java.lang.Object

org.opendaylight.yangtools.yang.data.util.EmptyConstraintDefinition

All Implemented Interfaces:

ConstraintDefinition

public abstract class EmptyConstraintDefinition
extends Object
implements ConstraintDefinition

Utility holder for constraint definitions which do not really constrain anything.

Method Detail

create

public static EmptyConstraintDefinition create(boolean mandatory)

getWhenCondition

public final RevisionAwareXPath getWhenCondition()

Description copied from interface: ConstraintDefinition

Specifies the condition when the data node which contains when YANG substatement has to be present. If XPath expression is evaluated as true then the data node has to be present.

Specified by:

getWhenCondition in interface ConstraintDefinition

Returns:

XPath expression.

getMustConstraints

public final Set<MustDefinition> getMustConstraints()

Description copied from interface: ConstraintDefinition

Specifies the rules which the node which contains must YANG substatement has to match.

Specified by:

getMustConstraints in interface ConstraintDefinition

Returns:

set of MustDefinition (XPath) instances which represents the concrete data constraints

getMinElements

public final Integer getMinElements()

Description copied from interface: ConstraintDefinition

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.

Specified by:

getMinElements in interface ConstraintDefinition

Returns:

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

getMaxElements

public final Integer getMaxElements()

Description copied from interface: ConstraintDefinition

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.

Specified by:

getMaxElements in interface ConstraintDefinition

Returns:

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

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

toString

public final String toString()

Overrides:

toString in class Object
