Examples of CollectionFacet

org.apache.isis.core.metamodel.facets.collections.modify.CollectionFacet
Attached to {@link ObjectSpecification}s that represent a collection.
Factories of (implementations of this) facet should ensure that a {@link TypeOfFacet} is also attached to the same facet holder. The{@link #getTypeOfFacet()} is a convenience for this.
