# IInputBasePortBuilder<T>

> Base interface for input port builders in a port definition context.

## Definition

* **Type:** Interface
* **Namespace:** [Unity.GraphToolkit.Editor](/engine/6000.6/script-reference/unity/graphtoolkit/editor.md)
* **Assembly:** UnityEditor

```csharp
public interface IInputBasePortBuilder<T> : IPortBuilder<T>
```

## Remarks

Use this interface when defining input ports in a custom node. It extends the generic [IPortBuilder\<T>](/engine/6000.6/script-reference/unity/graphtoolkit/editor/iportbuilder1.md) interface with input-specific configuration options. The generic parameter `T` allows method chaining using the builder pattern.
