# Class ActorsApi

OptimaJet.Workflow.Core.Runtime.ActorsApi

Provides APIs for resolving workflow participant identities and associated commands from workflow actor rules for a specific [WorkflowRuntime](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/WorkflowRuntime/) instance.

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

```csharp
public class ActorsApi
```

## Constructors

`public ActorsApi(WorkflowRuntime runtimeOwner)` 

Initializes a new instance of the [ActorsApi](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/ActorsApi/) class.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `runtimeOwner` | `WorkflowRuntime` | Workflow runtime that resolves workflow participant identities and command information. |

## Methods

`public Task<Dictionary<string, List<CommandWithClassifier>>> GetActorsWithCommandsAsync(ProcessInstance processInstance, List<TransitionClassifier> classifiers = null, CancellationToken token = default)` 

Gets workflow participant identities assigned to command transitions for the activity currently being executed, or the current activity when the process is idled, in the specified process and its subprocesses.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `processInstance` | `ProcessInstance` | Process instance that determines where the search starts. |
| `classifiers` | `List<TransitionClassifier>` | Optional transition classifiers used to filter command transitions. If [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null), all command transitions are included. |
| `token` | `CancellationToken` | A token to monitor for cancellation requests. |

### Returns

| Type | Description |
| --- | --- |
| `Task<String, CommandWithClassifier>` | A dictionary keyed by workflow participant identity, where each value contains the command names and transition classifiers associated with that identity by actor restrictions. |

### Remarks

Transition conditions are not evaluated.

`public Task<Dictionary<string, List<CommandWithClassifier>>> GetActorsWithCommandsAsync(TreeSearchFilter filter, List<TransitionClassifier> classifiers = null, CancellationToken token = default)` 

Gets workflow participant identities assigned to command transitions for processes selected by the provided search filter.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `filter` | `TreeSearchFilter` | Search configuration that defines the start point and traversal in the process instance tree. |
| `classifiers` | `List<TransitionClassifier>` | Optional transition classifiers used to filter command transitions. If [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null), all command transitions are included. |
| `token` | `CancellationToken` | A token to monitor for cancellation requests. |

### Returns

| Type | Description |
| --- | --- |
| `Task<String, CommandWithClassifier>` | A dictionary keyed by workflow participant identity, where each value contains the command names and transition classifiers associated with that identity by actor restrictions. |

### Remarks

Transition conditions are not evaluated.
