Constructor Detail

StyleNodeFactory

public StyleNodeFactory(Configuration config,
                        Compilation compilation)

Create the node factory for representing an XSLT stylesheet as a tree structure

Parameters:

config - the Saxon configuration

compilation - the compilation episode (compiling one package)

Method Detail

setTopLevelModule

public void setTopLevelModule(boolean topLevelModule)

Say that this is the top-level module of a package

Parameters:

topLevelModule - true if this stylesheet module is the top level of a package; false if it is included or imported

isTopLevelModule

public boolean isTopLevelModule()

Ask whether this is the top-level module of a package

Returns:

true if this stylesheet module is the top level of a package; false if it is included or imported

getCompilation

public Compilation getCompilation()

getConfiguration

public Configuration getConfiguration()

makeElementNode

public ElementImpl makeElementNode(NodeInfo parent,
                                   NodeName elemName,
                                   SchemaType elemType,
                                   boolean isNilled,
                                   AttributeCollectionImpl attlist,
                                   NamespaceBinding[] namespaces,
                                   int namespacesUsed,
                                   PipelineConfiguration pipe,
                                   Location location,
                                   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:

parent - The parent element

elemName - The element name

elemType - The type annotation of the element

isNilled - true if the element is to be marked as nilled

attlist - The attribute collection, excluding any namespace attributes

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)

location - 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,
                                      NodeImpl parent)

Make an XSL element node

Parameters:

f - the fingerprint of the node name

parent - the parent node

Returns:

the constructed element node

makeTextNode

public TextImpl makeTextNode(NodeInfo parent,
                             java.lang.CharSequence content)

Make a text node

Specified by:

makeTextNode in interface NodeFactory

Parameters:

content - the content of the text node

Returns:

the constructed text node

isElementAvailable

public boolean isElementAvailable(java.lang.String uri,
                                  java.lang.String localName,
                                  boolean instructionsOnly)

Method to support the element-available() function

Parameters:

uri - the namespace URI

localName - the local Name

instructionsOnly - true if only instruction elements qualify

Returns:

true if an extension element of this name is recognized

makeAccumulatorManager

public AccumulatorRegistry makeAccumulatorManager()

newPrincipalModule

public PrincipalStylesheetModule newPrincipalModule(XSLPackage node)
                                             throws XPathException

Create a stylesheet package

Parameters:

node - the XSLPackage element

Returns:

a new stylesheet package

Throws:

XPathException
