getObjectGrid methods
Use the ObjectGridManager.getObjectGrid methods to retrieve cached instances.
Retrive a cached instance
Since the Employees ObjectGrid instance was cached by the ObjectGridManager interface, another user can access it with the following code snippet:
ObjectGrid myEmployees = oGridManager.getObjectGrid("Employees");
The following are the two getObjectGrid methods that return cached ObjectGrid instances:
- Retrive all cached instances
To obtain all of the ObjectGrid instances that have been previously cached, use the getObjectGrids method, which returns a list of each instance. If no cached instances exist, the method will return null.
- Retrive a cached instance by name
To obtain a single cached instance of an ObjectGrid, use getObjectGrid(String objectGridName), passing the name of the cached instance into the method. The method either returns the ObjectGrid instance with the specified name or returns null if there is no ObjectGrid instance with that name.
You can also use the getObjectGrid method to connect to a distributed grid. See Connect to a distributed ObjectGrid for more information.
