Class EventQueueHandler

java.lang.Object

input.EventQueueHandler

public class EventQueueHandler
extends java.lang.Object

Handler for managing event queues. Supports two different type of event queues: external event queues and event generator classes. For external event queues, the events are defined in external data file(s) (see e.g. input.StandarEventsReader). Event generator classes define events dynamically. Both type of event queues must implement the input.EventQueue interface.

The total number of event queues to load is defined with variable NROF_SETTING, e.g.
Events.nrof = 3
Separate event queues are configured with syntax EventsN.variable = value e.g.:
Events1.filePath = ee/messages.txt
or
Events2.class = RandomMessageGenerator

External event files are used when the variable PATH_SETTING is used to define the path to the event file and event generator class is loaded when the name of the class is defined with CLASS_SETTING.
