Examples of SyncCallback

org.chromium.sdk.SyncCallback
Secondary callback that should be called after main callback has been called; it gets called regardless of whether main callback finished normally or thrown an exception. It helps to separate callback logic (which may fail) from multi-thread synchronization (which shouldn't fail). Typically client may release his semaphore in this callback.
It could also be called 'finally callback', implying that is resembles try-finally control flow.
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.

Examples of org.voltdb.client.SyncCallback

        // if you want to test synchronous latency, this
        //  is a good variable to change
        boolean async = true;


        for (int i = 0; i < 100; i++) {
            SyncCallback cb = new SyncCallback();
            client.callProcedure(cb, "InsertO3", 3, i, i, i);


            if (!async) {
                cb.waitForResponse();
                VoltTable vt = cb.getResponse().getResults()[0];
                assertTrue(vt.getRowCount() == 1);
            }
        }
