ObjectGrid interface
The following methods allow you to interact with an ObjectGrid instance.
BackingMap interface
Each ObjectGrid instance contains a collection of BackingMap objects. Use the defineMap method or the createMap method of the ObjectGrid interface to name and add each BackingMap to an ObjectGrid instance. These methods return a BackingMap instance that is then used to define the behavior of an individual Map. A BackingMap can be considered as an in-memory cache of committed data for an individual map.
ExceptionMapper interface
When a user plug-in implementation throws an exception, eXtreme Scale checks certain exceptions defined in the throws contract. However, sometimes an unchecked exception contains a contract exception or the exception does not observe the contract appropriately. Therefore a mechanism is necessary to map the exception to the contract exception if possible, such as ExceptionMapper.
Regular expression syntax
A regular expression is a structured string that is used to match other strings. You can use regular expressions for data invalidation and for filtering the messages that display in the message center.
Configuration files
WebSphere eXtreme Scale is configured by a collection of XML and properties files.
Messages
When you encounter a message in a log or other parts of the product interface, you can look up the message by its component prefix to find out more information.
User interface settings
This reference information describes settings that you can view and configure on the pages of the WebSphere Application Serveradministrative console and elsewhere.
