Class ConcurrentHashSetFactory

java.lang.Object

net.sf.mmm.util.collection.base.AbstractSetFactory

net.sf.mmm.util.collection.base.ConcurrentHashSetFactory

All Implemented Interfaces:

CollectionFactory<Set>, SetFactory

public class ConcurrentHashSetFactory
extends AbstractSetFactory

This is an implementation of ConcurrentMapFactory that creates instances of a ConcurrentHashSet. Since no such class exists in JDK, we provide it via ConcurrentHashMap.

Since:

5.0.0

Method Detail

create

public <E> Set<E> create()

Description copied from interface: CollectionFactory

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.

create

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

Description copied from interface: CollectionFactory

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.

getCollectionImplementation

public Class<? extends Set> getCollectionImplementation()

Description copied from interface: CollectionFactory

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

Returns:

the Collection implementation.
