Constructor Detail

XOMDocumentWrapper

public XOMDocumentWrapper(Node root,
                  Configuration config)

Create a Saxon wrapper for a XOM root node

Parameters:

root - The XOM root node

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

Method Detail

getRootNode

public NodeInfo getRootNode()

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

Specified by:

getRootNode in interface TreeInfo

Returns:

the document node

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

Specified by:

getConfiguration in interface TreeInfo

Overrides:

getConfiguration in class XOMNodeWrapper

Returns:

the Configuration to which the tree belongs

getNamePool

public NamePool getNamePool()

Get the name pool used for the names in this document

Overrides:

getNamePool in class XOMNodeWrapper

Returns:

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

setSystemId

public void setSystemId(String uri)

Description copied from class: AbstractNodeWrapper

Set the system ID. Required because NodeInfo implements the JAXP Source interface

Specified by:

setSystemId in interface Source

Overrides:

setSystemId in class AbstractNodeWrapper

Parameters:

uri - the system ID.

isTyped

public boolean isTyped()

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

Specified by:

isTyped in interface TreeInfo

Returns:

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

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 TreeInfo

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 TreeInfo

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 TreeInfo

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 TreeInfo

Parameters:

name - the name of the entity

Returns:

null: XOM does not provide access to unparsed entities

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 XOMNodeWrapper

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.

9.4

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 TreeInfo

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 TreeInfo

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.
