Class PendingOperationTask

java.lang.Object

to.etc.webapp.pendingoperations.PendingOperationTask

All Implemented Interfaces:

Runnable, ILogSink

public final class PendingOperationTask
extends Object
implements Runnable, ILogSink

This is a runnable which tries to execute one or more PendingOperations. This only executes multiple PendingOperations if these operations belong to the same group. In that case it handles group state transitions in the database with all of the group records locked, to prevent multiserver trouble. If any of the PendingOperations fails the failed one is marked as such and scheduled for retry; all others in the group are released without being processed.
