All Known Implementing Classes:

ActivityRecordObservableBase, SynchronizationRecordObservable, CallRecordObservable

public interface ObservableRecord

ObservableRecord -- interface for activity records which may be observed by ChangeObservers

Method Summary

void	addChangeObserver(ChangeObserver observer)
boolean	isReadOnly() may be used to avoid constructing change observers for records that will never change.
void	removeChangeObserver(ChangeObserver observer)

Method Detail

addChangeObserver

public void addChangeObserver(ChangeObserver observer)

removeChangeObserver

public void removeChangeObserver(ChangeObserver observer)

isReadOnly

public boolean isReadOnly()

may be used to avoid constructing change observers for records that will never change. If true, should never become false. (Often different from ActivityRecord.isFinished(), which only means the thread that created the activity record is finished with it, not that other threads are.)
