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:
“Triumphant Tories, and desponding Whigs,
Forget their feuds, and join to save their wigs.”
—Jonathan Swift (1667–1745)
“Sleaze is a point by point refutation of elegance.”
