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.

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.

Methods
destroy()
destroy():
void
Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:303
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
getArray()
getArray(): readonly

Defined in: src/workingtitle-instruments-g3000/html_ui/Shared/Nearest/NearestWaypointArray.ts:225
Gets a read-only version of this array.
Returns
readonly EntryType
[]
a read-only version of this array.
Implementation of
init()
init(

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.
