IFilterStateLocator (Wicket Parent 9.18.0-SNAPSHOT API)

Type Parameters:

T - type of filter state object

All Superinterfaces:

IClusterable, Serializable
```
public interface IFilterStateLocator<T>
extends IClusterable
```
Locator that locates the object that represents the state of the filter. Usually it is convenient to let the data provider object implement this interface so that the data provider can be itself used to locate the filter state object. This also makes it easy for the data provider to locate the filter state which it will most likely need to filter the data.
Example
```
    class UserDataProvider extends SortableDataProvider implements IFilterStateLocator {
      private User filterBean=new User;
      
      public User getFilterState() { return filterBean; }
      public void setFilterState(User user) { filterBean=user; }
      
      public Iterator iterate(int start, int count) {
        getUserDao().find(start, count, filterBean);
      }
    }
 
```
