton allocated automatically)

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 NamePool

setConfiguration

public void setConfiguration(Configuration config)

Set the configuration (containing the name pool used for all names in this document). Calling this method allocates a unique number to the document (unique within the Configuration); this will form the basis for testing node identity

Parameters:

config - the configuration

getTypeAnnotation

public int getTypeAnnotation()

Get the type annotation. Always XS_UNTYPED.

Specified by:

getTypeAnnotation in interface NodeInfo

Overrides:

getTypeAnnotation in class NodeWrapper

Returns:

UNTYPED or UNTYPED_ATOMIC

setUserData

public void setUserData(java.lang.String key,
               java.lang.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 java.lang.Object getUserData(java.lang.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.
