ca.uqac.lif.synthia.Reactive< U, T > Interface Template Reference

Detailed Description

Interface implemented by pickers whose picking of objects can be altered by external information.

To this end, a reactive picker provides a method called tell, which is used to pass an object that the picker may use to modify its internal state or the way the next value will be produced.

A simple example of a reactive picker is RandomInteger; in this case, method tell is used to modify the upper bound of its range of possible values. RandomBoolean uses tell to modify the probability of producing value true, and PoissonInteger uses it to modify its parameter λ.

Reactive pickers are especially useful in the context of testing of an interactive component, such as a user interface.
