      • isStaticCall

        public static boolean isStaticCall​(byte opcode)
        Check if an instruction opcode refers to a static call (i.e. no calling instance needed).
        参数:
        opcode - The instruction opcode to check
        返回:
        False if this call requires a calling instance, true otherwise.
