IviServicePropertyDelegate

interface IviServicePropertyDelegate<T>
Content copied to clipboard

Interface to allow IVI service implementations to setup an IVI service property delegate.

Delegates are used for all interface properties. The purpose of this property delegate is to notify an observer of property changes and to keep the generated <Interface>Base classes free of initial values.

Custom setters are not possible in combination with delegates. Therefore, this interface is provided as an alternative.

Parameters

T

The property type. Is nullable for nullable properties.
