      Returns the behavior of a plural attribute container if the attribute is plural, or null otherwise.
      Returns:
      The container behavior, or null if attribute is singular

    • setContainerDefault

      void setContainerDefault()
      Sets the container behavior to EntityViewAttributeMapping.ContainerBehavior.DEFAULT.
