Class ERMemoryAdaptorContext

java.lang.Object
  com.webobjects.eoaccess.EOAdaptorContext
      er.memoryadaptor.ERMemoryAdaptorContext

public class ERMemoryAdaptorContext
extends com.webobjects.eoaccess.EOAdaptorContext

ERMemoryAdaptorContext provides the adaptor context implementation for ERMemoryAdaptor. For the most part, you don't need to interact with ERMemoryAdaptor at this level. However, the context does expose resetEntity(EOEntity) and resetAllEntities() methods which allow control over resetting the memory datastore. This can be helpful when you need to reset the "database" between test cases.
