|
* Pointcuts that appear inside of declare forms have certain restrictions.
|
|
* Like other pointcuts, these pick out join points, but they do so in a
|
|
* way that is statically determinable.
|
|
*
|
|
* Consequently, such pointcuts may not include, directly or indirectly
|
|
* (through user-defined pointcut declarations) pointcuts that discriminate
|
|
* based on dynamic (runtime) context. Therefore, such pointcuts may not be
|
|
* defined in terms of
|
|
*
|
|
* cflow
|
|
* cflowbelow
|
|
* this
|
|
* target
|
|
* args
|
|
* if
|
|
*
|
|
* all of which can discriminate on runtime information.
