反射之getDeclaredMethod和getMethod

先看看源码
getMethods：获取当前类和父类的所有public的方法，包括由类或接口声明的对象，以及从超类和接口继承的的方法

	@CallerSensitive
    public Method[] getMethods() throws SecurityException {
        checkMemberAccess(Member.PUBLIC, Reflection.getCallerClass(), true);
        return copyMethods(privateGetPublicMethods());   // 调用下面的
    }

	 private Method[] privateGetPublicMethods() {
        checkInitted();
        Method[] res;
        ReflectionData<T> rd = reflectionData();
        if (rd != null) {
            res = rd.publicMethods;
            if (res != null) return res;
        }

        // No cached value available; compute value recursively.
        // Start by fetching public declared methods
        MethodArray methods = new MethodArray();
        {
            Method[] tmp = privateGetDeclaredMethods(true);  // 调用下面的 参数为true 区别
            methods.addAll(tmp);
        }
        .......
   }
=======>>>>> publicOnly ==> true 所以源码也可以得到只拿公有的 <<<<<<<============

	 private Method[] privateGetDeclaredMethods(boolean publicOnly) {
        checkInitted();
        Method[] res;
        ReflectionData<T> rd = reflectionData();
        if (rd != null) {
            res = publicOnly ? rd.declaredPublicMethods : rd.declaredMethods;
            if (res != null) return res;
        }
        // No cached value available; request value from VM
        res = Reflection.filterMethods(this, getDeclaredMethods0(publicOnly));
        if (rd != null) {
            if (publicOnly) {
                rd.declaredPublicMethods = res;
            } else {
                rd.declaredMethods = res;
            }
        }
        return res;
    }

getDeclaredMethods: 获取当前类的所有声明的方法，包括public、protected和private修饰的方法

	@CallerSensitive
    public Method[] getDeclaredMethods() throws SecurityException {
        checkMemberAccess(Member.DECLARED, Reflection.getCallerClass(), true);
        return copyMethods(privateGetDeclaredMethods(false)); // 调用下面的方法 参数为false
    }
    
	=======>>>>> publicOnly ==> false；<<<<<<<============
	
	private Method[] privateGetDeclaredMethods(boolean publicOnly) {
        checkInitted();
        Method[] res;
        ReflectionData<T> rd = reflectionData();
        if (rd != null) {
            res = publicOnly ? rd.declaredPublicMethods : rd.declaredMethods;
            if (res != null) return res;
        }
        // No cached value available; request value from VM
        res = Reflection.filterMethods(this, getDeclaredMethods0(publicOnly));
        if (rd != null) {
            if (publicOnly) {
                rd.declaredPublicMethods = res;
            } else {
                rd.declaredMethods = res;
            }
        }
        return res;
    }

综上只是自己看源码发现的 如果有不对的地方 请批评指正，谢谢！
