Constructor Detail

DocumentWrapper

public DocumentWrapper(org.w3c.dom.Node doc,
               java.lang.String baseURI,
               Configuration config)

Wrap a DOM Document or DocumentFragment node

Parameters:

doc - a DOM Document or DocumentFragment node

baseURI - the base URI of the document

config - the Saxon configuration

Method Detail

wrap

public NodeWrapper wrap(org.w3c.dom.Node node)

Create a wrapper for a node in this document

Parameters:

node - the DOM node to be wrapped. This must be a node within the document wrapped by this DocumentWrapper

Throws:

java.lang.IllegalArgumentException - if the node is not a descendant of the Document node wrapped by this DocumentWrapper

setConfiguration

public void setConfiguration(Configuration config)

Set the Configuration that contains this document

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 NamePool

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:

a NodeInfo representing the element with the given ID, or null if there is no such element. This implementation does not necessarily conform to the rule that if an invalid document contains two elements with the same ID, the one that comes last should be returned.

isSameNodeInfo

public boolean isSameNodeInfo(NodeInfo other)

Determine whether this is the same node as another node.
Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)

Specified by:

isSameNodeInfo in interface NodeInfo

Overrides:

isSameNodeInfo in class NodeWrapper

Parameters:

other - the node to be compared with this node

Returns:

true if this Node object and the supplied Node object represent the same node in the tree.

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

Since:

9.1 (implemented for this subclass since 9.2)

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:

if the entity exists, return an array of two Strings, the first holding the system ID of the entity (as an absolute URI if possible), 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.

Since:

8.4 (implemented for this subclass since 9.2)

getTypeAnnotation

public int getTypeAnnotation()

Get the type annotation. Always XS_UNTYPED.

Specified by:

getTypeAnnotation in interface NodeInfo

Overrides:

getTypeAnnotation in class NodeWrapper

Returns:

the type annotation of the node, under the mask NamePool.FP_MASK, and optionally the bit setting IS_DTD_TYPE in the case of a DTD-derived ID or IDREF/S type (which is treated as untypedAtomic for the purposes of obtaining the typed value).

For elements and attributes, this is the type annotation as defined in XDM. For document nodes, it should be one of XS_UNTYPED if the document has not been validated, or XS_ANY_TYPE if validation has taken place (that is, if any node in the document has an annotation other than Untyped or UntypedAtomic).

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.
