com.mchange.v2.encounter.EqualityEncounterCounter

All Implemented Interfaces:

EncounterCounter

public class EqualityEncounterCounter
extends Object

Deprecated.

-- Use of WeakHashMap can't properly guarantee counts with equality semantics, as an Object can be encounted garbage collected, then re-encountered with no apparent history. Clients should explicit choose the semantics they want via WeakEqualityEncounterCounter or StrongEqualityEncounterCounter
