DomainObjectCollection

interface DomainObjectCollection<T> : Collection<E> (source)

A DomainObjectCollection is a specialised Collection that adds the ability to receive modification notifications and use live filtered sub collections.

The filtered collections returned by the filtering methods, such as matching, return collections that are live. That is, they reflect changes made to the source collection that they were created from. This is true for filtered collections made from filtered collections etc.

You can also add actions that are executed as elements are added to the collection. Actions added to filtered collections will be fired if an addition/removal occurs for the source collection that matches the filter.

DomainObjectCollection instances are not thread-safe and undefined behavior may result from the invocation of any method on a collection that is being mutated by another thread; this includes direct invocations, passing the collection to a method that might perform invocations, and using an existing iterator to examine the collection.

inline fun <S : Any> DomainObjectCollection<in S>.withType(): DomainObjectCollection<S>

Returns a collection containing the objects in this collection of the given type. The returned collection is live, so that when matching objects are later added to this collection, they are also visible in the filtered collection.

inline fun <S : Any> DomainObjectCollection<in S>.withType(noinline configuration: S.() -> Unit): DomainObjectCollection<S>

Returns a collection containing the objects in this collection of the given type. Equivalent to calling withType(type).all(configureAction).

inline fun <S : T, T : Any> DomainObjectCollection<T>.withType(type: KClass<S>): DomainObjectCollection<S>
inline fun <S : T, T : Any> DomainObjectCollection<T>.withType(type: KClass<S>, configureAction: Action<in S>): DomainObjectCollection<S>
