Constructor: LongRunningTask(action, executingNode)

LongRunningTask

task runs time-bound or CPU-bound code.

LongRunningTask(Action action, IUANode executingNode);

Arguments

action (Action): The method or lambda expression to run.
executingNode (IUANode): The node in which the code runs.

Example

myLongRunningTask

task processes a CSV file using the

ProcessCsvFile()

method. This method takes the task itself as argument, the status of which is checked using the

IsCancellationRequested

property after reading each row of the CSV file. In this way, the task can be canceled.

using namespace System.IO; // For using the StreamReader
class public override void Start()
{
    myLongRunningTask = new LongRunningTask(ProcessCSVFile, LogicObject);
    myLongRunningTask.Start();
}

public override void Stop()
{
    myLongRunningTask.Dispose();
}

private void ProcessCsvFile(LongRunningTask task)
{
    using (var reader = new StreamReader(pathToCsvFile))
    {
        while (!reader.EndOfStream)
        {
            // Check whether task cancellation has been requested
            if (task.IsCancellationRequested)
            {
                // Properly handle task cancellation here
                return;
            }

            string line = reader.ReadLine();
            // Process line
        }
    }
}

private LongRunningTask myLongRunningTask;
