org.camunda.bpm.engine.impl.db.entitymanager.cache.DbEntityCacheKeyMapping

public class DbEntityCacheKeyMapping
extends java.lang.Object

Provides the keys used by DbEntityCache for organizing the different DbEntity types. Especially for polymorphic types, it is important that they are accessible in the cache under one common key such that querying the cache with a superclass or with a subclass both return the cached entities.
