createCollection

protected UnifiedSetWithHashingStrategy<V> createCollection()

Description copied from class: AbstractMultimap

Creates the collection of values for a single key.

Collections with weak, soft, or phantom references are not supported. Each call to createCollection should create a new instance.

Returns:

an empty collection of values
