public interface NamedDomainObjectContainer<T> extends NamedDomainObjectSet<T>, org.gradle.util.Configurable<NamedDomainObjectContainer<T>>

A named domain object container is a specialisation of NamedDomainObjectSet that adds the ability to create instances of the element type.

Implementations may use different strategies for creating new object instances.

Note that a container is an implementation of SortedSet, which means that the container is guaranteed to only contain elements with unique names within this container. Furthermore, items are ordered by their name.
