Parameters:

config - the Saxon configuration

Method Detail

makeElementNode

public ElementImpl makeElementNode(NodeInfo parent,
                                   int nameCode,
                                   int typeCode,
                                   AttributeCollectionImpl attlist,
                                   int[] namespaces,
                                   int namespacesUsed,
                                   PipelineConfiguration pipe,
                                   int locationId,
                                   int sequence)

Create an Element node. Note, if there is an error detected while constructing the Element, we add the element anyway, and return success, but flag the element with a validation error. This allows us to report more than one error from a single compilation.

Specified by:

makeElementNode in interface NodeFactory

Parameters:

nameCode - The element name

typeCode -

attlist - the attribute list

parent - The parent element

namespaces - List of new namespace declarations for this element, as a sequence of namespace codes representing pairs of strings: (prefix1, uri1), (prefix2, uri2)...

namespacesUsed - the number of elemnts of the namespaces array actually used

pipe - The pipeline configuration (provides access to the error listener and the location provider)

locationId - Indicates the source document and line number containing the node

sequence - Sequence number to be assigned to represent document order.

makeXSLElement

protected StyleElement makeXSLElement(int f)

Make an XSL element node

Parameters:

f - the fingerprint of the node name

Returns:

the constructed element node

isElementAvailable

public boolean isElementAvailable(String uri,
                                  String localName)

Method to support the element-available() function

Parameters:

uri - the namespace URI

localName - the local Name

Returns:

true if an extension element of this name is recognized
