Examples of org.voltdb.client.SyncCallback

org.voltdb.client.SyncCallback
A utility class that allows a client to queue a stored procedure invocation asynchronously and then poll or join on the response. Useful when invoking multiple stored procedures synchronously from a single thread. Queue each of the invocations asynchronously with a different SyncCallback and then call {@link #waitForResponse} on each of the SyncCallbacks to join on the responses.
