public class JavaExtensionFunctionCallCompiler
extends ToIteratorCompiler

Compiles a call to an old-style "reflexive" Java extension function. When compiled, the call is no longer reflexive, but is a direct call on the underlying method.

compileToIterator

public void compileToIterator(CompilerService compiler,
                              Expression expression)
                       throws CannotCompileException

Generate bytecode to evaluate the expression as a SequenceIterator Precondition: none. Postcondition: at execution time, the stack contains a SequenceIterator representing the result of the expression

Specified by:

compileToIterator in class ExpressionCompiler

Parameters:

compiler - the compiler service

expression - the expression to be compiled

Throws:

CannotCompileException
