| [get(number)](#get-number-)| Gets the gradient stop by the index. |
| [add(number, CellsColor, number)](#add-number-cellscolor-number-)| Add a gradient stop. |
| [add(number, Color, number)](#add-number-color-number-)| Add a gradient stop. |
| [getCount()](#getCount--)| <b>@deprecated.</b> Please use the 'count' property instead. Gets the number of elements contained in. |
| [isNull()](#isNull--)| Checks whether the implementation object is null. |

## \[Symbol.iterator\](): Iterator\<GradientStop\>

Returns an iterator over the items in the collection. Enables use of `for...of`, spread syntax, and `Array.from()`.



### get(number) {#get-number-}

The gradient stop.

### add(number, CellsColor, number) {#add-number-cellscolor-number-}

Add a gradient stop.

```javascript
add(position: number, color: CellsColor, alpha: number) : void;
```

**Parameters:**
