createInstance
@Nonnull @ReturnsMutableCopy public <K,V> CommonsHashMap<K,V> createInstance()
Description copied from interface:ICommonsMapCreate a new empty map. Overwrite this if you don't want to useCommonsHashMap.- Specified by:
createInstancein interfaceICommonsMap<KEYTYPE,VALUETYPE>- Type Parameters:
K- Map key typeV- Map value type- Returns:
- A new empty map. Never
null.

getClone
@Nonnull @ReturnsMutableCopy public CommonsHashMap<KEYTYPE,VALUETYPE> getClone()
- Specified by:
getClonein interfaceICloneable<KEYTYPE>- Returns:
- A 100% deep-copy of the implementing class.
