A RegionService provides access to existing regions that exist in a Geode cache.
Regions can be obtained using getRegion and queried using getQueryService. The service should be closed to free up resources once it is no longer needed. Once it is closed any attempt to use it or any regions obtained from it will cause a CacheClosedException to be thrown.
Instances of the interface are created using one of the following methods:
| virtual void apache::geode::client::RegionService::close |
( |
| ) |
|
|
pure virtual |
Terminates this object cache and releases all the local resources.
After this cache is closed, any further method call on this cache or any region object will throw CacheClosedException, unless otherwise noted. If RegionService is created from Cache#createAuthenticatedView", then it clears user related security data.
- Parameters
-
| keepalive | whether to keep a durable CQ kept alive for this user. |
- Exceptions
-
| CacheClosedException,if | the cache is already closed. |

public methods
Indicates if this cache has been closed. After a new cache object is created, this method returns false; After the close is called on this cache object, this method returns true.
- Returns
- true, if this cache is closed; false, otherwise

| virtual void apache::geode::client::RegionService::rootRegions |
( |

regions | ) |
|
|
pure virtual |
Returns a set of root regions in the cache.
This set is a snapshot and is not backed by the Cache. The vector passed in is cleared and the regions are added to it.
