Interface ICacheEventTransformer

ICacheEventTransformer interface is used to allow an event consumer to change the content of a CacheEventArgs destined for the corresponding ICacheListener.

Namespace: Tangosol.Net.Cache

Assembly: Coherence.dll

Syntax

public interface ICacheEventTransformer

Remarks

In general, the Transform(CacheEventArgs) method is called after the original CacheEventArgs is evaluated by an IFilter (such as CacheEventFilter). The values contained by the returned CacheEventArgs object will be the ones given (sent) to the corresponding listener. Returning null will prevent the emission of the event altogether.

Note: Currently, the ICacheEventTransformer interface is supported only by partitioned caches.
