Method Detail

evaluate

public Value evaluate()

Return the value of the right operand, which is a variable. Since parser does not classify * as a dereference operator unless it is followed by a pointer variable, not checking that the RHS is a pointer.

Overrides:

evaluate in class Operator

public static void main(java.lang.String[] args)
