Constructor Detail

Copy

public Copy(AttributeSet[] useAttributeSets,
            boolean copyNamespaces,
            SchemaType schemaType,
            int validation)

getInstructionName

public java.lang.String getInstructionName()

Get the name of this instruction for diagnostic and tracing purposes

Specified by:

getInstructionName in class Instruction

getNameCode

protected int getNameCode(XPathContext context)
                   throws javax.xml.transform.TransformerException

Callback from ElementCreator when constructing an element

Specified by:

getNameCode in class ElementCreator

Parameters:

context -

Returns:

the namecode of the element to be constructed

Throws:

javax.xml.transform.TransformerException

outputNamespaceNodes

protected void outputNamespaceNodes(XPathContext context,
                                    Receiver receiver)
                             throws javax.xml.transform.TransformerException

Callback to output namespace nodes for the new element.

Specified by:

outputNamespaceNodes in class ElementCreator

Parameters:

context - The execution context

receiver - the Receiver where the namespace nodes are to be written

Throws:

javax.xml.transform.TransformerException

processLeavingTail

public TailCall processLeavingTail(XPathContext context)
                            throws javax.xml.transform.TransformerException

Description copied from class: ElementCreator

Evaluate the instruction to produce a new element node

Specified by:

processLeavingTail in interface Instr

Overrides:

processLeavingTail in class ElementCreator

Parameters:

context -

Returns:

null (this instruction never returns a tail call)

Throws:

javax.xml.transform.TransformerException

getXPathExpressions

protected void getXPathExpressions(java.util.List list)

Description copied from class: ExprInstruction

Get all the XPath expressions associated with this instruction (in XSLT terms, the expression present on attributes of the instruction, as distinct from the child instructions in a sequence construction)

Specified by:

getXPathExpressions in class ExprInstruction

Parameters:

list - A list to be populated with the list of XPath expressions

display

public void display(int level,
                    NamePool pool)

Diagnostic print of expression structure. The expression is written to the System.err output stream

Parameters:

level - indentation level for this expression
