Enum Class ClientRegionShortcut
- All Implemented Interfaces:
Serializable,Comparable<ClientRegionShortcut>,Constable
Each enum represents a predefined
RegionAttributes in a ClientCache. These enum
values can be used to create regions using a ClientRegionFactory obtained by calling
ClientCache.createClientRegionFactory(ClientRegionShortcut).
Another way to use predefined region attributes is in cache.xml by setting the refid attribute on a region element or region-attributes element to the string of each value.

-
PROXY
A PROXY region has no local state and forwards all operations to a server. The actual RegionAttributes for a PROXY set theDataPolicytoDataPolicy.EMPTY. -
CACHING_PROXY
A CACHING_PROXY region has local state but can also send operations to a server. If the local state is not found then the operation is sent to the server and the local state is updated to contain the server result. The actual RegionAttributes for a CACHING_PROXY set theDataPolicytoDataPolicy.NORMAL. -
CACHING_PROXY_HEAP_LRU
A CACHING_PROXY_HEAP_LRU region has local state but can also send operations to a server. If the local state is not found then the operation is sent to the server and the local state is updated to contain the server result. It will also destroy entries once it detects that the java vm is running low of memory. The actual RegionAttributes for a CACHING_PROXY_HEAP_LRU set theDataPolicytoDataPolicy.NORMAL. andEvictionAttributesare set toEvictionAlgorithm.LRU_HEAPwithEvictionAction.LOCAL_DESTROY. -
CACHING_PROXY_OVERFLOW
A CACHING_PROXY_OVERFLOW region has local state but can also send operations to a server. If the local state is not found then the operation is sent to the server and the local state is updated to contain the server result. It will also move the values of entries to disk once it detects that the java vm is running low of memory. The actual RegionAttributes for a CACHING_PROXY_OVERFLOW set theDataPolicytoDataPolicy.NORMAL. andEvictionAttributesare set toEvictionAlgorithm.LRU_HEAPwithEvictionAction.OVERFLOW_TO_DISK. -
LOCAL
A LOCAL region only has local state and never sends operations to a server. The actual RegionAttributes for a LOCAL region set theDataPolicytoDataPolicy.NORMAL. -
LOCAL_PERSISTENT
A LOCAL_PERSISTENT region only has local state and never sends operations to a server but it does write its state to disk and can recover that state when the region is created. The actual RegionAttributes for a LOCAL_PERSISTENT region set theDataPolicytoDataPolicy.PERSISTENT_REPLICATE. -
LOCAL_HEAP_LRU
A LOCAL_HEAP_LRU region only has local state and never sends operations to a server. It will also destroy entries once it detects that the java vm is running low of memory. The actual RegionAttributes for a LOCAL_HEAP_LRU region set theDataPolicytoDataPolicy.NORMALandEvictionAttributesare set toEvictionAlgorithm.LRU_HEAPwithEvictionAction.LOCAL_DESTROY. -
LOCAL_OVERFLOW
A LOCAL_OVERFLOW region only has local state and never sends operations to a server. It will also move the values of entries to disk once it detects that the java vm is running low of memory. The actual RegionAttributes for a LOCAL_OVERFLOW region set theDataPolicytoDataPolicy.NORMALandEvictionAttributesare set toEvictionAlgorithm.LRU_HEAPwithEvictionAction.OVERFLOW_TO_DISK. -
LOCAL_PERSISTENT_OVERFLOW
A LOCAL_PERSISTENT_OVERFLOW region only has local state and never sends operations to a server but it does write its state to disk and can recover that state when the region is created. It will also remove the values of entries from memory once it detects that the java vm is running low of memory. The actual RegionAttributes for a LOCAL_PERSISTENT_OVERFLOW region set theDataPolicytoDataPolicy.PERSISTENT_REPLICATEandEvictionAttributesare set toEvictionAlgorithm.LRU_HEAPwithEvictionAction.OVERFLOW_TO_DISK.
