This is an extension and not part of the main GoJS library. Note that the API for this class may change at any time. If you intend to use an extension in production, you should copy the code to your own source directory. Extensions can be found in the GoJS kit under the `extensions` or `extensionsTS` folders. See the Extensions intro page for more information.

### Hierarchy

## Constructors

### constructor

- new OrthogonalLinkReshapingTool(): OrthogonalLinkReshapingTool

- Constructs an OrthogonalLinkReshapingTool and sets the name for the tool.

  #### Returns OrthogonalLinkReshapingTool

## Methods

### Override doDeactivate

- doDeactivate(): void

- This stops the current reshaping operation and updates any link handles.

  #### Returns void

### isApprox

- isApprox(x: number, y: number): boolean

- Compare two numbers to ensure they are almost equal. Used in this class for comparing coordinates of Points.

  #### Parameters

  - ##### x: number

  - ##### y: number

  #### Returns boolean

### makeSegmentDragHandle

- makeSegmentDragHandle(link: Link, adornment: Adornment, index: number): void

- Create the segment dragging handles. There are two parts: one invisible handle that spans the segment, and a visible handle at the middle of the segment. These are inserted at the front of the adornment such that the normal handles have priority.

  #### Parameters

  - ##### link: Link

  - ##### adornment: Adornment

  - ##### index: number

  #### Returns void

### Override reshape

- reshape(newpt: Point): void

- Change the route of the adornedLink by moving the segment corresponding to the current handle to be at the given Point.

  #### Parameters

  - ##### newpt: Point
