Join Point

In computer science, a join point is a point in the control flow of a program. In aspect-oriented programming a set of join points is called a pointcut. A join point is a specification of when, in the corresponding main program, the aspect code should be executed.

The join point is a point of execution in the base code where the advice specified in a corresponding pointcut is applied.

Conceptually, a join point exists where a precondition for a command in Hoare logic makes an assertion parametric upon the joint and several advice supplied by the different concerns at that point in a generalized abstract process, the unified thing composed from its concrete aspects being the pointcut.

Famous quotes containing the words join and/or point:

    I used to join the murmurings about “Where are the qualified women?” As we murmured, we would all gaze about the room, up toward the chandelier, into the corner behind the potted palm, under the napkin, hoping perhaps that qualified women would pop out like leprechauns.
    Jane O’Reilly, U.S. feminist and humorist. The Girl I Left Behind, ch. 5 (1980)

    Parents are led to believe that they must be consistent, that is, always respond to the same issue the same way. Consistency is good up to a point but your child also needs to understand context and subtlety . . . much of adult life is governed by context: what is appropriate in one setting is not appropriate in another; the way something is said may be more important than what is said. . . .
    Stanley I. Greenspan (20th century)
