Method Detail

matching
TaskCollection<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.- Specified by:
matching
in interfaceDomainObjectCollection<T extends Task>
- Specified by:
matching
in interfaceNamedDomainObjectCollection<T extends Task>
- Specified by:
matching
in interfaceNamedDomainObjectSet<T extends Task>
- 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
TaskCollection<T> matching(Closure closure)
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.- Specified by:
matching
in interfaceDomainObjectCollection<T extends Task>
- Specified by:
matching
in interfaceNamedDomainObjectCollection<T extends Task>
- Specified by:
matching
in interfaceNamedDomainObjectSet<T extends Task>
- Parameters:
closure
- 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.
-
getByName
T getByName(String name, Closure configureClosure) throws UnknownTaskException
Locates an object by name, failing if there is no such object. The given configure closure is executed against the object before it is returned from this method. The object is passed to the closure as its delegate.- Specified by:
getByName
in interfaceNamedDomainObjectCollection<T extends Task>
- Parameters:
name
- The object nameconfigureClosure
- The closure to use to configure the object.- Returns:
- The object with the given name, after the configure closure has been applied to it. Never returns null.
- Throws:
UnknownTaskException
-
getByName
T getByName(String name) throws UnknownTaskException
Locates an object by name, failing if there is no such object.- Specified by:
getByName
in interfaceNamedDomainObjectCollection<T extends Task>
- Parameters:
name
- The object name- Returns:
- The object with the given name. Never returns null.
- Throws:
UnknownTaskException
-
withType
<S extends T> TaskCollection<S> withType(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.- Specified by:
withType
in interfaceDomainObjectCollection<T extends Task>
- Specified by:
withType
in interfaceNamedDomainObjectCollection<T extends Task>
- Specified by:
withType
in interfaceNamedDomainObjectSet<T extends Task>
- 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.
-
whenTaskAdded
Action<? super T> whenTaskAdded(Action<? super T> action)
Adds anAction
to be executed when a task is added to this collection.- Parameters:
action
- The action to be executed- Returns:
- the supplied action
-
whenTaskAdded
void whenTaskAdded(Closure closure)
Adds a closure to be called when a task is added to this collection. The task is passed to the closure as the parameter.- Parameters:
closure
- The closure to be called
-
getAt
T getAt(String name) throws UnknownTaskException
Locates an object by name, failing if there is no such task. This method is identical toNamedDomainObjectCollection.getByName(String)
. You can call this method in your build script by using the groovy[]
operator.- Specified by:
getAt
in interfaceNamedDomainObjectCollection<T extends Task>
- Parameters:

- The object name- Returns:
- The object with the given name. Never returns null.
- Throws:
