Constructor Detail

UpdateControlBehavior

public UpdateControlBehavior()

Create a new behavior that manages the update of a single entity

Method Detail

isUpdating

public boolean isUpdating()

Check to see if the manager is making updates right now.

Specified by:

isUpdating in interface UpdateManager

Returns:

true if the update process is currently happening

setUpdating

public void setUpdating(boolean updating)

Instruct the system to start or stop the update process. This is used to control the whole threaded update system rather than interact with a single update request.

Specified by:

setUpdating in interface UpdateManager

Parameters:

updating - true to set the update to happen, false to stop

updateRequested

public void updateRequested(UpdatableEntity ue)

Request that the manager update this item. This will be scheduled to happen as soon as possible, but won't necessarily happen immediately.

Specified by:

updateRequested in interface UpdateManager

Parameters:

ue - The entity to be updated

initialize

public void initialize()

Initialize the behavior to start working now. Sets up the initial wakeup condition.

processStimulus

public void processStimulus(java.util.Enumeration conditions)

Process the behavior that has been woken up by the given set of conditions.

Parameters:

conditions - The list of conditions satisfied
