## Class TSqlMapCacheModel

Description

TSqlMapCacheModel corresponds to the <cacheModel> sql mapping configuration tag.

The results from a query Mapped Statement can be cached simply by specifying the CacheModel property in <statement> tag. A cache model is a configured cache that is defined within the sql map configuration file. Cache models are configured using the <cacheModel> element.

The cache model uses a pluggable framework for supporting different types of caches. The choice of cache is specified by the Implementation property. The class name specified must be one of TSqlMapCacheTypes.

The cache implementations, LRU and FIFO cache below do not persist across requests. That is, once the request is complete, all cache data is lost. These caches are useful queries that results in the same repeated data during the current request.
