Syntax

struct FSlateCachedElementData

Remarks

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
