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

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.

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

makeNumberer

public static Numberer makeNumberer(java.lang.String language)
Load a Numberer class for a given language and check it is OK.

Parameters:
language - the language for which a Numberer is required
Returns:
a suitable numberer. If no specific numberer is available for the language, the default (English) numberer is used.
