Class ProcessStreamReceiver

java.lang.Object

org.wso2.siddhi.core.query.input.ProcessStreamReceiver

All Implemented Interfaces:

StreamJunction.Receiver

Direct Known Subclasses:

MultiProcessStreamReceiver, SingleProcessStreamReceiver

public class ProcessStreamReceiver
extends Object
implements StreamJunction.Receiver

Parent implementation for all process stream receivers(Multi/Single/State). Any newly written process stream receivers should extend this. ProcessStreamReceivers are the entry point to Siddhi queries.
