clsImageCache is a caching wrapper BOF business object for image data. Its specific caching strategy and public member surface were not fully described in the Phase 1 analysis*.

Purpose¶

Acts as a caching layer for image data within the BOF imaging library*.

Context¶

Namespace: SAIF.Business.Imaging
Assembly/package: SAIF.BOF.Business.Imaging
