Methods

getNearest()

getNearest<T>(facilityType): undefined | FacilityTypeMap[T]

Defined in: src/workingtitle-instruments-g3x-touch/html_ui/Shared/Nearest/G3XNearestContext.ts:173

Gets the nearest facility for a given type.

Type Parameters

Type Parameter
T extends FacilityType

Parameters

Parameter	Type	Description
facilityType	T	The type of facility.

Returns

undefined | FacilityTypeMap[T]

---

update()

update(): Promise<void>

Defined in: src/workingtitle-instruments-g3x-touch/html_ui/Shared/Nearest/G3XNearestContext.ts:180

Updates this context.

Returns

Promise<void>

---

getInstance()

static getInstance(): Promise<G3XNearestContext>

Defined in: src/workingtitle-instruments-g3x-touch/html_ui/Shared/Nearest/G3XNearestContext.ts:194

Gets the G3XNearestContext instance on the local instrument.

Returns

Promise<G3XNearestContext>

A Promise which will be fulfilled with the G3XNearestContext instance on the local instrument once it is initialized.

---

initializeInstance()

static initializeInstance(facilityLoader, bus, fmsPosIndex): G3XNearestContext

Defined in: src/workingtitle-instruments-g3x-touch/html_ui/Shared/Nearest/G3XNearestContext.ts:206

Initializes and returns the G3XNearestContext instance on the local instrument. If the instance is already initialized, this method returns the instance without performing any other actions.

Parameters

Parameter	Type	Description
facilityLoader	FacilityLoader	A facility loader.
bus	EventBus	The event bus.
fmsPosIndex	number | Subscribable<number>	The index of the FMS geo-positioning system used by the context to get the airplane's position.

Returns

G3XNearestContext

The initialized G3XNearestContext instance on the local instrument.
