# ConditionReference

> Identifies a condition inside a visualization ConditionReference.Context so visualization changes can be applied to it.

## Definition

* **Type:** Struct
* **Namespace:** [Unity.GraphToolkit.Editor.GraphVisualization](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization.md)
* **Assembly:** UnityEditor
* **Implements:** [IEquatable\<ConditionReference>](https://learn.microsoft.com/dotnet/api/system.iequatable-1)

```csharp
public readonly struct ConditionReference : IEquatable<ConditionReference>
```

## Remarks

Obtain a [ConditionReference](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/conditionreference.md) from [Context.GetConditionReference](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/context/getconditionreference.md), providing the unique identifier of the condition. The reference is only meaningful for the [ConditionReference.Context](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/conditionreference/context.md) that produced it. Two [ConditionReference](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/conditionreference.md) values are equal when they share the same [ConditionReference.ConditionID](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/conditionreference/conditionid.md) and refer to the same [ConditionReference.Context](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/conditionreference/context.md) instance.

Create a visualization context for a graph, retrieve a [ConditionReference](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graphvisualization/conditionreference.md) for a condition, apply a customization, then clear it.

## Examples

```csharp
using Context context = Registry.CreateVisualizationContext(graph.ID);
ConditionReference condition = context.GetConditionReference(conditionID);
condition.Icon = DebugStyles.PendingIcon;
condition.ClearCustomization();
```
