Syntax

public void Invalidate(
	ICacheableKey key
)

Public Sub Invalidate ( 
	key As ICacheableKey
)

public:
void Invalidate(
	ICacheableKey^ key
)

member Invalidate : 
        key : ICacheableKey -> unit

key: Type: GemStone.GemFire.CacheICacheableKey
key of the value to be invalidated

Exceptions

Exception	Condition
IllegalArgumentException	if key is null
EntryNotFoundException	if this entry does not exist in this region locally
RegionDestroyedException	if the region is destroyed

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.
