How to make NavigationToolbar hide paging components at limits

First create a MyDefaultDataTable by copying org.apache.wicket.extensions.markup.html.repeater.data.table.DefaultDataTable.
This allows for us to pass our own MyNavigationToolbar. If there is a better way please let me know.

MyDefaultDataTable

 public class MyDefaultDataTable extends DataTable {
    
    public MyDefaultDataTable(String id, final List columns,
            ISortableDataProvider dataProvider, int rowsPerPage) {
        this(id, (IColumn[]) columns.toArray(new IColumn[columns.size()]),
                dataProvider, rowsPerPage);
    }

    public MyDefaultDataTable(String id, final IColumn[] columns,
            ISortableDataProvider dataProvider, int rowsPerPage) {
        super(id, columns, dataProvider, rowsPerPage);

        addTopToolbar(new MyNavigationToolbar(this));
        addTopToolbar(new HeadersToolbar(this, dataProvider));
        addBottomToolbar(new NoRecordsToolbar(this));
    }

    protected Item newRowItem(String id, int index, IModel model) {
        return new OddEvenItem(id, index, model);
    }

}

Next create MyNavigationToolbar and override the paging component creation methods.

MyNavigationToolbar

public class MyNavigationToolbar extends NavigationToolbar {
    public MyNavigationToolbar(DataTable table) {
        super(table);
    }
    @Override
    protected PagingNavigator newPagingNavigator(String navigatorId, DataTable table) {
        return new PagingNavigator(navigatorId, table) {
            @Override
            protected Link newPagingNavigationIncrementLink(String id, IPageable pageable, int increment) {
                return new PagingNavigationIncrementLink(id, pageable, increment) {
                    @Override
                    public boolean isVisible() {
                        return !linksTo(getPage());
                    }
                };
            }
            @Override
            protected Link newPagingNavigationLink(String id, IPageable pageable, int pageNumber) {
                return new PagingNavigationLink(id, pageable, pageNumber) {
                    @Override
                    public boolean isVisible() {
                        return !linksTo(getPage());
                    }
                };
            };
        };
    }
}
