Method Details

createInstance

@Nonnull
@ReturnsMutableCopy
public <K,
V> CommonsConcurrentHashMap<K,V> createInstance()

Description copied from interface: ICommonsMap

Create a new empty map. Overwrite this if you don't want to use CommonsHashMap.

Specified by:

createInstance in interface ICommonsMap<KEYTYPE,VALUETYPE>

Type Parameters:

K - Map key type

V - Map value type

Returns:

A new empty map. Never null.

getClone

@Nonnull
@ReturnsMutableCopy
public CommonsConcurrentHashMap<KEYTYPE,VALUETYPE> getClone()

Specified by:

getClone in interface ICloneable<KEYTYPE>

Returns:

A 100% deep-copy of the implementing class.
