Detailed Description

Top level class responsible for cached elements within a particular invalidation root. Equivalent to the plain FSlateBatchData in that it manages multiple renderbatches, element lists (Per widget), & new element lists (Per invalidated widgets).

Note: Just as each window may have multiple invalidation roots, each window element list may have multiple 'FSlateCachedElementData' for each root

AddCache()

FSlateCachedElementsHandle FSlateCachedElementData::AddCache

(

const SWidget *

Widget

)

Create a new CachedElementList, occurs when adding a cached element whose top level draw widget is not already part of some cache

AddCachedElement()

template<EElementType ElementType>
