Method Detail

addEventListener

public void addEventListener(HomeHealthEventListenerIF listener)

Adds a scoring listener to this grouper

Specified by:

addEventListener in interface HomeHealthEventNotifierIF

Parameters:

listener -

getEventListeners

public java.util.Iterator<HomeHealthEventListenerIF> getEventListeners()

gets an iterator for the event listeners

Specified by:

getEventListeners in interface HomeHealthEventNotifierIF

Returns:

An iterator of the scoring listeners. Will not be null, but may not have any listeners to iterator over

getEventListenersList

public java.util.List<HomeHealthEventListenerIF> getEventListenersList()

gets an iterator for the event listeners

Specified by:

getEventListenersList in interface HomeHealthEventNotifierIF

Returns:

An iterator of the scoring listeners. Will not be null, but may not have any listeners to iterator over

notifyEventListeners

public void notifyEventListeners(HomeHealthEventIF event)

If there are listener, the send them the event and let them do what they want.

Specified by:

notifyEventListeners in interface HomeHealthEventNotifierIF

Parameters:

event -

removeEventListener

Specified by:

removeEventListener in interface HomeHealthEventNotifierIF

Parameters:

listener -

public void removeEventListeners()

Removes all the listeners from this Grouper

Specified by:

removeEventListeners in interface HomeHealthEventNotifierIF

getListenerCount

public int getListenerCount()

This a useful when determine when to report events. Since some reporting takes up processing time unrelated to actual scoring, determine if reporting is necessary (i.e. listeners count > 0) helps to cut down on any unnecessary processing/building of the detailed event information. See the fireScoring... methods for examples of this.

Specified by:

getListenerCount in interface HomeHealthEventNotifierIF

Returns:

the number of listeners for this Grouper
