| Name | Description | |
|---|---|---|
| constructor(params: QParams2d): QPoint2dList | Construct an empty list set up to use the supplied quantization parameters. | |
| add(pt: Point2d): void | Quantizes the supplied Point2d to this list's range and appends it to the list. | |
| clear(): void | Removes all points from the list. | |
| fromTypedArray(range: Range2d, array: Uint16Array): void | Create from a Uint16Array laid out such that array[0] corresponds to the first point's x component, array[1] to the first point's y component, and so on. |
|
| push(qpt: QPoint2d): void | Adds a previously-quantized point to this list. | |
| requantize(params: QParams2d): void | Changes the quantization parameters and requantizes all points in the list to the new range. | |
| reset(params: QParams2d): void | Removes all points from the list and change the quantization parameters. | |
| toTypedArray(): Uint16Array | Extracts the current contents of the list as a Uint16Array such that the first element of the array corresponds to the first point's x component, |
|
| unquantize(index: number, out?: Point2d): Point2d | Returns the unquantized value of the point at the specified index in the list. | |
| fromPoints(points: Point2d[], out?: QPoint2dList): QPoint2dList Static | Construct a QPoint2dList containing all points in the supplied list, quantized to the range of those points. |
