FilterSelector
```
public interface Selectee<T>
```
Represents an operation that is used exclusively as a helper to some Selector's Selector.mapSelected(swim.structure.Interpreter, swim.structure.Selectee<swim.structure.Item>) or Selector.forSelected(swim.structure.Interpreter, swim.structure.Selectee<T>) methods.

- Method Summary

  T selected(Interpreter interpreter)
  Performs this operation against interpreter.

- Method Detail
  - selected
```
T selected(Interpreter interpreter)
```
    Performs this operation against interpreter. By convention, a null return value indicates to "collection-oriented" calling Selectors (e.g. ChildrenSelector, KeysSelector) that forSelected should continue to be invoked, if possible. A non-null value indicates to such Selectors that forSelected should return immediately.
