Help with ILibraryManager

[pünktchen 1350]

I try to duplicate some of Emby's tv schedules methodes to my live tv plugins, but the implementation of "ILibraryManager" doesn't work.

I get a System.argument.Null.Exception. What i'm doing wrong?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Threading.Tasks;

using MediaBrowser.Controller.Entities;
using MediaBrowser.Controller.Entities.TV;
using MediaBrowser.Controller.Library;
using MediaBrowser.Controller.LiveTv;
using MediaBrowser.Model.Extensions;
using MediaBrowser.Model.Tasks;

namespace MediaBrowser.Plugins.MediaPortal.Helpers
{
    public class CheckTimers
    {
        //private readonly ILibraryManager _libraryManager;

        public void SkipTimers(CancellationToken cancellationToken)
        {
            MediaPortal1TvService tvservice = new MediaPortal1TvService();
            var timers = tvservice.GetTimersAsync(cancellationToken).Result;

            foreach ( var timer in timers)
            {
                if (IsAlreadyInLibrary(timer))
                {
                    tvservice.CancelTimerAsync(timer.Id, cancellationToken);
                }
            }
        }

        public bool IsAlreadyInLibrary(TimerInfo timer)
        {
            if ((timer.EpisodeNumber.HasValue && timer.SeasonNumber.HasValue) || !string.IsNullOrWhiteSpace(timer.EpisodeTitle))
            {
                var seriesIds = (this as ILibraryManager).GetItemIds(new InternalItemsQuery
                {
                    IncludeItemTypes = new[] { typeof(Series).Name },
                    Name = timer.Name

                }).Select(i => i.ToString("N")).ToArray();
                
                // It never reaches this point. System.Argument.Null.Exception
                
                if (seriesIds.Length == 0)
                {
                    return false;
                }

                //if (timer.EpisodeNumber.HasValue && timer.SeasonNumber.HasValue)
                //{
                //    var episode = _libraryManager.GetItemIds(new InternalItemsQuery
                //    {
                //        IncludeItemTypes = new[] { typeof(Episode).Name },
                //        ParentIndexNumber = timer.SeasonNumber.Value,

                //        IndexNumber = timer.EpisodeNumber.Value,
                //        AncestorIds = seriesIds,
                //        IsVirtualItem = false,
                //        Limit = 1
                //    });

                //    if (episode.Count > 0)
                //    {
                //        return true;
                //    }
                //}
            }
            return false;
        }
    }
}

Ok, your reference to _libraryManager is null. Try putting it into the constructor of your CheckTimers class.

[pünktchen 1350]

And that's my problem. How to do this without the need of implementing all methods of ILibraryManager?

public class CheckTimers : ILibraryManager

[Luke 40111]

You don't need to do that. Create a constructor for CheckTimers

public CheckTimers(ILibraryManager libraryManager){
_libraryManager = libraryManager;
}

[pünktchen 1350]

But if i do this

public class CheckTimers
{
    private readonly ILibraryManager _libraryManager;

    public CheckTimers(ILibraryManager libraryManager)
    {
        _libraryManager = libraryManager;
    }

    //Do something
}

what would be the parameter here

public Task CreateSeriesTimerAsync(SeriesTimerInfo info, CancellationToken cancellationToken)
{
    Plugin.TvProxy.CreateSeriesSchedule(cancellationToken, info);

    CheckTimers checkTimers = new CheckTimers(); //Missing ILibraryManager Parameter
    checkTimers.SkipTimers(cancellationToken);

    return Task.Delay(0, cancellationToken);
}

Same concept in that class. Add it to the constructor all the way up your call chain.

[pünktchen 1350]

Success! You're the man!

I really don't understand those constructors

Google "dependency injection c#" for some light reading .

Google "dependency injection c#" for some light reading .

I find being able to call the interfaces in the constructor sooo much easy to reuse class style structures.

 

Make coding with the API very easy

@@Luke is there a property to query for "Original Title" in ILibraryManager?

var seriesIds = _libraryManager.GetItemIds(new InternalItemsQuery
{
    IncludeItemTypes = new[] { typeof(Series).Name },
    // OriginalName = seriesName

}).Select(i => i.ToString("N")).ToArray();

[Luke 40111]

No, currently not.

Another one: How to get the name or id off all libraries?

[Luke 40111]

You mean the top level libraries?

[pünktchen 1350]

Yes.

[Luke 40111]

Do you want the collection folders from library setup? or the actual folder paths within them?

[pünktchen 1350]

Only the collections folder.

[Luke 40111]

Try this.

var folders = _libraryManager.GetUserRootFolder().Children.ToList();
