Method Detail

getCollectionImplementation

public Class<HashSet> getCollectionImplementation()

This method gets the implementation of the collection-interface used by this factory.

Returns:

the Collection implementation.

create

public <E> Set<E> create()

This method creates a new Collection instance.
It is explicitly typed and respects the generic element type of the collection. Therefore the type of the Collection can NOT be bound to the generic type <COLLECTION> because of limitations in Java's generic type system. You need to work on the actual sub-interface (e.g. ListFactory) to get the proper result type.

Type Parameters:

E - the type of elements contained in the collection.

Returns:

the new collection instance.

CollectionFactory.createGeneric()

create

public <E> Set<E> create(int capacity)

This method creates a new Collection instance with the given initial capacity.
It is explicitly typed and respects the generic element type of the collection. Therefore the type of the Collection can NOT be bound to the generic type <COLLECTION> because of limitations in Java's generic type system. You need to work on the actual sub-interface (e.g. ListFactory) to get the proper result type.

Type Parameters:

E - the type of elements contained in the collection.

Parameters:

capacity - is the initial capacity of the collection.

Returns:

the new collection instance.
