de.hshannover.dqgui.framework.WindowInstances

public final class WindowInstances
extends java.lang.Object

Amount of window instances that can exist at the time of a view managed by the ApplicationContext.
Managed by identifier means that there can be n instances but they correspond to an identifier so calling them again will force the window in the foreground if a window with the called identifier is already loaded.
