setControllingInstruction
Set the containing xsl:for-each-group instruction, if there is one- Parameters:
instruction
- the (innermost) containing xsl:for-each-group instruction
-
getControllingInstruction
Get the innermost containing xsl:merge instruction, if there is one- Returns:
- the innermost containing xsl:merge instruction
-
makeFunctionCall
Make an expression that either calls this function, or that is equivalent to a call on this function- Overrides:
makeFunctionCall
in classSystemFunction
- Parameters:
arguments
- the supplied arguments to the function call- Returns:
- either a function call on this function, or an expression that delivers the same result
-
iterate
Evaluate the expression- Throws:
XPathException
-
call
Evaluate the expression- Specified by:
call
in interfaceCallable
- Parameters:
context
- the dynamic evaluation contextarguments
- the values of the arguments, supplied as SequenceIterators- Returns:
- the result of the evaluation, in the form of a SequenceIterator
- Throws:
XPathException
- if a dynamic error occurs during the evaluation of the expression
