Namespace: GemStone.GemFire.Cache
Assembly:  GemStone.GemFire.Cache (in GemStone.GemFire.Cache.dll)
Version: 2.7.0.1

Syntax

C#
public void Invalidate(
	CacheableKey key,
	IGFSerializable callback
)
Visual Basic (Declaration)
Public Sub Invalidate ( _
	key As CacheableKey, _
	callback As IGFSerializable _
)
Visual C++
public:
void Invalidate (

	IGFSerializable^ callback
)

Parameters

key
CacheableKey
key of the value to be invalidated
callback
IGFSerializable
a user-defined parameter to pass to callback events triggered by this method

Remarks

Invalidate only removes the value from the entry -- the key is kept intact. To completely remove the entry, call Destroy(ICacheableKey, IGFSerializable).

The invalidate is not propogated to the Gemfire cache server to which it is connected with.

Does not update any CacheStatistics.

Exceptions
