Class AbstractCacheEventFilterConverter<K,V,C>

java.lang.Object

org.infinispan.notifications.cachelistener.filter.AbstractCacheEventFilterConverter<K,V,C>

All Implemented Interfaces:

CacheEventConverter<K,V,C>, CacheEventFilter<K,V>, CacheEventFilterConverter<K,V,C>

Direct Known Subclasses:

IckleCacheEventFilterConverter, IckleContinuousQueryCacheEventFilterConverter

public abstract class AbstractCacheEventFilterConverter<K,V,C>
extends Object
implements CacheEventFilterConverter<K,V,C>

This is a base class that should be used when implementing a CacheEventFilterConverter that provides default implementations for the CacheEventFilter.accept(Object, Object, org.infinispan.metadata.Metadata, Object, org.infinispan.metadata.Metadata, EventType) and Converter.convert(Object, Object, org.infinispan.metadata.Metadata) methods so they just call the CacheEventFilterConverter.filterAndConvert(Object, Object, org.infinispan.metadata.Metadata, Object, org.infinispan.metadata.Metadata, EventType) method and then do the right thing.

Since:

7.0
