HidingMap
Description
Initializes the hiding map with an optional default value, defaulting to false (not hidden).
The map stores flags coerced to booleans, so a write of an unchanged flag is provably a no-op —
skipUnchangedWrites is always on, keeping no-op writes from rebuilding the index caches.
Methods
getHiddenIndexes
hidingMap.getHiddenIndexes() ⇒ Array
Get physical indexes which are hidden.
Note: Indexes marked as hidden are included in a DataMap, but aren’t rendered.
