Subject: [coco] Add 'PtrList<T>' class (#691)
X-Git-Tag: nncc_backup~2396
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dcf65043c4e746f7de4f295b6983e20a8853fcdf;p=platform%2Fcore%2Fml%2Fnnfw.git

[coco] Add 'PtrList<T>' class (#691)

Coco IR often uses a list of object pointers. To reduce code
duplication, this commit introduces 'PtrList<T>' helper class
which manages a list of object pointers (using std::vector).
