    • detach

      public boolean detach()
      Description copied from interface: ORecord
      Removes all the dependencies with other records. All the relationships remain in form of RecordID. If some links contain dirty records, the detach cannot be complete and this method returns false.
      Specified by:
      detach in interface ORecord
      Returns:
      True if the document has been successfully detached, otherwise false.

    • clear

      public ORecordAbstract clear()
      Description copied from interface: ORecord
      All the fields are deleted but the record identity is maintained. Use this to remove all the document's fields.
      Specified by:
      clear in interface ORecord
      Returns:
      The Object instance itself giving a "fluent interface". Useful to call multiple methods in chain.

    • reset

      public ORecordAbstract reset()

      Specified by:
      reset in interface ORecord
      Returns:
      The Object instance itself giving a "fluent interface". Useful to call multiple methods in chain.
