Class EngineCounters

Defines the constants that specifies the counter logic to be used within the engine. If you have large datasource and need support for groups and filtered records you can reduce the memory footprint by selectively disabling counters you do not need in your application. See WithoutCounter for completely disabling counter logic for the RecordsDetails collection and VirtualMode for using the engine in a virtual mode.
