Method Detail

getDescriptorFilter

public Filter getDescriptorFilter()

Description copied from interface: InterceptionService

If the returned filter returns true then the methods of the service will be passed to InterceptionService.getMethodInterceptors(Method) to determine if a method should be intercepted and the constructor of the service will be passed to InterceptionService.getConstructorInterceptors(Constructor) to determine if the constructor should be intercepted

Specified by:

getDescriptorFilter in interface InterceptionService

Returns:

The filter that will be applied to a descriptor to determine if it is to be intercepted. Should not return null

getMethodInterceptors

public List<org.aopalliance.intercept.MethodInterceptor> getMethodInterceptors(Method method)

Description copied from interface: InterceptionService

Each non-final method of a service that passes the InterceptionService.getDescriptorFilter() method will be passed to this method to determine if it will intercepted

Specified by:

getMethodInterceptors in interface InterceptionService

Parameters:

method - A non-final method that may be intercepted

Returns:

if null (or an empty list) then this method should NOT be intercepted. Otherwise the list of interceptors to apply to this method

getConstructorInterceptors

public List<org.aopalliance.intercept.ConstructorInterceptor> getConstructorInterceptors(Constructor<?> constructor)

Description copied from interface: InterceptionService

The single chosen constructor of a service that passes the InterceptionService.getDescriptorFilter() method will be passed to this method to determine if it will intercepted

Specified by:

getConstructorInterceptors in interface InterceptionService

Parameters:

constructor - A constructor that may be intercepted

Returns:

if null (or an empty list) then this constructor should NOT be intercepted. Otherwise the list of interceptors to apply to this method
