Examples of javassist.bytecode.Bytecode.addInvokeinterface()

javassist.bytecode.Bytecode.addInvokeinterface()
Appends INVOKEINTERFACE. @param clazz the target class. @param name the method name @param returnType the return type. @param paramTypes the parameter types. @param count the count operand of the instruction.

    Bytecode code = new Bytecode(cp, 6, 3);
    // aload_0
    code.addAload(0);
    // invokeinterface // enabled.getInterceptFieldCallback()
    int enabled_class_index = cp.addClassInfo(FIELD_HANDLED_TYPE_NAME);
    code.addInvokeinterface(enabled_class_index,
                            GETFIELDHANDLER_METHOD_NAME, GETFIELDHANDLER_METHOD_DESCRIPTOR,
                            1);
    // ifnonnull (label1)
    code.addOpcode(Opcode.IFNONNULL);
