Davesoft.LinkedPages 1.0.0.4

Handy for dividing a list of T while storing a T2 between each page.

Behold what the thing does:

    var book = new Davesoft.LinkedPages.Page<string, int>("A");
    Assert.Same(book.Item, "A");
    book.AddPageToEnd("BB");
    book.LastPage().PreviousJoiner.Item = 1;
    book.AddPageToEnd("CCC");
    book.LastPage().PreviousJoiner.Item = 3;
    var allpages = book.ListAllPages();
    Assert.Equal(3, allpages.Count);
    book.AddPageToEnd("DDDD");
    book.LastPage().PreviousJoiner.Item = 6;
    allpages = book.ListAllPages();
    Assert.Equal(4, allpages.Count);
    
    var sum = (from  j in book.ListAllJoiners() select j.Item).Sum();
    Assert.Equal(10, sum);
    Assert.Equal(allpages.Count-1, book.ListAllJoiners().Count);

    var victim1 = book.NextPage.NextPage; //make a ref to the page, or we'll lose it
    victim1.Replace("<", -1, ">");
    Assert.Equal(victim1.NextPage.PreviousPage.Item, victim1.PreviousPage.NextPage.PreviousPage.Item);
    Assert.Equal(victim1.NextPage.PreviousPage.FirstPage().Item, victim1.PreviousPage.NextPage.FirstPage().Item);
    Assert.Equal(book.Item, victim1.PreviousPage.NextPage.FirstPage().Item);
    Assert.Equal(book.Item, victim1.NextPage.PreviousPage.FirstPage().Item);


    Assert.NotEqual(victim1.Item, victim1.PreviousPage.NextPage.Item);
    Assert.NotEqual(victim1.NextPage.PreviousPage.Item, victim1.Item);

    WeakReference realTest = new WeakReference(victim1);
    victim1 = null;
    // ensure garbage collection
    // why choose when you can do em all
    System.GC.Collect();
    System.GC.WaitForFullGCApproach();
    System.GC.WaitForFullGCComplete();

    Assert.False(realTest.IsAlive); // important

    allpages = book.ListAllPages();

    sum = (from j in book.ListAllJoiners() select j.Item).Sum();
    Assert.Equal(9,sum);
    Assert.Equal(allpages.Count - 1, book.ListAllJoiners().Count);


    book.Replace("earst", 9, "2"); //replace the first page
    sum = (from j in book.ListAllJoiners() select j.Item).Sum();
    Assert.Equal(18, sum);
    Assert.True(book.HasBeenReplaced);
    Assert.Equal(book.PreviousPage,book.NextPage.FirstPage());
    Assert.Equal(book.FirstPage(), book.NextPage.FirstPage());

    realTest = new WeakReference(book);
    book = book.PreviousPage;
    // ensure garbage collection
    System.GC.Collect();
    System.GC.WaitForFullGCApproach();
    System.GC.WaitForFullGCComplete();

    Assert.False(realTest.IsAlive); // important

Also contains LinkedFaces, for linking faces of T together with binders of T2. Below is a simple D6 with named faces and worthless binder values.

        var atk = new Davesoft.LinkedFaces.BindFace<string, int>("atk");
        atk.AddBindFace("def", 0, "up", "down");
        atk.AddBindFace("eva", 0, "down", "up");
        var def = atk.Directions["up"].RouteMe(atk);
        Assert.Equal("def", def.Item);
        var acc= def.AddBindFace("acc", 0, "up", "down");
        var eva = atk.Directions["down"].RouteMe(atk);
        Assert.Equal("eva", eva.Item);

        acc.AddBinderToFace(eva, 0, "up", "down");

        var mgk = new Davesoft.LinkedFaces.BindFace<string, int>("mgk");

        var peace = new Davesoft.LinkedFaces.BindFace<string, int>("peace");

        var tmp = atk.Directions["up"].RouteMe(atk);
        var moves = 0;
        while (tmp.Item != atk.Item)
        {
            mgk.AddBinderToFace(tmp, 0, "mundaneward " + moves, "magicward");
            peace.AddBinderToFace(tmp, 0, "war " + moves, "peace");
            tmp = tmp.Directions["up"].RouteMe(tmp);
            moves++;
        }
        mgk.AddBinderToFace(tmp, 0, "mundaneward " + moves+1, "magicward");
        peace.AddBinderToFace(tmp, 0, "war " + moves+1, "peace");


        Assert.True(moves > 2);
        Assert.True(mgk.GetDirections().Count ==4);
        Assert.True(peace.GetDirections().Count == 4);
        Assert.True(atk.GetDirections().Count == 4);
        Assert.True(def.GetDirections().Count == 4);
        Assert.True(acc.GetDirections().Count == 4);
        Assert.True(eva.GetDirections().Count == 4);
