Example 29 with EventRegistration

use of com.hazelcast.spi.EventRegistration in project hazelcast by hazelcast.

the class BatchInvalidator method sendInvalidations.

private void sendInvalidations(String dataStructureName, List<Invalidation> invalidations) {
    // There will always be at least one listener which listens invalidations. This is the reason behind eager creation
    // of BatchNearCacheInvalidation instance here. There is a causality between listener and invalidation. Only if we have
    // a listener, we can have an invalidation, otherwise invalidations are not generated.
    Invalidation invalidation = new BatchNearCacheInvalidation(dataStructureName, invalidations);

    for (EventRegistration registration : registrations) {

            // find worker queue of striped executor by using subscribers' address.

            // the same workers queue.
