Interface ICapabilityAccessor<TCapability>
A late-bound slot that may or may not currently hold a host capability of
type TCapability.
public interface ICapabilityAccessor<out TCapability> where TCapability : classType Parameters
TCapability
Remarks
Interactive-map capabilities (viewport control, coordinate conversion, snapshot rendering, presentation, and so on) are often unavailable at container-composition time — the map surface they wrap is created later, by the UI. Consumers therefore depend on ICapabilityAccessor<TCapability> rather than the capability directly, and read Current at the point of use, tolerating a null until the capability is wired up.
The type parameter is covariant so an accessor of a concrete capability satisfies an accessor of any interface it implements.
Properties
Current
The capability if it is currently available; otherwise null.
