All Implemented Interfaces:

ParameterNameDiscoverer
```
public class PrioritizedParameterNameDiscoverer
extends Object
implements ParameterNameDiscoverer
```
ParameterNameDiscoverer implementation that tries several ParameterNameDiscoverers in succession. Those added first in the addDiscoverer method have highest priority. If one returns null, the next will be tried.
