  org.eclipse.smila.jobmanager.internal.DefinitionPersistenceImpl

All Implemented Interfaces:

DefinitionPersistence

public class DefinitionPersistenceImpl
extends java.lang.Object
implements DefinitionPersistence

Handles read/write operations of jobmanager definitions. Write operations are handled directly by writing to internal store after validating them. Read operations are delegated to DefinitionAccessor.
