Class: IntersectionFacilityUtils

Defined in: src/sdk/navigation/Facilities.ts:1472

Utility functions for working with intersection facilities.

Constructors

new IntersectionFacilityUtils(): IntersectionFacilityUtils

Returns

IntersectionFacilityUtils

Methods

filterDuplicates()

Call Signature

static filterDuplicates(icaos, retainTerminal?): string[]

Defined in: src/sdk/navigation/Facilities.ts:1543

Filters an array of ICAOs such that the filtered array does not contain any duplicate terminal/non-terminal intersection pairs. All non-intersection ICAOs are guaranteed to be retained in the filtered array.

Parameters

Parameter	Type	Description
icaos	readonly string[]	The array to filter.
retainTerminal?	boolean	Whether to retain the terminal version of a duplicate pair in the filtered array. If true, each non-terminal intersection in the array will be filtered out if and only if the array contains at least one of its terminal intersection counterparts. If false, each terminal intersection in the array will be filtered out if and only if the array contains its non-terminal intersection counterpart. Defaults to false.

Returns

string[]

A copy of the original array with no duplicate terminal/non-terminal intersection pairs.

Call Signature

static filterDuplicates(facilities, retainTerminal?): Facility[]

Defined in: src/sdk/navigation/Facilities.ts:1554

Filters an array of facilities such that the filtered array does not contain any duplicate terminal/non-terminal intersection pairs. All non-intersection facilities are guaranteed to be retained in the filtered array.

Parameters

Parameter	Type	Description
facilities	readonly Facility[]	-
retainTerminal?	boolean	Whether to retain the terminal version of a duplicate pair in the filtered array. If true, each non-terminal intersection in the array will be filtered out if and only if the array contains at least one of its terminal intersection counterparts. If false, each terminal intersection in the array will be filtered out if and only if the array contains its non-terminal intersection counterpart. Defaults to false.

Returns

Facility[]

A copy of the original array with no duplicate terminal/non-terminal intersection pairs.

Call Signature

static filterDuplicates<T>(array, getIcao, retainTerminal?): T[]

Defined in: src/sdk/navigation/Facilities.ts:1568

Filters an array of arbitrary elements such that the filtered array does not contain any elements that are mapped to duplicate terminal/non-terminal intersection pairs. All elements that are not mapped to intersections are guaranteed to be retained in the filtered array.

Type Parameters

Type Parameter
T

Parameters

Parameter	Type	Description
array	readonly T[]	-
getIcao	(element) => string	A function which maps array elements to ICAOs.
retainTerminal?	boolean	Whether to retain the terminal version of a duplicate pair in the filtered array. If true, each non-terminal intersection in the array will be filtered out if and only if the array contains at least one of its terminal intersection counterparts. If false, each terminal intersection in the array will be filtered out if and only if the array contains its non-terminal intersection counterpart. Defaults to false.

Returns

T[]

A copy of the original array with no elements that are mapped to duplicate terminal/non-terminal intersection pairs.

getNonTerminalICAO()

static getNonTerminalICAO(icao): string

Defined in: src/sdk/navigation/Facilities.ts:1505

Gets the non-terminal version of an intersection ICAO. If the ICAO is already a non-terminal intersection ICAO, then an identical string will be returned.

Parameters

Parameter	Type	Description
icao	string	An intersection ICAO.

Returns

string

The non-terminal version of the specified intersection ICAO.

Throws

Error if the specified ICAO is not an intersection ICAO.

---

isTerminal()

Call Signature

static isTerminal(icao): boolean

Defined in: src/sdk/navigation/Facilities.ts:1480

Checks whether an intersection ICAO belongs to a terminal intersection.

Parameters

Parameter	Type
icao	string

Returns

boolean

Whether the specified intersection ICAO belongs to a terminal intersection.

Throws

Error if the specified ICAO is not an intersection ICAO.

Call Signature

static isTerminal(facility): boolean

Defined in: src/sdk/navigation/Facilities.ts:1486

Checks whether an intersection facility is a terminal intersection.

Parameters

Parameter	Type
facility	IntersectionFacility

Returns

boolean

Whether the specified intersection facility is a terminal intersection.

Throws

Error if the specified facility is not an intersection.
