Class callback (callback/callbacks/bumper.h)

Overview

Class callback is a polymorphic wrapper for lambda functions that gives them an interface in order to interact correctly with the dispatcher. This callback is completely specialized for events :: bumper and can be built only with lambdas that take as argument a report <events :: bumper> object.

Interface

Constructor

• callback(const lambda & function)

  builds the callback with the given function.

Methods

• void trigger(const events :: bumper & event)

  given an event of the correct kind, sets off the lambda function by giving it as argument a report about the given event.
