Remarks

This class is a specialized version of the ErrorTask class and represents an item that reports a problem in the parsing of the current source file. In addition, it supports the functionality of jumping to the line that caused the error. This class overrides the ErrorTask and Task base classes and creates an IVsTextLineMarker object that manages a span in a buffer and provides custom navigation to the source of the error.

Notes to Inheritors

This class contains all the functionality that is required to manage an item in the Error List Options window. You can derive from this class to change marker command behaviors. Beyond this, you do not have to derive from this class.

Notes to Callers

An instance of this class is created in the Microsoft.VisualStudio.Package.Source.CreateErrorTaskItem(Microsoft.VisualStudio.TextManager.Interop.IVsTextLineMarker,Microsoft.VisualStudio.TextManager.Interop.TextSpan,System.String) method in the Source class. The Source class uses the DocumentTask class to show all warnings and errors that are produced by the language service parser. Typically, the Source class handles all instances of the DocumentTask class internally.

Constructors

DocumentTask(IServiceProvider, IVsTextLines, MARKERTYPE, TextSpan, String)
