方法详细资料

on

public static Reflect on(String name)
                  throws ReflectException

参数:

name - 类名

返回:

Reflect

抛出:

ReflectException - Reflect异常

on

public static Reflect on(Class<?> clazz)

参数:

clazz - 类

返回:

Reflect

on

public static Reflect on(Object object)

参数:

object - 对象

返回:

Reflect

accessible

public static <T extends AccessibleObject> T accessible(T accessible)

类型参数:

T - AccessibleObject

参数:

accessible - The object to render accessible

返回:

The argument object rendered accessible

get

public <T> T get()

Get the wrapped object

类型参数:

T - A convenience generic parameter for automatic unsafe casting

返回:

Object

set

public Reflect set(String name,
                   Object value)
            throws ReflectException

Set a field value.

This is roughly equivalent to Field.set(Object, Object). If the wrapped object is a Class, then this will set a value to a static member field. If the wrapped object is any other Object, then this will set a value to an instance member field.

参数:

name - The field name

value - The new field value

返回:

The same wrapped object, to be used for further reflection.

抛出:

ReflectException - If any reflection exception occurred.

get

public <T> T get(String name)
          throws ReflectException

Get a field value.

This is roughly equivalent to Field.get(Object). If the wrapped object is a Class, then this will get a value from a static member field. If the wrapped object is any other Object, then this will get a value from an instance member field.

If you want to "navigate" to a wrapped version of the field, use field(String) instead.

类型参数:

T - The field value Type

参数:

name - The field name

返回:

The field value

抛出:

ReflectException - If any reflection exception occurred.

field(String)

getDeclaredField

public Field getDeclaredField(Class<?> clazz,
                              String name)
                       throws NoSuchFieldException

参数:

clazz - 类

name - 字段名

返回:

字段

抛出:

NoSuchFieldException - NoSuchFieldException

field

public Reflect field(String name)
              throws ReflectException

Get a wrapped field.

This is roughly equivalent to Field.get(Object). If the wrapped object is a Class, then this will wrap a static member field. If the wrapped object is any other Object, then this wrap an instance member field.

参数:

name - The field name

返回:

The wrapped field

抛出:

ReflectException - If any reflection exception occurred.

fields

public Map<String,Reflect> fields()

返回:

A map containing field names and wrapped values.

call

public Reflect call(String name)
             throws ReflectException

Call a method by its name.

参数:

name - The method name

返回:

The wrapped method result or the same wrapped object if the method returns void, to be used for further reflection.

抛出:

ReflectException - If any reflection exception occurred.

另请参阅:

call(String, Object...)

call

public Reflect call(String name,
                    Object... args)
             throws ReflectException

Call a method by its name.

参数:

name - The method name

args - The method arguments

返回:

The wrapped method result or the same wrapped object if the method returns void, to be used for further reflection.

抛出:

ReflectException - If any reflection exception occurred.

create

public Reflect create()
               throws ReflectException

Call a constructor.

返回:

The wrapped new object, to be used for further reflection.

抛出:

ReflectException - If any reflection exception occurred.

另请参阅:

create(Object...)

create

public Reflect create(Object... args)
               throws ReflectException

Call a constructor.

参数:

args - The constructor arguments

返回:

The wrapped new object, to be used for further reflection.

抛出:

ReflectException - If any reflection exception occurred.

as

public <P> P as(Class<P> proxyType)

Create a proxy for the wrapped object allowing to typesafely invoke methods on it using a custom interface

参数:

proxyType - The interface type that is implemented by the proxy

返回:

A proxy for the wrapped object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

equals

public boolean equals(Object obj)

覆盖:

equals 在类中 Object

toString

public String toString()

覆盖:

toString 在类中 Object

type

public Class<?> type()

Get the type of the wrapped object.

另请参阅:

Object.getClass()

wrapper

public static Class<?> wrapper(Class<?> type)

Get a wrapper type for a primitive type, or the argument type itself, if it is not a primitive type.

参数:

type - 类

返回:

类
