    • getClassInfo

      public static CDOClassInfo getClassInfo(EClass eClass)
      Returns additional CDO infos for an EClass.

      This operation is somewhat expensive because it synchronizes on the EClass and iterates over all adapters. Whenever possible use CDORevision.getClassInfo() or InternalCDOObject.getClassInfo().

      @Deprecated public static EStructuralFeature[] getAllPersistentFeatures(EClass eClass)
      Deprecated.
      As of 4.2 use CDOModelUtil.getClassInfo(eClass).getAllPersistentFeatures().
      Returns all persistent features of an EClass.

      This operation is somewhat expensive because it synchronizes on the EClass and iterates over all adapters.
