- org.uncommons.watchmaker.swing.SelectionStrategyControl<T>

Type Parameters:

T - A generic type that matches the type associated with the selection strategies.

All Implemented Interfaces:

EvolutionControl
```
public class SelectionStrategyControl<T>
extends Object
implements EvolutionControl
```
An evolution control for selecting between different SelectionStrategy implementations. This control provides a proxy selection strategy that delegates to the currently selected strategy. Using this proxy strategy with an EvolutionEngine means that any change to the combo-box selection is immediately reflected in the selection used by the running evolution engine.
