Detailed Description

An abstract observable type, maintaining a list of observers, who can be notified in case of Events.

Some known observable types are Tracker and Endgame.

Member Function Documentation

AddObserver()

void bertini::Observable::AddObserver ( AnyObserver & new_observer ) const

inline

Add an observer, to observe this observable.

NotifyObservers()

void bertini::Observable::NotifyObservers ( AnyEvent const & e ) const

inlineprotected

Sends an Event (more particularly, AnyEvent) to all watching observers of this object.

This function could potentially be improved by filtering on the observer's desired event types, if known at compile time. This could potentially be a performance bottleneck (hopefully not!) since filtering can use dynamic_casting. One hopes this cost is overwhelmed by things like linear algebra and system evaluation.

Parameters

e	The event to emit. Its type should be derived from AnyEvent.

Here is the caller graph for this function:

RemoveObserver()

void bertini::Observable::RemoveObserver ( AnyObserver & observer ) const

inline

Remove an observer from this observable.
