void	addDepend(Dependent c) adds a Dependent class to be notified on marking change

void	delDepend(Dependent c) removes a Dependent class from the list of classes to be notified on marking change
void	endBatch() ends batch mode. if any notification reqests has been made since beginBatch() then the last one will be passed to dependents. otherwise just batch flag is cleared and no notification is sent.
void	NotifyAll(NotifyMsg msg) notifies all Dependent classes in the notify list of a change.
void	NotifyAll(NotifyMsg msg, Dependent c) notifies all Dependent classes in the notify list of a change, except for the specified class.
void	NotifyAll(NotifyMsg msg, Dependent c, java.util.Vector path) general NotifyAll
void	NotifyAll(NotifyMsg msg, java.util.Vector path)
void	startCascadedNotifyAll(NotifyMsg msg) initiates cascaded notification process. use this method instead of NotifyAll if you want to make sure that also inderect dependents will recieve the notification

NotifyAll

public void NotifyAll(NotifyMsg msg,
                      java.util.Vector path)

startCascadedNotifyAll

public void startCascadedNotifyAll(NotifyMsg msg)

initiates cascaded notification process. use this method instead of NotifyAll if you want to make sure that also inderect dependents will recieve the notification

NotifyAll

public void NotifyAll(NotifyMsg msg,
                      Dependent c,
                      java.util.Vector path)

general NotifyAll

NotifyAll

public void NotifyAll(NotifyMsg msg)

notifies all Dependent classes in the notify list of a change. (Results in calling NotifyAll(org.rosuda.ibase.NotifyMsg, org.rosuda.ibase.Dependent) with NULL parameter

beginBatch

public void beginBatch()

initiates batch mode - in this mode no notifications are made until endBatch() has been called. batch mode begin/end calls may be nested, but only after last endBatch notification is made.
