Returns

MissionTaskGraphicBase

Properties

base

base: Feature<LineString | Point>;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:157

The center the graphic is built around, and — since it is now published from getFeatures() — the only part of a mission task that has to survive a save. Everything else regenerates from it plus size / rotation.

base is deliberately left false. That flag means "has vertices the Modify interaction may drag" (getRenderedFeaturesByProp('base')), which a point-anchored graphic does not: it is reshaped by rotate / resize / translate. Same trick as mobileDefense in controllerRegistry.ts. The role tag, not this flag, is what identifies the feature when serializing.

Implementation of

MissionTaskGraphic.base

---

center

center: Coordinate;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:145

The point the graphic is built around. Declared alongside size and rotation because the three together are the whole of a point-anchored graphic's editable state — which is exactly what save/restore has to carry.

Implementation of

MissionTaskGraphic.center

centerHandle

centerHandle: Feature<MultiPoint>;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:164

The center dot — visual anchor only.

handles

handles: Feature<MultiPoint>;

label

label: Feature;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:170

---

measure

measure: Feature;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:169

The radius read-out. Empty unless a gesture is in progress —

See

showMeasure.

---

mirrored

mirrored: boolean = false;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:476

Which side an asymmetric point-anchored graphic hangs its hook on — Pursuit's semicircle and P-line. Reflected in the graphic's own local frame, so it survives rotation. Stamped and replayed like any other geometry input.

name

name: TacticalGraphicName;

MissionTaskGraphic.name

rotation

rotation: number = 0;

Implementation of

MissionTaskGraphic.rotation

size

size: number;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:159

symbolId

symbolId: string = '';

Implementation of

MissionTaskGraphic.symbolId

Methods

centerCoordinate()

centerCoordinate(): Coordinate;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:763

The center, which is holder state rather than something to read back off the base.

It used to come from this.base.getGeometry().getCoordinates(), which is a coordinate for a point base and an array of them for an anchored one — so every style that consumed it silently got a nested array the moment a graphic converted.

Returns

Coordinate

Implementation of

MissionTaskGraphic.centerCoordinate

---

getFeatures()

getFeatures(): Feature<Geometry, {
[x: string]: any;
}>[];

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:610

Returns

Feature<Geometry, { [x: string]: any; }>[]

Implementation of

MissionTaskGraphic.getFeatures

---

setBaseFeature()

setBaseFeature(base): void;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:724

Adopts a new center point.

Used to be this.base = base and nothing else, which left center pointing at the old coordinate: the next rotate or resize — neither passes a center — would read the stale this.center back out and snap the graphic to where it used to be. Mission tasks are kept out of the Modify interaction so nothing reached this in practice, but it is on the public TacticalGraphicHandler interface and the manager calls it by symbolId.

Parameters

base

Feature<LineString | Point>

Returns

void

Implementation of

MissionTaskGraphic.setBaseFeature

setMirrored()

setMirrored(mirrored): void;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:479

Parameters

mirrored

boolean

Returns

void

See

TacticalGraphicHandler.setMirrored

Implementation of

MissionTaskGraphic.setMirrored

setSymbolId()

setSymbolId(symbolId): void;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:706

Parameters

symbolId

string

Returns

void

Implementation of

MissionTaskGraphic.setSymbolId

showMeasure()

showMeasure(active, anchor?): void;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:464

Arms or disarms the radius read-out.

Armed by the controller for the duration of a draw or resize gesture and disarmed when it ends, so the hashed line is a live measurement rather than decoration. Off by default, which is what keeps it out of a restored map and out of the sample gallery — both drive updateGeom without any gesture.

Parameters

active

boolean

anchor?

Coordinate

Returns

void

Implementation of

MissionTaskGraphic.showMeasure

---

updateGeom()

updateGeom(__namedParameters): void;

Defined in: components/openlayers/graphics/MissionTaskGraphicBase.ts:668
