方法详细资料

getMethod

public Method getMethod()

从接口复制的说明: MethodInvocation

Gets the method being called.

This method is a friendly implementation of the Joinpoint.getStaticPart() method (same result).

指定者:

getMethod 在接口中 MethodInvocation

返回:

the method being called.

getArguments

public Object[] getArguments()

从接口复制的说明: Invocation

Get the arguments as an array object. It is possible to change element values within this array to change the arguments.

指定者:

getArguments 在接口中 Invocation

返回:

the argument of the invocation

setArguments

public void setArguments(Object[] arguments)

从接口复制的说明: ProxyMethodInvocation

Set the arguments to be used on subsequent invocations in the any advice in this chain.

指定者:

setArguments 在接口中 ProxyMethodInvocation

指定者:

setArguments 在类中 AbstractMethodInvocation

参数:

arguments - the argument array

getProxy

public Object getProxy()

从类复制的说明: AbstractMethodInvocation

Return the proxy that this method invocation was made through.

指定者:

getProxy 在接口中 ProxyMethodInvocation

指定者:

getProxy 在类中 AbstractMethodInvocation

返回:

the original proxy object

invokeJoinPoint

protected Object invokeJoinPoint()
                          throws Throwable

从类复制的说明: AbstractMethodInvocation

Invoke jon-point

指定者:

invokeJoinPoint 在类中 AbstractMethodInvocation

返回:

the result of the call to Joinpoint.proceed(), might be intercepted by the interceptor.

抛出:

Throwable

hasInterceptor

protected boolean hasInterceptor()

从类复制的说明: AbstractMethodInvocation

Determine whether there is an interceptor

指定者:

hasInterceptor 在类中 AbstractMethodInvocation

executeInterceptor

protected Object executeInterceptor()
                             throws Throwable

从类复制的说明: AbstractMethodInvocation

Invoke current MethodInterceptor

AbstractMethodInvocation.hasInterceptor() must returnstrue

指定者:

executeInterceptor 在类中 AbstractMethodInvocation

抛出:

Throwable - if the interceptors or the target-object throws an exception.

另请参阅:

• AbstractMethodInvocation.hasInterceptor()

getThis

public Object getThis()

从接口复制的说明: Joinpoint

Returns the object that holds the current joinpoint's static part.

For instance, the target object for an invocation.

指定者:

getThis 在接口中 Joinpoint

返回:

the object (can be null if the accessible object is static).

getTargetClass

public Class<?> getTargetClass()

从接口复制的说明: TargetClassAware

Return the target class behind the implementing object (typically a proxy configuration or an actual proxy).

指定者:

getTargetClass 在接口中 TargetClassAware

返回:

the target Class, or null if not known

getStaticPart

public AccessibleObject getStaticPart()

从接口复制的说明: Joinpoint

Returns the static part of this joinpoint.

The static part is an accessible object on which a chain of interceptors are installed.

指定者:

getStaticPart 在接口中 Joinpoint

equals

public boolean equals(Object o)

覆盖:

equals 在类中 infra.core.AttributeAccessorSupport

hashCode

public int hashCode()

覆盖:

hashCode 在类中 infra.core.AttributeAccessorSupport

toString

public String toString()

覆盖:

toString 在类中 Object
