All Implemented Interfaces:

DataObjectConstructionDetails, EntityInfo, Exemptible

public abstract class DataObjectForTermReplacement
extends DataObjectReadOnlyWithCache

Data object with cache - special case most of the case nothing can be found. Therefore, multiple accesses without success are avoided via caching of 'not available'.
