      • writeBatch

        public void writeBatch​(java.lang.Iterable<MarshalledEntry<? extends K,​? extends V>> marshalledEntries)
        Description copied from interface: CacheWriter
        Persist all provided entries to the store in a single batch update. If this is not supported by the underlying store, then entries are written to the store individually via CacheWriter.write(MarshalledEntry).
        Specified by:
        writeBatch in interface CacheWriter<K,​V>
        Parameters:
        marshalledEntries - an Iterable of MarshalledEntry to be written to the store.
      • deleteBatch

        public void deleteBatch​(java.lang.Iterable<java.lang.Object> keys)
        Description copied from interface: CacheWriter
        Remove all provided keys from the store in a single batch operation. If this is not supported by the underlying store, then keys are removed from the store individually via CacheWriter.delete(Object).
        Specified by:
        deleteBatch in interface CacheWriter<K,​V>
        Parameters:
        keys - an Iterable of entry Keys to be removed from the store.
      • delete

        public boolean delete​(java.lang.Object key)
        Specified by:
        delete in interface CacheWriter<K,​V>
        Returns:
        true if the entry existed in the persistent store and it was deleted.

        Description copied from interface: AdvancedCacheWriter
        Using the thread in the pool, removed all the expired data from the persistence storage. For each removed entry, the supplied listener is invoked.

        When this method returns all entries will be purged and no tasks will be running due to this loader in the provided executor. If however an exception is thrown there could be tasks still pending or running in the executor.
