SDMCache

The SDMCache is a programming interface that provides in-memory cache for quick data access. Its APIs allow adding, removing and searching items stored in the cache. The cache also acts as a central, shared storage, avoiding the need to pass frequently used data between view controllers.

List of Features

In-memory management of SDMOData-related objects
Quick data filtering
Prefix matching and regular expression support (default search method is prefix matching)
