Method Details

getInstructionNameCode
public int getInstructionNameCode()Get the name of this instruction for diagnostic and tracing purposes- Overrides:
getInstructionNameCode
in classApplyImports
- Returns:
- a code identifying the instruction: typically but not always the fingerprint of a name in the XSLT namespace
-
copy
Copy an expression. This makes a deep copy.- Overrides:
copy
in classApplyImports
- Returns:
- the copy of the original expression
-
processLeavingTail
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 interfaceTailCallReturner
- Overrides:
processLeavingTail
in classApplyImports
- 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:
XPathException
- if a dynamic error occurs during the evaluation of the instruction
-
explain
Diagnostic print of expression structure. The abstract expression tree is written to the supplied output destination.- Overrides:
explain
in classApplyImports
- Parameters:
out
- the expression presenter used to display the structure
