WithParam
public WithParam()
getInstructionNameCode
public int getInstructionNameCode()
- Description copied from class:
Instruction
- Get the namecode of the instruction for use in diagnostics
- Overrides:
getInstructionNameCode
in class GeneralVariable
processLeavingTail
public TailCall processLeavingTail(XPathContext context)
throws XPathException
- 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.
XPathException
simplify
public static void simplify(WithParam[] params,
StaticContext env)
throws XPathException
XPathException
analyze
public static void analyze(WithParam[] params,
StaticContext env,
ItemType contextItemType)
throws XPathException
XPathException
promoteParams
public static void promoteParams(WithParam[] params,
PromotionOffer offer)
throws XPathException
- Promote the expressions in a set of with-param elements. This is a convenience
method for use by subclasses.
XPathException
getXPathExpressions
public static void getXPathExpressions(WithParam[] params,
java.util.List list)
- Get the XPath expressions used in an array of WithParam parameters (add them to the supplied list)
evaluateVariable
public Value evaluateVariable(XPathContext context)
throws XPathException
- Evaluate the variable (method exists only to satisfy the interface)
