ICacheTrigger represents a functional agent that allows to validate, reject or modify mutating operations against an underlying cache.

Namespace:  Tangosol.Net.Cache
Assembly:  Coherence (in Coherence.dll) Version: 14.1.1.14 (14.1.1.14)
Syntax
C#

public interface ICacheTrigger

The ICacheTrigger type exposes the following members.

Methods
  NameDescription
Public methodProcess
This method is called before the result of a mutating operation represented by the specified entry object is committed into the underlying cache.
Top
Remarks
The trigger operates on ICacheTriggerEntry object that represents a pending mutation that is about to be committed to the underlying cache. An ICacheTrigger could be registered with any IObservableCache using the CacheTriggerListener class:
Copy
INamedCache   cache   = CacheFactory.GetCache(cacheName);
ICacheTrigger trigger = new MyCustomTrigger();
cache.AddCacheListener(new CacheTriggerListener(trigger));
Note: In a clustered environment, ICacheTrigger registration process requires triggers to be serializable and providing a non-default implementation of the GetHashCode() and Equals() methods. Failure to do so may result in duplicate registration and a redundant entry processing by equivalent, but "not equal" ICacheTrigger objects.
