Modifier and Type	Method and Description
public T	Returns: an instance of the bean, or `null` if not available getIfAvailable() Return an instance (possibly shared or independent) of the object managed by this factory.
public default T	Returns: an instance of the bean, or the supplied default object if no such bean is available getIfAvailable(Supplier<T> a callback for supplying a default object if none is present in the factory defaultSupplier) Return an instance (possibly shared or independent) of the object managed by this factory.
public T	Returns: an instance of the bean, or `null` if not available or not unique (i.e. multiple candidates found with none marked as primary) getIfUnique() Return an instance (possibly shared or independent) of the object managed by this factory.
public default T	Returns: an instance of the bean, or the supplied default object if no such bean is available or if it is not unique in the factory (i.e. multiple candidates found with none marked as primary) getIfUnique(Supplier<T> a callback for supplying a default object if no unique candidate is present in the factory defaultSupplier) Return an instance (possibly shared or independent) of the object managed by this factory.
public T	Returns: an instance of the bean getObject(Object... arguments to use when creating a corresponding instance args) Return an instance (possibly shared or independent) of the object managed by this factory.
public default void	ifAvailable(Consumer<T> a callback for processing the target object if available (not called otherwise) dependencyConsumer) Consume an instance (possibly shared or independent) of the object managed by this factory, if available.

public default Iterator<T>	iterator() Implements java.lang.Iterable.iterator. Return an `Iterator` over all matching object instances, without specific ordering guarantees (but typically in registration order).
