Method Detail

compileToPush

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

Generate bytecode to evaluate the OuterForExpression in push mode Precondition: none. Postcondition: the stack is empty

Overrides:

compileToPush in class ToIteratorCompiler

Parameters:

compiler - the compiler service

expression - the expression to be compiled

Throws:

CannotCompileException

compileToIterator

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

Generate bytecode to evaluate the OuterForExpression as an iterator Precondition: none. Postcondition: the stack contains an iterator 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
