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)
“We fancy men are individuals; so are pumpkins; but every pumpkin in the field, goes through every point of pumpkin history.”
—Ralph Waldo Emerson (1803–1882)
