Detailed Description

Manager that works with IEventCounterFactory . Create EventCounter for each registered IEventCounterFactory and send corresponding events when calling OnEvent(iText.Kernel.Counter.Event.IEvent, iText.Kernel.Counter.Event.IMetaInfo, System.Type) method.

You can implement your own IEventCounterFactory and register them with Register(IEventCounterFactory) Or implement EventCounter and register it with SimpleEventCounterFactory like this: EventCounterManager.getInstance().register(new SimpleEventCounterFactory(new SystemOutEventCounter()); SystemOutEventCounter is just an example of a EventCounter implementation.

This functionality can be used to create metrics in a SaaS context.
