# IPortBuilder<T>

> Base interface representing a generic port builder. Used in a builder pattern to configure and construct ports.

## Definition

* **Type:** Interface
* **Namespace:** [Unity.GraphToolkit.Editor](/engine/6000.7/script-reference/unity/graphtoolkit/editor.md)
* **Assembly:** UnityEditor

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

## Remarks

This interface supports a builder pattern, where each method returns the builder instance, allowing chained configuration of port settings before final construction using [IPortBuilder\<T>.Build()](/engine/6000.7/script-reference/unity/graphtoolkit/editor/iportbuilder1/build.md). Use derived interfaces such as [IInputPortBuilder](/engine/6000.7/script-reference/unity/graphtoolkit/editor/iinputportbuilder.md) or [IOutputPortBuilder](/engine/6000.7/script-reference/unity/graphtoolkit/editor/ioutputportbuilder.md) to build specific port types.

## Examples

```csharp
context.AddInputPort("MyInput")
       .WithDataType(typeof(int))
       .WithDisplayName("Input Value")
       .Build();
```

| [WithCapacity](/engine/6000.7/script-reference/unity/graphtoolkit/editor/iportbuilder1/withcapacity.md)       | Configures the connection capacity of the port being built.                                                                                                          |
