public interface Subject

Implementation of the Observer pattern.
This implementation is tailored for the async operation of WebDriver. This interface assumes you are familiar with the observer pattern.
To learn more about observers visit the wikipedia site The subject is closely coupled with the co.verisoft.selenium.framework.async.Observer class In this framework, the subject is implemented by co.verisoft.selenium.framework.async.AsyncListenerImp
The interface was designed to be triggered without any data, rather serve as a trigger for async scripts to perform their async operation

Since:

2.0.3

Method Summary

Modifier and Type	Method	Description
void	notifyObservers()	Notify all observers when time is due to execute async Typically, when the implementation uses an ArrayList to keep track of all the observes, this method will loop through the list and activate the update method for each observer
void	register(Observer o)	Registers a new observer to be notified.
void	unregister(Observer o)	Unregister an existing observer, and stop notifying the observer upon invocation of notifyObservers method

Method Details

register

void register(Observer o)

Registers a new observer to be notified. Typically it adds an object which implements the Observer interface to an ArrayList. Once the observer is on the list, each invocation of notify will trigger an update for all observers on the list

Parameters:

o - Observer object to be added

unregister

void unregister(Observer o)

Unregister an existing observer, and stop notifying the observer upon invocation of notifyObservers method

Parameters:

o - Observer object to be removed

notifyObservers

void notifyObservers()

Notify all observers when time is due to execute async Typically, when the implementation uses an ArrayList to keep track of all the observes, this method will loop through the list and activate the update method for each observer
