registerInterceptor

public boolean registerInterceptor(Object theInterceptor)

Description copied from interface: IBaseInterceptorService

Register an interceptor. This method has no effect if the given interceptor is already registered.

Specified by:

registerInterceptor in interface IBaseInterceptorService<POINTCUT extends Enum<POINTCUT> & IPointcut>

Parameters:
