Class TriggeredEventWorker

java.lang.Object

eu.vicci.process.model.sofiainstance.util.TriggeredEventWorker

public class TriggeredEventWorker
extends Object

The worker blocks till the event which is specified in the EPL statement is received. If there are any enddataports, values which are received by the event are get and datatypeinstances are created. To receive a value, the endport must have a datatype, which name equals the var in the select (e.g. datatype name = 'value', epl stmt = select value from...). The datatype should be the type of the value you want to receive (e.g. value is double -> DoubleType for the port)
