compileToIterator

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

Description copied from class: ExpressionCompiler

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 - if the expression cannot be compiled to bytecode

buildArgumentArray

public static int buildArgumentArray(CompilerService compiler,
                                     Generator ga,
                                     GeneratedMethodInfo methodInfo,
                                     java.util.List<Expression> subExpressions)
                              throws CannotCompileException

Throws:

CannotCompileException
