Namespace: [Grasshopper2.Doc.Attributes](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.doc.attributes.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```cs
public class OutputParameterAttributes : Attributes<IParameter>, IParameterAttributes
```

Attributes for standard output parameters.

## Constructors

- [OutputParameterAttributes](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/ctor.md): Constructor for output parameter attributes.

## Properties

- [HasInlet](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/hasinlet.md): Gets whether the inlet coordinate of these attributes represents a genuine inlet.
- [HasOutlet](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/hasoutlet.md): Gets whether the outlet coordinate of these attributes represents a genuine outlet.
- [Inlet](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/inlet.md): Gets the location for wire connections towards the sources of this parameter.
- [ModeBox](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/modebox.md): Gets the box within which the state icons will be drawn.
- [NameBox](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/namebox.md): Gets the box within which the name will be drawn.
- [Outlet](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/outlet.md): Gets the location for wire connections towards the recipients of this parameter.
- [Snappable](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/snappable.md)

## Methods

- [AssignBounds](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/assignbounds.md)
- [Draw](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/draw.md)
- [InvalidateLayout](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/invalidatelayout.md): Marks the layout as dirty so it gets recomputed on the next draw cycle. Subclasses typically flip an internal `_layoutValid` flag. Most callers should also raise [OnLayoutChanged](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.documentobject/onlayoutchanged.md) on the owner to actually trigger a canvas redraw.
- [Layout](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/layout.md): Perform a layout operation on these attributes. Layout() ought to be called as part of every control painting process.
- [PivotMoved](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/pivotmoved.md): Override this method if your attributes need to handle pivot motion. The default implementation translates [Bounds](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes-1/bounds.md) and [Stack](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes-1/stack.md) by the pivot delta. Overrides should typically chain to this base implementation.
- [ShowTooltipAt](https://developer.rhino3d.com/api/gh2/type/grasshopper2.doc.attributes.outputparameterattributes/showtooltipat.md)
