Puts a new value into an entry in this region with the specified key, passing the callback argument to any cache writers and cache listeners that are invoked in the operation.

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

Syntax

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

Parameters

key
CacheableKey
a key object associated with the value to be put into this region.
value
IGFSerializable
the value to be put into this region
callback
IGFSerializable
argument that is passed to the callback functions

Remarks

If there is already an entry associated with the specified key in this region, the entry's previous value is overwritten. The new put value is propogated to the java server to which it is connected with. Put is intended for very simple caching situations. In general it is better to create a ICacheLoader object and allow the cache to manage the creation and loading of objects.

Updates the LastAccessedTime and LastModifiedTime for this region and the entry.

If remote server put fails throwing back a CacheServerException or security exception, then local put is tried to rollback. However, if the entry has overflowed/evicted/expired then the rollback is aborted since it may be due to a more recent notification or update by another thread.

Exceptions

ExceptionCondition
GemStone.GemFire.Cache..::IllegalArgumentException if key is null
GemStone.GemFire.Cache..::CacheWriterException if CacheWriter aborts the operation
GemStone.GemFire.Cache..::CacheListenerException if CacheListener throws an exception
GemStone.GemFire.Cache..::RegionDestroyedException if region has been destroyed
GemStone.GemFire.Cache..::CacheServerException If an exception is received from the Java cache server. Only for Native Client regions.
GemStone.GemFire.Cache..::NotConnectedException if not connected to the GemFire system because the client cannot establish usable connections to any of the servers given to it.
GemStone.GemFire.Cache..::TimeoutException if the operation timed out
GemStone.GemFire.Cache..::OutOfMemoryException if there is not enough memory for the value
