- org.apache.commons.collections.functors.ForClosure

All Implemented Interfaces:

Serializable, Closure
```
public class ForClosure
extends Object
implements Closure, Serializable
```
Closure implementation that calls another closure n times, like a for loop.
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 ForClosure the following system property can be used (via -Dproperty=true):
```
 org.apache.commons.collections.enableUnsafeSerialization
 
```

Commons Collections 3.0
