[poky] [PATCH 1/4][Image Creator]Refactory Current Cache implementation
Ke Liping
liping.ke at intel.com
Tue May 31 01:15:57 PDT 2011
From: Liping Ke <liping.ke at intel.com>
This patch is for refactorying current cache implementation, the
main reason is for introducing extra cache fields requests for
image creator as well as other users. The refactory parts include:
Move cache data retrieve methods out of Cache Data Fields
Definition. Since this retrieve methods will be shared for
both CoreRecipeInfo as well as the new introduced extra RecipeInfo
in the following patches.
