Class AspectSystemImpl

java.lang.Object
  org.mockejb.interceptor.AspectSystemImpl

All Implemented Interfaces:

AspectSystem

public class AspectSystemImpl

extends java.lang.Object

implements AspectSystem

Provides the implementation of the AspectSystem by adding aspects to the list and providing access to this list. Note that all "add" method first check if the same aspect is already in the list. If it is, the aspect is removed from the list and then added again. This is to prevent having the same aspect in the list multiple times. Aspect's "equals" method is used to compare aspects/interceptors, so it is the aspect providers must have this method implemented.

Method Detail

add

public void add(Aspect aspect)

Description copied from interface: AspectSystem

Adds the given aspect to the end of the global list of aspects.

Specified by:

add in interface AspectSystem

Parameters:

aspect - aspect to add

See Also:

AspectSystem.add(org.mockejb.interceptor.Aspect)

addFirst

public void addFirst(Aspect aspect)

Description copied from interface: AspectSystem

Inserts the given aspect in the beginning of the list of aspects. If you want an interceptor for a given pointcut to be called before other interceptors for the same pointcut, you can use this method.

Specified by:

addFirst in interface AspectSystem

Parameters:

aspect - aspect to add

See Also:

AspectSystem.addFirst(org.mockejb.interceptor.Aspect)

add

public void add(Pointcut pointcut,
                Interceptor interceptor)

Description copied from interface: AspectSystem

Creates the new aspect and adds it to the end of the list of aspects.

Specified by:

add in interface AspectSystem

Parameters:

pointcut - pointcut of the aspect

interceptor - interceptor of the aspect

See Also:

AspectSystem.add(org.mockejb.interceptor.Pointcut, org.mockejb.interceptor.Interceptor)

addFirst

public void addFirst(Pointcut pointcut,
                     Interceptor interceptor)

Description copied from interface: AspectSystem

Creates the new aspect from the given pointcut and the interceptor and inserts it in the beginning of the list of aspects. If you want an interceptor for a given pointcut to be called before other interceptors for the same pointcut, you can use this method.

Specified by:

addFirst in interface AspectSystem

Parameters:

pointcut - pointcut of the aspect

interceptor - interceptor of the aspect

See Also:

AspectSystem.addFirst(org.mockejb.interceptor.Pointcut, org.mockejb.interceptor.Interceptor)

removeIfExists

protected void removeIfExists(Aspect aspect)

getAspectList

public java.util.List getAspectList()

Description copied from interface: AspectSystem

Returns the list of aspects to the client. Clients can manipulate the list.

Specified by:

getAspectList in interface AspectSystem

Returns:

the list of aspects

See Also:

AspectSystem.getAspectList()

clear

public void clear()

Clears the list of aspects for this AspectSystem

Specified by:

clear in interface AspectSystem

findInterceptors

public java.util.List findInterceptors(java.lang.reflect.Method proxyMethod,
                                       java.lang.reflect.Method targetMethod)

Description copied from interface: AspectSystem

Identifiesaspects whose pointcut matches the given source method or target method. Returns the list of the interceptors for the matching pointcuts.

Specified by:

findInterceptors in interface AspectSystem

Parameters:

proxyMethod - method invoked by the client on the proxy (interface method)

targetMethod - target method which will be called as the result of the proxy method

Returns:

list of the interceptors for the matching pointcuts

AspectSystem.findInterceptors(java.lang.reflect.Method, java.lang.reflect.Method)
