Introduction

IEntry holds a value or an error, and state of entry.

// Create entry in unassigned state
IEntry<string> entry = new Entry<string>();
// Set processing
entry.SetProcessing();
// Set value
entry.SetValue("value");
// Set completed
entry.SetCompleted();
// Print status
WriteLine(entry.Status); // "Value, Completed"
// Dispose entry
((IDisposable)entry).Dispose();
// Print status
WriteLine(entry.Status); // "Disposed, Completed"

IEntry is used as the .Response property in IQuery.

// Get response
IEntry<string> response = (IEntry<string>)query.Response;
