Examples of com.atomikos.datasource.RecoverableResource.recover()

com.atomikos.datasource.RecoverableResource.recover()
Recovers the partially reconstructed Participant. @param participant A partially recovered Participant. @exception ResourceException On failure. @return boolean True iff reconstruction was successful.If the resource is not responsible for the given participant, then this will return false. A Participant can use this to iterate over all resources in order to eventually recover itself. This is particularly useful if the Participant instance can not serialize its full state, because some of it is on its backside resource (as, for instance, in XA). This way, the TransactionalResource can be used to assist in reconstruction of the Participant's state.
