Method to load all elements from the "backing store" where appropriate.
|
V |
put(K key,
V value)
Method to add a value against a key to the LinkedHashMap.
|
void |

public Object clone()
Mutable second-class Objects are required to provide a public clone method in order to allow for copying persistable objects. In contrast to Object.clone(), this method must not throw a CloneNotSupportedException.
