# Class CodeActionsInvoker

OptimaJet.Workflow.Core.CodeActions.CodeActionsInvoker

Stores compiled actions, conditions, and rules and invokes them by their logical names.

Namespace: [OptimaJet.Workflow.Core.CodeActions](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/)

```csharp
public sealed class CodeActionsInvoker
```

## Methods

`public void AddCompilledType(Type compilledType)` 

Discovers generated public static code-action methods on `compilledType` and registers delegates for invoking them.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `compilledType` | `Type` | The compiled type that contains code action methods. |

### Exceptions

| Type | Description |
| --- | --- |
| `ArgumentException` | Thrown when a public static method does not end with a recognized [CodeActionType](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionType/), or when the same generated method name is registered more than once. |

### Remarks

The final underscore-delimited segment of each method name, before an optional `Async` suffix, must identify its [CodeActionType](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionType/). Invocation methods reconstruct the registered method name with [CodeActionUtils.GetMethodName(string, CodeActionType)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/CodeActionUtils/) or [CodeActionUtils.GetAsyncMethodName(string, CodeActionType)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/CodeActionUtils/).
