CloneTransformer (Commons Collections 3.2.2 API)

java.lang.Object
- org.apache.commons.collections.functors.CloneTransformer

All Implemented Interfaces:

Serializable, Transformer
```
public class CloneTransformer
extends Object
implements Transformer, Serializable
```
Transformer implementation that returns a clone of the input object.
Clone is performed using PrototypeFactory.getInstance(input).create().
WARNING: from v3.2.2 onwards this class will throw an UnsupportedOperationException when trying to serialize or de-serialize an instance to prevent potential remote code execution exploits.
In order to re-enable serialization support for CloneTransformer the following system property can be used (via -Dproperty=true):
```
 org.apache.commons.collections.enableUnsafeSerialization
 
```
Since:

Commons Collections 3.0
