方法详细资料

getRootMethod

public static Method getRootMethod(Method m)

Get root of the method.

getRootMethods

public static Method[] getRootMethods(Class<?> clz)

Get root methods of the class.

getRootField

public static Field getRootField(Field f)

Get root of the field.

getRootFields

public static Field[] getRootFields(Class<?> clz)

Get root fields of the class.

getFieldValue

public static <T,O> O getFieldValue(Class<T> clz,
                                    T t,
                                    String fieldName)
                             throws NoSuchFieldException

抛出:

NoSuchFieldException

getAllFields

public static Field[] getAllFields(Class<?> clz,
                                   boolean includeStatic)

Get both private and inherit fields

参数:

clz -

返回:

getCallerClassName

public static String getCallerClassName()

Get the name of the class who calls the caller.
For example. The following code will print "A".

 class A {
   static void fun() {
     B.fun();
   }
 }

 class B {
   static void fun() {
     System.out.println(ReflectUtil.getCallerClassName());
   }
 }
 

返回:

getCaller

public static StackTraceElement getCaller()

getCaller

public static StackTraceElement getCaller(int deep,
                                          boolean ignoreSameClass)

Get caller stack info.

参数:

deep - Deep to search the caller class.If deep is 0, it returns the class who calls this method.

ignoreSameClass - If it is true, calling in same class will be ignored.

返回:
