All Implemented Interfaces:

Runnable

Enclosing class:

AbstractBrowseEntriesPanel

protected class AbstractBrowseEntriesPanel.NumberOfEntriesUpdater
extends Thread

This is a class that simply checks the number of entries that the browser contains and updates a counter with the new number of entries. It is basically a thread that sleeps and checks whether some calculation must be made: when we know that something is updated in the browser the method recalculate() is called. We could use a more sophisticated code (like use a wait() call that would get notified when recalculate() is called) but this is not required and it might have an impact on the reactivity of the UI if recalculate gets called too often. We can afford to wait 400 miliseconds before updating the number of entries and with this approach there is hardly no impact on the reactivity of the UI.
