private static final class PredictionContextCache.ChildKeyProbe extends PredictionContextCache.ChildKey
Mutable probe for PredictionContextCache.getChild(org.antlr.v4.runtime.atn.PredictionContext, int) lookups. Package-private and not a PredictionContextCache.PredictionContextAndInt, so it cannot be passed to Map.put(K, V) on Map<ChildKey, …> only through an erroneous cast — and the cache never exposes the map.
