What is Time Shifter ?

Time Shifter with a one sentences "Do not make a database call, wait ! Oh still user is typing some text. Time to go ? No still typing wait more. Hmm seems good now, lets search make a database request and search on db (or api etc.) !" Time Shifter is a solution to postpone serverside requests/calls for a specific time and making it only on idle time. It is useful for SearchBoxes to make a db call when user is idle. Whenever user continue typing etc. db call or api request pospones for a specific time.

Problem

• Calling DB/Api on every event or on action and can't cancelling previous one
• Recursive database requests or api requests
• Unexpectable user behaviour

Benefits

Useful for search text areas. Prevents several DB or Api calls in every key press or x action.

Purpose of Time Shifter ?

Solves running calls depending on unexpected situations. If you don't know when to make a DB call depending on user key typings TimeShifter will solve that issue. It is not a good way to call db or api on every user typing or call it every x seconds. The better way is "When user stops typing" so timeshifter calls only 1 time when user is idle.

Code Sample

public partial class Form1 : Form
{
    TimeShifter<string> shifter;

    public Form1()
    {
        InitializeComponent();
        shifter = new TimeShifter<string>(3000, 200);

        //test purpose
        lblTime.Text = $"{shifter.ShiftingTime.ToString()} milliseconds";
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        shifter.OnEndShiftingTime += Shifter_OnEndShiftingTime;
    }

    private void Shifter_OnEndShiftingTime(string obj)
    {
        listBox1.Items.Add($"Time to go db !");
        listBox1.Items.Add($"Search: {obj}");
    }

    private async void txtSearch_TextChanged(object sender, EventArgs e)
    {
        listBox1.Items.Add($"No need to DB Call on text change..");
        await shifter.Shift(txtSearch.Text);
    }
}
