Constructor Detail

ConnectionEvent

public ConnectionEvent(DataEngineConnection source,
                       int type)

Creates a new ConnectionEvent

Method Detail

getConnection

public DataEngineConnection getConnection()

Gets the connection associated with the event (this will be null only if the event is the creation or destruction of an entire connection pool).

getOriginatingEvent

public ConnectionEvent getOriginatingEvent()

Gets the event which caused this event (if such an event exists). For example, if this event type is CONNECTION_CREATE and the connection is being created because a different connection had timed out, then the originating event would be the CONNECTION_TIMEOUT event for the timeout. If the connection was instead created just because more connections were needed in the connection pool, then there would be no originating event.

getType

public int getType()

Gets the type of event that occured. This will be one of the constants defined in the class.
