## org.mule.tck.functional
Class FunctionalStreamingTestComponent

    java.lang.Object
      org.mule.tck.functional.FunctionalStreamingTestComponent

All Implemented Interfaces:
  Callable, EventListener

    public class FunctionalStreamingTestComponent

extends Object
implements Callable

A service that can be used by streaming functional tests. This service accepts an EventCallback that can be used to assert the state of the current event. To access the service when embedded in an (XML) model, make sure that the descriptor sets the singleton attribute true - see uses in TCP and FTP. Note that although this implements the full StreamingService interface, nothing is written to the output stream - this is intended as a final sink.

Constructor Detail

### FunctionalStreamingTestComponent

    public FunctionalStreamingTestComponent()

Method Detail

### setEventCallback

    public void setEventCallback(EventCallback eventCallback,
                                 long targetSize)

### getSummary

    public String getSummary()

### getNumber

    public int getNumber()

### onCall

    public Object onCall(MuleEventContext context)
                  throws Exception

  Description copied from interface: `Callable`
  Passes the event to the listener

  Specified by:
    `onCall` in interface `Callable`
  Parameters:
    `context` - the context of the current event being process
  Returns:
    Object this object can be anything. When the `LifecycleAdapter` for the service receives this object it will first see if the Object is an `MuleMessage` if not and the Object is not null a new message will be created using the returned object as the payload. This new event will then get published via the configured outbound router if-
    1. One has been configured for the component.
    2. the `setStopFurtherProcessing(true)` wasn't called on the event context event.
  Throws:
    `Exception` - if the event fails to process properly. If exceptions aren't handled by the implementation they will be handled by the exceptionListener associated with the service

### read

    protected int read(InputStream in,
                       byte[] buffer)
                throws IOException

  Throws:
    `IOException`

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`
