autoCast

protected void autoCast(AClass original,
            AClass target,
            boolean enforce)

Auto cast top element of stack from original type to target type.

support auto cast type :

1. primitive type to wrapper type(box)
2. wrapper type to primitive type(unbox)
3. low type to high type
4. if enforce is true : allow high type to low type

参数:

original -

target -

enforce -

getCompileOrder

public final int getCompileOrder()

getOperatorSymbol

public Operator getOperatorSymbol()
