compileToIterator
public void compileToIterator(CompilerService compiler, Expression expression) throws CannotCompileException
Description copied from class:ExpressionCompilerGenerate bytecode to evaluate the expression as aSequenceIteratorPrecondition: none. Postcondition: at execution time, the stack contains a SequenceIterator representing the result of the expression- Specified by:
compileToIteratorin classExpressionCompiler- Parameters:
compiler- the compiler serviceexpression- the expression to be compiled- Throws:
CannotCompileException- if the expression cannot be compiled to bytecode
-
compileToPush
public void compileToPush(CompilerService compiler, Expression expression) throws CannotCompileException
Description copied from class:ExpressionCompilerGenerate 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:
compileToPushin classToIteratorCompiler- Parameters:
compiler- the compiler serviceexpression- the expression to be compiled- Throws:
CannotCompileException- if the expression cannot be compiled to bytecode
