Method Details

createCollection

protected ImmutableList<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.

The returned collection class determines whether duplicate key-value pairs are allowed.

Specified by:

createCollection in class AbstractMultimap<K, V, ImmutableList<V>>

Returns:

an empty collection of values
