Cloneable
interface Cloneable
A class implements the Cloneable
interface to indicate to the java.lang.Object#clone()
method that it is legal for that method to make a field-for-field copy of instances of that class.
Invoking Object's clone method on an instance that does not implement the Cloneable
interface results in the exception CloneNotSupportedException
being thrown.
By convention, classes that implement this interface should override Object.clone
(which is protected) with a public method. See java.lang.Object#clone()
for details on overriding this method.
Note that this interface does not contain the clone
method. Therefore, it is not possible to clone an object merely by virtue of the fact that it implements this interface. Even if the clone method is invoked reflectively, there is no guarantee that it will succeed.
