containsFacet

public boolean containsFacet(java.lang.Class<? extends Facet> facetType)

Description copied from interface: FacetHolder

Whether there is a facet registered of the specified type.

Convenience; saves having to FacetHolder.getFacet(Class) and then check if null.

Specified by:

addFacet

public void addFacet(Facet facet)

Description copied from interface: FacetHolder

Adds the facet, extracting its type as the key.

If there are any facet of the same type, they will be overwritten provided that either the Facet specifies to always replace or if the existing Facet is a no-op.

Specified by:

addFacet

public void addFacet(MultiTypedFacet facet)

Description copied from interface: FacetHolder

Adds the multi-typed facet, extracting each of its types as keys.

If there are any facet of the same type, they will be overwritten provided that either the Facet specifies to always replace or if the existing Facet is a no-op.

Specified by:

removeFacet

public void removeFacet(Facet facet)

Description copied from interface: FacetHolder

Remove the facet whose type is that reported by Facet.facetType().

Specified by:

getFacet

public <T extends Facet> T getFacet(java.lang.Class<T> facetType)

Description copied from interface: FacetHolder

Get the facet of the specified type (as per the type it reports from Facet.facetType()).

Specified by:

getFacet in interface FacetHolder

getFacetTypes

public java.lang.Class<? extends Facet>[] getFacetTypes()

Description copied from interface: FacetHolder

Get the list of all facet types that are supported by objects of this specification.

Specified by:

getFacetTypes in interface FacetHolder
