Examples with TombstoneUpdate org.hibernate.cache.infinispan.util.TombstoneUpdate used on opensource projects

Example 1 with TombstoneUpdate

use of org.hibernate.cache.infinispan.util.TombstoneUpdate in project hibernate-orm by hibernate.

the class TombstoneAccessDelegate method putFromLoad.

@Override
public boolean putFromLoad(SharedSessionContractImplementor session, Object key, Object value, long txTimestamp, Object version, boolean minimalPutOverride) throws CacheException {
    long lastRegionInvalidation = region.getLastRegionInvalidation();
    if (txTimestamp < lastRegionInvalidation) {
        log.tracef("putFromLoad not executed since tx started at %d, before last region invalidation finished = %d", txTimestamp, lastRegionInvalidation);
        return false;
    }
    if (minimalPutOverride) {
        Object prev = cache.get(key);
        if (prev instanceof Tombstone) {
            Tombstone tombstone = (Tombstone) prev;
            long lastTimestamp = tombstone.getLastTimestamp();

            return false;
        }
    }
    // we can't use putForExternalRead since the PFER flag means that entry is not wrapped into context
    // when it is present in the container. TombstoneCallInterceptor will deal with this.
    putFromLoadCache.put(key, new TombstoneUpdate(session.getTimestamp(), value));
    return true;
}

Example 2 with TombstoneUpdate

use of org.hibernate.cache.infinispan.util.TombstoneUpdate in project hibernate-orm by hibernate.
