Constructor Detail

DataExceptionEvent

public DataExceptionEvent(java.lang.Object source,
                          int id,
                          java.lang.Throwable cause,
                          DataExceptionEvent.SeverityType type)

Creates an event with an exception or warning to be carried over to the clients. This event is raised by an active data datacontrol when it cannot provide DataExceptionEntries anymore for example when the network connection is lost between a datacontrol and it's server or when the datacontrol's server is down or the message queue from which datacontrol was picking messages to process is down etc.

Parameters:

source - the publisher of the event.

id - Event Identifier generated by the datacontrol. This will be carried through to the component so that component may request datacontrol to start events from the given id onwards.

cause - Exception object containing an error or warning indicating the cause of the error. Note that this error may be recoverable

type - One of the SeverityType to indicate the severity of this error.
