IDeviceEventArgs<TDevice> Interface

Namespace: Yubico.Core.Devices Assembly: Yubico.Core.dll

Defines the contract for device-related event arguments in a generic context. This interface allows for type-safe access to device information in event handling scenarios, supporting device types that implement the IDevice interface. It enables specific device type information to be preserved and accessed in event handlers.

C#

public interface IDeviceEventArgs<out TDevice> where TDevice : IDevice

Type Parameters

Class.Header.Syntax.TypeParameters:Name	Description
TDevice	The specific type of IDevice this event argument represents. This type parameter is covariant, allowing for more specific device types to be used where a more general device type is expected.

Remarks

While this interface does not inherit from System.EventArgs, it retains the "Args" suffix in its name. This naming convention is deliberately chosen to maintain consistency with standard event argument naming patterns in C#, particularly for improved readability when used in delegate and event handler signatures. The familiar "Args" suffix clearly indicates the interface's role in event-related contexts, despite not directly extending System.EventArgs.

Properties

Name	Description
Device	Gets the specific type of IDevice that originated the event. This property will always be populated, regardless of whether this is an arrival event or a removal event. If the device was removed, not all members will be available on the object. An exception will be thrown if you try to use the device in a way that requires it to be present.
