score::SelectionStack::Batch Class Reference

Detailed Description

While a batch is open, prune() only records the destroyed object. The stack is swept once when the outermost batch ends, with a single currentSelectionChanged: destroying k selected objects out of n costs O(n) instead of O(k * n).

Inside a batch, the stack may still hold the recorded objects until the next mutation (push, unselect, ...), which sweeps first; currentSelection() already leaves them out.
