Constructors

constructor

new MultiTouchDataImpl(): MultiTouchDataImpl
Creates the interaction data

Returns MultiTouchDataImpl
Overrides MultiTouchDataBase.constructor
- Defined in impl/interaction/MultiTouchDataImpl.ts:43

Properties

`Protected` `Readonly` touchesData

touchesData: Map<number, SrcTgtTouchDataImpl>

Accessors

touches

get touches(): readonly SrcTgtPointsData<TouchData>[]
The list of touch data.

Returns readonly SrcTgtPointsData<TouchData>[]
Overrides MultiTouchDataBase.touches
- Defined in impl/interaction/MultiTouchDataImpl.ts:48

Methods

addTouchData

addTouchData(data): void
Adds a touch data to this multi-touch data
Parameters
- data: SrcTgtTouchDataImpl
  The touch data to add
Returns void
- Defined in impl/interaction/MultiTouchDataImpl.ts:56

flush

flush(): void
Flushes data.

Returns void
Implementation of Flushable.flush
- Defined in impl/interaction/MultiTouchDataImpl.ts:68

isHorizontal

isHorizontal(pxTolerance): boolean
Parameters
- pxTolerance: number
  The pixel tolerance for considering the line horizontal.
Returns boolean
True if the line of each touch is relatively horizontal and in the same direction.
- Defined in impl/interaction/MultiTouchDataImpl.ts:93

isVertical

isVertical(pxTolerance): boolean
Parameters
- pxTolerance: number
  The pixel tolerance for considering the lines vertical.
Returns boolean
True if the line of each touch is relatively vertical and in the same direction.
- Defined in impl/interaction/MultiTouchDataImpl.ts:113

removeTouchData

removeTouchData(id): void
Parameters
- id: number
Returns void
- Defined in impl/interaction/MultiTouchDataImpl.ts:60

setTouch

setTouch(tp, evt): void
Sets new value for the given touch point. The identifier of the given event point is used to find the corresponding touch data.
Parameters
- tp: Touch
  The touch event data to use.
- evt: TouchEvent
  The touch event
Returns void
- Defined in impl/interaction/MultiTouchDataImpl.ts:82

velocity

velocity(direction): number
The velocity of the move, in pixels per millisecond. For multi-touch, the velocity is the mean of all the touch velocities.
Parameters
- direction: "all" | "horiz" | "vert"
  The direciton to consider.
Returns number
Inherited from MultiTouchDataBase.velocity
- Defined in impl/interaction/MultiTouchDataImpl.ts:28
