HashBagMultimapWithHashingStrategy

@Deprecated
public HashBagMultimapWithHashingStrategy()

Deprecated.

Empty default constructor used for serialization. Instantiating an HashBagMultimapWithHashingStrategy with this constructor will have a null multimapHashingStrategy, and throw NullPointerException when used.
