Examples with StateInternalsProxy org.apache.beam.runners.apex.translation.utils.StateInternalsProxy used on opensource projects

Example 1 with StateInternalsProxy

use of org.apache.beam.runners.apex.translation.utils.StateInternalsProxy in project beam by apache.

the class ApexParDoOperator method fireTimer.

@Override
public void fireTimer(Object key, Collection<TimerData> timerDataSet) {
    pushbackDoFnRunner.startBundle();
    @SuppressWarnings("unchecked") Coder<Object> keyCoder = (Coder) currentKeyStateInternals.getKeyCoder();
    ((StateInternalsProxy) currentKeyStateInternals).setKey(key);
    currentKeyTimerInternals.setContext(key, keyCoder, new Instant(this.currentInputWatermark), new Instant(this.currentOutputWatermark));
    for (TimerData timerData : timerDataSet) {
        StateNamespace namespace = timerData.getNamespace();
        checkArgument(namespace instanceof WindowNamespace);
        BoundedWindow window = ((WindowNamespace<?>) namespace).getWindow();
        pushbackDoFnRunner.onTimer(timerData.getTimerId(), window, timerData.getTimestamp(), timerData.getDomain());
    }
    pushbackDoFnRunner.finishBundle();
}
