Class: NearestWaypointArray<T, EntryType>

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:66

An array of nearest waypoints backed by a nearest facilities subscription. Supports GPS data integrity state so that the array will be empty when no GPS position is available. Also supports pausing and resuming automatic updates from the backing nearest facilities subscription.

Type Parameters

Type Parameter	Default type
T extends NearestWaypointFacilityType	-
EntryType extends NearestWaypointEntry<NearestWaypointTypeMap[T]>	NearestWaypointEntry<NearestWaypointTypeMap[T]>

• SubscribableArray<EntryType>

Constructors

Constructor

new NearestWaypointArray<T, EntryType>(bus, waypointEntryFactory, isGpsDataFailed, gpsFailClearDelay): NearestWaypointArray<T, EntryType>

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:98

Constructor.

Parameters

Parameter	Type	Description
bus	EventBus	The event bus.
waypointEntryFactory	(waypoint) => EntryType	A function which creates nearest waypoint entries for this array.
isGpsDataFailed	Subscribable<boolean>	Whether GPS data is in a failed state.
gpsFailClearDelay	number	The delay, in milliseconds, after GPS data enters a failed state before this array is cleared of all waypoints.

Returns

NearestWaypointArray<T, EntryType>

Accessors

length

Get Signature

get length(): number

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:76

The length of this array.

Returns

number

The length of this array.

Implementation of

Methods

destroy()

destroy(): void

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:321

Destroys this array. Once this array is destroyed, it will be emptied and will no longer automatically update its contents and cannot be paused or resumed.

Returns

void

get()

get(index): EntryType

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:216

Retrieves an element from this array.

Parameters

Parameter	Type	Description
index	number	The index of the element.

Returns

EntryType

the element at the specified index.

Throws

Error if index is out of bounds.

Implementation of

SubscribableArray.get

---

getArray()

getArray(): readonly EntryType[]

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:226

Gets a read-only version of this array.

Returns

readonly EntryType[]

a read-only version of this array.

Implementation of

SubscribableArray.getArray

---

init()

init(nearestSubscription, paused): void

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:112

Initializes this array.

Parameters

Parameter	Type	Default value	Description
nearestSubscription	NearestSubscription<FacilityTypeMap[T]>	undefined	The nearest facility subscription that will provide this array's nearest waypoint data.
paused	boolean	false	Whether the array should be paused when initialized.

Returns

void

Throws

Error if this array has been destroyed.

---

pause()

pause(): void

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:200

Pauses this array. Once paused, this array's contents will no longer automatically update until it is resumed.

Returns

void

Throws

Error if this array has been destroyed.

---

resume()

resume(): void

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:182

Resumes this array. Once resumed, this array will automatically update its contents until it is paused or destroyed.

Returns

void

Throws

Error if this array has been destroyed.

---

sub()

sub(handler, initialNotify?, paused?): Subscription

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:231

Subscribes to changes in this array's state.

Parameters

Parameter	Type	Description
handler	SubscribableArrayHandler<EntryType>	A function which is called when this array's state changes.
initialNotify?	boolean	Whether to immediately invoke the callback function with this array's current state. Defaults to false. This argument is ignored if the subscription is initialized as paused.
paused?	boolean	Whether the new subscription should be initialized as paused. Defaults to false.

Returns

Subscription

The new subscription.

tryGet()

tryGet(index): EntryType | undefined

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:221

Attempts to retrieve an element from this array.

Parameters

Parameter	Type	Description
index	number	The index of the element.

Returns

EntryType | undefined

the element at the specified index, or undefined if index is out of bounds.

Implementation of

SubscribableArray.tryGet
