Method Detail

setInstructionDetails

public void setInstructionDetails(Controller controller,
                                  NamePool namePool,
                                  InstructionDetails details)
Get the name of this instruction for diagnostic and tracing purposes

Specified by:
setInstructionDetails in class Instruction
Returns:
the string "xsl:namespace"

getResultType

public SequenceType getResultType()
Description copied from class: Instruction
Get the static type of the value returned by the instruction

Overrides:
getResultType in class Instruction
Returns:
the SequenceType that the returned value will conform to.

promoteInst

public void promoteInst(PromotionOffer offer)
Specified by:
promoteInst in class ExprInstruction

typeCheck

public void typeCheck(StaticContext env)
Specified by:
typeCheck in class SimpleNodeConstructor

getXPathExpressions

public void getXPathExpressions(java.util.List list)
Overrides:
getXPathExpressions in class SimpleNodeConstructor

processLeavingTail

public TailCall processLeavingTail(XPathContext context)
                            throws javax.xml.transform.TransformerException
Description copied from class: Instruction
ProcessLeavingTail: called to do the real work of this instruction. This method must be implemented in each subclass. The results of the instruction are written to the current Receiver, which can be obtained via the Controller.

Specified by:
processLeavingTail in class Instruction
Parameters:
context - The dynamic context of the transformation, giving access to the current node, the current variables, etc.
Returns:
null if the instruction has completed execution; or a TailCall indicating a function call or template call that is delegated to the caller, to be made after the stack has been unwound so as to save stack space.
Throws:
javax.xml.transform.TransformerException

display

public void display(int level,
                    NamePool pool)
Display this instruction as an expression, for diagnostics

Specified by:
display in interface Expression
Overrides:
display in class SimpleNodeConstructor
