Class GeneratedInstanceAdvisorMixin

java.lang.Object

org.jboss.aop.GeneratedInstanceAdvisorMixin

All Implemented Interfaces:

Serializable, InstanceAdvisor

public class GeneratedInstanceAdvisorMixin
extends Object
implements InstanceAdvisor, Serializable

Adapts the old instance advisor api to the new generated advisor stuff. Old API calls on generated instance advisors will delegate to this class

For internal use only.

Specified by:

getPerInstanceAspect in interface InstanceAdvisor

Parameters:

def - definition of the queried aspect

Returns:

the per instance aspect defined by def

getPerInstanceJoinpointAspect

public Object getPerInstanceJoinpointAspect(Joinpoint joinpoint,
                                   AspectDefinition def)

Description copied from interface: InstanceAdvisor

Returns the per instance joinpoint aspect object defined by def to be applied at joipoint.
Notice that the aspect objects are created by JBoss AOP, either by using an aspect factory or by using the constructor of an aspect class.

For internal use only.

Specified by:

getPerInstanceJoinpointAspect in interface InstanceAdvisor

Parameters:

joinpoint - the joinpoint to which the aspect object will be applied.

def - definition of the queried aspect

Returns:

the per instance joinpoint aspect defined by def to be applied at joinpoint

getMetaData

public SimpleMetaData getMetaData()

Description copied from interface: InstanceAdvisor

Returns the metadata bound to the advised instance.

Specified by:

getMetaData in interface InstanceAdvisor

Returns:

the metadata bound to the advised instance.

getInterceptors

public Interceptor[] getInterceptors()

Description copied from interface: InstanceAdvisor

Returns the interceptor chain of the advised instance.

For internal use only.

Specified by:

getInterceptors in interface InstanceAdvisor

Returns:

the interceptor chain of the advised instance.

getInterceptors

public Interceptor[] getInterceptors(Interceptor[] advisorChain)

Called by the advisor

Specified by:

getInterceptors in interface InstanceAdvisor

Parameters:

advisorChain - the chain to be joined with the advised instance's chain.

Returns:

a new interception chain as a result of the merge of baseChain with the instance's chain. May return baseChain if the last one is empty.

getWrappers

public GeneratedAdvisorInterceptor[] getWrappers()

getWrappers

public Interceptor[] getWrappers(Interceptor[] advisorChain)

Called by the advisor

Parameters:

An - array of GeneratedAdvisorInterceptor from the advisor's intereceptor chain for the joinpoint
