public interface DomainObjectCollection<T> extends java.util.Collection<T>A
DomainObjectCollectionis a specialisedCollectionthat adds the ability to receive modification notifications and use live filtered sub collections.The filtered collections returned by the filtering methods, such as
matching(Closure), 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.
DomainObjectCollectioninstances 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.

Method Detail
-
addLater
void addLater(Provider<? extends T> provider)
Adds an element to this collection, given aProviderthat will provide the element when required.- Parameters:
provider- AProviderthat can provide the element when required.- Since:
- 4.8
-
addAllLater
void addAllLater(Provider<? extends java.lang.Iterable<T>> provider)
Adds elements to this collection, given aProviderofIterablethat will provide the elements when required.- Parameters:
provider- AProviderofIterablethat can provide the elements when required.- Since:
- 5.0
-
withType
<S extends T> DomainObjectCollection<S> withType(java.lang.Class<S> type)
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.- Parameters:
type- The type of objects to find.- Returns:
- The matching objects. Returns an empty collection if there are no such objects in this collection.
-
withType
<S extends T> DomainObjectCollection<S> withType(java.lang.Class<S> type, Action<? super S> configureAction)
Returns a collection containing the objects in this collection of the given type. Equivalent to callingwithType(type).all(configureAction)- Parameters:
type- The type of objects to find.configureAction- The action to execute for each object in the resulting collection.- Returns:
- The matching objects. Returns an empty collection if there are no such objects in this collection.
-
withType
<S extends T> DomainObjectCollection<S> withType(java.lang.Class<S> type, @DelegatesTo(genericTypeIndex=0) Closure configureClosure)
Returns a collection containing the objects in this collection of the given type. Equivalent to callingwithType(type).all(configureClosure).- Parameters:
type- The type of objects to find.configureClosure- The closure to execute for each object in the resulting collection.- Returns:
- The matching objects. Returns an empty collection if there are no such objects in this collection.
-
matching
DomainObjectCollection<T> matching(Spec<? super T> spec)
Returns a collection which contains the objects in this collection which meet the given specification. The returned collection is live, so that when matching objects are added to this collection, they are also visible in the filtered collection.- Parameters:
spec- The specification to use.- Returns:
- The collection of matching objects. Returns an empty collection if there are no such objects in this collection.
-
matching
DomainObjectCollection<T> matching(Closure spec)
Returns a collection which contains the objects in this collection which meet the given closure specification. The returned collection is live, so that when matching objects are added to this collection, they are also visible in the filtered collection.- Parameters:
spec- The specification to use. The closure gets a collection element as an argument.- Returns:
- The collection of matching objects. Returns an empty collection if there are no such objects in this collection.
-
whenObjectAdded
Action<? super T> whenObjectAdded(Action<? super T> action)
Adds anActionto be executed when an object is added to this collection.Like
all(Action), this method will cause all objects in this container to be realized.- Parameters:
action- The action to be executed- Returns:
- the supplied action
-
whenObjectAdded
void whenObjectAdded(Closure action)
Adds a closure to be called when an object is added to this collection. The newly added object is passed to the closure as the parameter.- Parameters:
action- The closure to be called- See Also:
whenObjectAdded(Action)
-
whenObjectRemoved
Action<? super T> whenObjectRemoved(Action<? super T> action)
Adds anActionto be executed when an object is removed from this collection.- Parameters:
action- The action to be executed- Returns:
- the supplied action
-
whenObjectRemoved
void whenObjectRemoved(Closure action)
Adds a closure to be called when an object is removed from this collection. The removed object is passed to the closure as the parameter.- Parameters:
action- The closure to be called
-
all
void all(Action<? super T> action)
Executes the given action against all objects in this collection, and any objects subsequently added to this collection.- Parameters:
action- The action to be executed
-
all
void all(Closure action)
Executes the given closure against all objects in this collection, and any objects subsequently added to this collection. The object is passed to the closure as the closure delegate. Alternatively, it is also passed as a parameter.- Parameters:
action- The action to be executed
-
configureEach
void configureEach(Action<? super T> action)
Configures each element in this collection using the given action, as each element is required. Actions are run in the order added.- Parameters:
action- AActionthat can configure the element when required.- Since:
- 4.9
-
findAll
java.util.Collection<T> findAll(Closure spec)
Returns a collection which contains the objects in this collection which meet the given closure specification.- Parameters:
spec- The specification to use. The closure gets a collection element as an argument.- Returns:
- The collection of matching objects. Returns an empty collection if there are no such objects in this collection.
