Method Detail

typeCheck

public Type typeCheck(SymbolTable stable)
               throws TypeCheckError
Description copied from class: FunctionCall
Type check a function call. Since different type conversions apply, type checking is different for standard and external (Java) functions.

Overrides:
typeCheck in class FunctionCall
Parameters:
stable - The compiler/parser's symbol table
Throws:
TypeCheckError

translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)
Description copied from class: FunctionCall
Translate a function call. The compiled code will leave the function's return value on the JVM's stack.

Overrides:
translate in class FunctionCall
Parameters:
classGen - BCEL Java class generator
methodGen - BCEL Java method generator
