Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Drop one side of a compound boolean: a && b becomes a and b, and the same for || (both the symbol and the and / or keyword forms).

BooleanOperatorReplacement swaps the operator but always keeps both operands, so a test that only ever exercises one side of a condition survives it. Promoting an operand kills exactly those tests.
