Examples of voldemort.store.routed.Pipeline

voldemort.store.routed.Pipeline
A Pipeline is the main conduit through which an {@link Action} is run. An{@link Action} is executed in response to the Pipeline receiving an event.The majority of the events are self-initiated from within the Pipeline itself. The only case thus-far where external entities create events are in response to asynchronous responses from servers. A {@link Response} instanceis created on completion of an asynchronous request and is fed back into the Pipeline where an appropriate 'response handler' action is executed.
A Pipeline instance is created per-request inside {@link RoutedStore}. This is due to the fact that it includes internal state, specific to each operation request (get, getAll, getVersions, put, and delete) invocation.
