 Producer<I> producer)

Method Details

assign

public final SequencedSet<? extends Assignment<?>> assign(Request<?> r)

Description copied from interface: Aggregate

Assigns a contextual reference to each of this Aggregate's AttributedElement instances and returns the resulting List of Assignments.

Specified by:

assign in interface Aggregate

Parameters:

r - a Request; must not be null

Returns:

a List of Assignment instances; never null

dependencies

public final SequencedSet<AttributedElement> dependencies()

Description copied from interface: Aggregate

Returns an unmodifiable SequencedSet of AttributedElement instances.

Specified by:

dependencies in interface Aggregate

Returns:

an unmodifiable SequencedSet of AttributedElement instances; never null

• AttributedElement

dispose

public final void dispose(I i,
 Request<I> r)

Specified by:

dispose in interface Producer<I>

produce

public final I produce(Request<?> r)

Specified by:

produce in interface Producer<I>

produce

public final I produce(SequencedSet<? extends Assignment<?>> assignments)

Description copied from interface: Producer

Produces a new contextual instance and returns it, possibly (often) making use of the supplied, dependent, contextual references.

Implementations of this method must not call Producer.produce(Request) or an infinite loop may result.

Specified by:

produce in interface Producer<I>

Parameters:

assignments - a SequencedSet of Assignments this Producer needs to create the contextual instance; must not be null

Returns:

a new contextual instance, or null
