Class IIOProviderContextListener

java.lang.Object

fr.sertelon.media.IIOProviderContextListener

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener

public final class IIOProviderContextListener
extends Object
implements javax.servlet.ServletContextListener

Takes care of registering and de-registering local ImageIO plugins (service providers) for the servlet context.

Registers all available plugins on contextInitialized event, using ImageIO.scanForPlugins(), to make sure they are available to the current servlet context. De-registers all plugins which have the current thread's context class loader as its class loader on contextDestroyed event, to avoid class/resource leak.
