# FunctionUi<T> class

Namespace: [Grasshopper2.UI.Graphing](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.ui.graphing.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```cs
public abstract class FunctionUi<T> : FunctionUi
```

Abstract class for function interfaces.

**Type parameters:**

- `T` (where Function): Type of Function to wrap.

## Constructors

- [FunctionUi<T>](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/ctor.md): (2 overloads)

## Properties

- [Func](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/func.md): Gets the function representing the current state.
- [Function](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/function.md)

## Methods

- [CanInsertVector](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/caninsertvector.md): Test whether a grip can be inserted at or near a coordinate.
- [CanRemoveVector](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/canremovevector.md): Override this method to specifically okay removal off a specific grip.
- [CreateFromArguments](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/createfromarguments.md): This method is called by the base class whenever the equation needs to be updated to reflect the current grip state.
- [OverrideFunctionCache](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/overridefunctioncache.md): Override the cached function. You typically never need this. It's here for those rare cases where grips or scalars are modified in such a way so as to not affect the underlying function.
- [TryInsertVector](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/tryinsertvector.md): Try and insert a grip at a coordinate.
- [TryRemoveVectors](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.graphing.functionui-1/tryremovevectors.md): Try and remove a set of grips.
