Class ReflectiveMethodInvocation

java.lang.Object
  org.springframework.aop.framework.ReflectiveMethodInvocation

All Implemented Interfaces:

org.aopalliance.intercept.Invocation, org.aopalliance.intercept.Joinpoint, org.aopalliance.intercept.MethodInvocation

public class ReflectiveMethodInvocation

extends java.lang.Object

implements org.aopalliance.intercept.MethodInvocation

Spring implementation of AOP Alliance MethodInvocation interface. Invokes target using reflection. Subclasses can override the invokeJoinpoint() method to change this behaviour, so this is a useful base class for MethodInvocation implementations.

Constructor Detail

ReflectiveMethodInvocation

public ReflectiveMethodInvocation(java.lang.Object proxy,
                                  java.lang.Object target,
                                  java.lang.reflect.Method m,
                                  java.lang.Object[] arguments,
                                  java.lang.Class targetClass,
                                  java.util.List interceptorsAndDynamicMethodMatchers)

Construct a new MethodInvocation with given arguments

Parameters:

interceptorsAndDynamicMethodMatchers - interceptors that should be applied, along with any InterceptorAndDynamicMethodMatchers that need evaluation at runtime. MethodMatchers included in this struct must already have been found to have matched as far as was possibly statically. Passing an array might be about 10% faster, but would complicate the code. And it would work only for static pointcuts.

Method Detail

getMethod

public final java.lang.reflect.Method getMethod()

Return the method invoked on the proxied interface. May or may not correspond with a method invoked on an underlying implementation of that interface.

Specified by:

getMethod in interface org.aopalliance.intercept.MethodInvocation

Returns:

Method

getStaticPart

public final java.lang.reflect.AccessibleObject getStaticPart()

Specified by:

getStaticPart in interface org.aopalliance.intercept.Joinpoint

getProxy

public final java.lang.Object getProxy()

Return the proxy that this interception was made through

Returns:

Object

getArguments

public final java.lang.Object[] getArguments()

Private optimization method

Specified by:

getArguments in interface org.aopalliance.intercept.Invocation

Returns:

Object[]

proceed

public java.lang.Object proceed()
                         throws java.lang.Throwable

Specified by:

proceed in interface org.aopalliance.intercept.Joinpoint

Throws:

java.lang.Throwable

See Also:

Joinpoint.proceed()

invokeJoinpoint

protected java.lang.Object invokeJoinpoint()
                                    throws java.lang.Throwable

Invoke the joinpoint using reflection. Subclasses can override this to use custom invocation.

Returns:

the return value of the joinpoint

Throws:

java.lang.Throwable - if invoking the joinpoint resulted in an exception

getThis

public final java.lang.Object getThis()

Specified by:

getThis in interface org.aopalliance.intercept.Joinpoint

See Also:

Joinpoint.getThis()

toString

public java.lang.String toString()
