Examples of MandatoryFacet

org.apache.isis.core.metamodel.facets.mandatory.MandatoryFacet
Whether a property or a parameter is mandatory (not optional).
For a mandatory property, the object cannot be saved/updated without the value being provided. For a mandatory parameter, the action cannot be invoked without the value being provided.
In the standard Apache Isis Programming Model, specify mandatory by omitting the @Optional annotation.
