Annotation Type Nullable

@Retention(value=RUNTIME)
public @interface Nullable

This annotation is used to tag methods and parameters to give extra information on how they handle null. SweetBlue strives to never return null if it doesn't have to, preferring things like BleDeviceState.NULL for example, but in some situations it's unavoidable.

NOTE: This annotation is only used in places where the library authors have judged that the API by itself may be unclear about its null handling for newcomers. In general, if this annotation isn't used, you may assume Nullable.Prevalence.NEVER.
