Method Detail

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

compileToPush

public void compileToPush(CompilerService compiler,
                          Expression expression)
                   throws CannotCompileException
Description copied from class: ExpressionCompiler
Generate bytecode to evaluate the expression in push mode Precondition: none. Postcondition: at execution time, the stack is unchanged, and the value of the expression has been written to the current receiver

Overrides:
compileToPush in class ToIteratorCompiler
Parameters:
compiler - the compiler service
expression - the expression to be compiled
Throws:
CannotCompileException
