@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 Detail

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

hashCode

equals
