Class ClearableIntObjectHashMap<VType>

java.lang.Object
com.carrotsearch.hppc.IntObjectHashMap<VType>
org.antlr.v4.runtime.atn.ClearableIntObjectHashMap<VType>
Type Parameters:
VType - value type
All Implemented Interfaces:
com.carrotsearch.hppc.Accountable, com.carrotsearch.hppc.IntObjectAssociativeContainer<VType>, com.carrotsearch.hppc.IntObjectMap<VType>, com.carrotsearch.hppc.Preallocable, Cloneable, Iterable<com.carrotsearch.hppc.cursors.IntObjectCursor<VType>>
final class ClearableIntObjectHashMap<VType> extends com.carrotsearch.hppc.IntObjectHashMap<VType>
Package-private int → V map with O(1) empty clear().

API boundary: Package-private only — used as a private field on ParserATNSimulator for the retained precedence-filter alt-1 index. Never appears in any public or protected signature. Extends HPPC so hot put/get stay monomorphic without a wrapper frame; HPPC is not part of the published API.

HPPC's stock IntObjectHashMap.clear() always bulk-fills the table. Retained scratch clears every filter invocation; empty clear is a no-op.
