Modifier and Type	Method and Description
String	invalidates(ValidityContext<? extends org.apache.isis.applib.events.ValidityEvent> context) Whether the validation represented by this facet passes or fails.
boolean	isInvertedSemantics() Indicates that the implementation is overridding the usual semantics, in other words that the FacetHolder to which this Facet is attached is not mandatory.
boolean	isRequiredButNull(ObjectAdapter adapter) If not specified or, if a string, then zero length.

type

public static Class<? extends Facet> type()

isRequiredButNull

public final boolean isRequiredButNull(ObjectAdapter adapter)

If not specified or, if a string, then zero length.

Specified by:

isRequiredButNull in interface MandatoryFacet

isInvertedSemantics

public boolean isInvertedSemantics()

Description copied from interface: MandatoryFacet

Indicates that the implementation is overridding the usual semantics, in other words that the FacetHolder to which this Facet is attached is not mandatory.

Specified by:

isInvertedSemantics in interface MandatoryFacet

invalidates

public String invalidates(ValidityContext<? extends org.apache.isis.applib.events.ValidityEvent> context)

Description copied from interface: ValidatingInteractionAdvisor

Whether the validation represented by this facet passes or fails.

Implementations should use the provided ValidityContext to determine whether they declare the interaction invalid. They must however guard against a null target and session - neither are guaranteed to be populated.

Specified by:

invalidates in interface ValidatingInteractionAdvisor
