org.opendaylight.yangtools.yang.model.api.ElementCountConstraint
@Beta public abstract class ElementCountConstraint extends Object
Contains method which returns various data constraints for a list-like YANG element (e.g. min or max number of elements).

  • Method Details

    • atLeast

      public static @NonNull ElementCountConstraint atLeast(int minElements)

    • atMost

      public static @NonNull ElementCountConstraint atMost(int maxElements)

    • inRange

      public static @NonNull ElementCountConstraint inRange(int minElements, int maxElements)

    • forNullable

      public static @NonNull Optional<ElementCountConstraint> forNullable(@Nullable Integer minElements, @Nullable Integer maxElements)

    • getMinElements

      public abstract @Nullable Integer getMinElements()
      Returns the minimum required number of data elements for node where this constraint is specified.

      The returning value equals to value of the argument of the min-elements YANG substatement. It is used with YANG statements leaf-list, list, deviate.

      Returns:
      integer with minimal number of elements, or null if no minimum is defined

    • getMaxElements

      public abstract @Nullable Integer getMaxElements()
      Returns the maximum admissible number of data elements for node where this constraint is specified.

      The returning value equals to value of the argument of the max-elements YANG substatement. It is used with YANG statements leaf-list, list, deviate.

      Returns:
      integer with maximum number of elements, or null if no maximum is defined
