ApplyTemplates

public ApplyTemplates(Expression select,
                      WithParam[] actualParams,
                      WithParam[] tunnelParams,

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

getInstructionDetails

public InstructionDetails getInstructionDetails(Controller controller)
Contruct details of an InstructionInfo for use by the TraceListener.

Overrides:
getInstructionDetails in class Instruction
Parameters:
controller - the Controller for the transformation. This is supplied because (to save space) the Executable is not reachable from an individual Instruction
Returns:
an object containing information about the instruction, designed for use by a TraceListener

process

public void process(XPathContext context)
             throws TransformerException
Description copied from class: Instruction
Process the instruction, without returning any tail calls

Overrides:
process in class Instruction
Parameters:
context - The dynamic context, giving access to the current node, the current variables, etc.
Throws:
TransformerException

processLeavingTail

public TailCall processLeavingTail(XPathContext context)
                            throws 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:
TransformerException
