Method Details

buildElementInfo
Builds up info about each element in a region.- Specified by:
buildElementInfoin interfaceJCSJMXBean- Parameters:
cacheName-- Returns:
- List of CacheElementInfo objects
- Throws:
IOException
-
buildCacheInfo
Builds up data on every region.TODO we need a most light weight method that does not count bytes. The byte counting can really swamp a server.
- Specified by:
buildCacheInfoin interfaceJCSJMXBean- Returns:
- List of CacheRegionInfo objects
-
getByteCount
Tries to estimate how much data is in a region. This is expensive. If there are any non serializable objects in the region or an error occurs, suppresses exceptions and returns 0.- Specified by:
getByteCountin interfaceJCSJMXBean- Returns:
- int The size of the region in bytes.
-
getByteCount
Tries to estimate how much data is in a region. This is expensive. If there are any non serializable objects in the region or an error occurs, suppresses exceptions and returns 0.- Returns:
- int The size of the region in bytes.
-
clearAllRegions
Clears all regions in the cache.If this class is running within a remote cache server, clears all regions via the
RemoteCacheServerAPI, so that removes will be broadcast to client machines. Otherwise clears all regions in the cache directly via the usual cache API.- Specified by:
clearAllRegionsin interfaceJCSJMXBean- Throws:
IOException
-
clearRegion
Clears a particular cache region.If this class is running within a remote cache server, clears the region via the
RemoteCacheServerAPI, so that removes will be broadcast to client machines. Otherwise clears the region directly via the usual cache API.- Specified by:
clearRegionin interfaceJCSJMXBean- Throws:
IOException
-
removeItem
Removes a particular item from a particular region.If this class is running within a remote cache server, removes the item via the
RemoteCacheServerAPI, so that removes will be broadcast to client machines. Otherwise clears the region directly via the usual cache API.- Specified by:
removeItemin interfaceJCSJMXBean- Parameters:
cacheName-key-- Throws:
IOException
