InstantiateFactory (Commons Collections 3.2.2 API)

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

All Implemented Interfaces:

Serializable, Factory
```
public class InstantiateFactory
extends Object
implements Factory, Serializable
```
Factory implementation that creates a new object instance by reflection.
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 InstantiateTransformer the following system property can be used (via -Dproperty=true):
```
 org.apache.commons.collections.enableUnsafeSerialization
 
```
Since:

Commons Collections 3.0
