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:
“If your little savage were left to himself and be allowed to retain all his ignorance, he would in time join the infant’s reasoning to the grown man’s passion, he would strangle his father and sleep with his mother.”
—Denis Diderot (1713–1784)
“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)
