Method Details

createInstance

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

Description copied from interface: ICommonsMap

Specified by:

createInstance in interface ICommonsMap<KEYTYPE,VALUETYPE>

Specified by:

createInstance in interface ICommonsOrderedMap<KEYTYPE,VALUETYPE>

Type Parameters:

K - Map key type

V - Map value type

Returns:

A new empty map. Never null.

getClone

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

Specified by:

getClone in interface ICloneable<KEYTYPE>

Specified by:

getClone in interface ICommonsOrderedMap<KEYTYPE,VALUETYPE>

Returns:

A 100% deep-copy of the implementing class.
