```csharp
public sealed class GeneratedCustomActivity : ActivityBase
```

## Type Hierarchy

-   [FormBase](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/FormBase/)
    -   [ActivityBase](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/ActivityBase/)
        -   GeneratedCustomActivity Current type

## Constructors

`public GeneratedCustomActivity(string type, string title, string description, CustomActivityAsyncAction asyncAction, ParametersGetter parametersGetter, DisabledGetter disabledGetter)` 

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `type` | `String` |  |
| `title` | `String` |  |
| `description` | `String` |  |
| `asyncAction` | `CustomActivityAsyncAction` |  |
| `parametersGetter` | `ParametersGetter` |  |
| `disabledGetter` | `DisabledGetter` |  |

`public GeneratedCustomActivity(string type, string title, string description, CustomActivitySyncAction asyncAction, ParametersGetter parametersGetter, DisabledGetter disabledGetter)` 

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `type` | `String` |  |
| `title` | `String` |  |
| `description` | `String` |  |
| `asyncAction` | `CustomActivitySyncAction` |  |
| `parametersGetter` | `ParametersGetter` |  |
| `disabledGetter` | `DisabledGetter` |  |

## Properties

`public override bool Disabled { get; set; }` 

Gets a value, calculated by the callback supplied to the constructor, indicating whether this activity type is hidden from the workflow designer.

### Exceptions

| Type | Description |
| --- | --- |
| `NotImplementedException` | The property setter is not implemented. |

### Remarks

Hiding an activity affects designer discovery only: it remains registered with the runtime, so existing scheme nodes can still execute it. The set accessor is not implemented by this base class.

`public override List<CodeActionParameterDefinition> Parameters { get; set; }` 

Gets or sets the form parameter definitions.

`public override BaseTemplate BaseTemplate { get; }` 

Gets the data model that the workflow designer uses with [FormBase.Template](https://api.workflowengine.io/core/OptimaJet.Workflow.Core/FormBase/) when editing this activity.

## Methods

`public override Task ExecutionAsync(WorkflowRuntime runtime, ProcessInstance processInstance, Dictionary<string, string> parameters, CancellationToken token)` 

Executes the form operation during normal workflow execution.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `runtime` | `WorkflowRuntime` | The [WorkflowRuntime](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/WorkflowRuntime/) invoking the execution. |
| `processInstance` | `ProcessInstance` | The current [ProcessInstance](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/). |
| `parameters` | `Dictionary<String, String>` | Runtime parameter values for the executed form operation, keyed by parameter name. |
| `token` | `CancellationToken` | The [CancellationToken](https://learn.microsoft.com/dotnet/api/system.threading.cancellationtoken) passed from the execution pipeline. |

### Returns

| Type | Description |
| --- | --- |
| `Task` | A [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) that represents the asynchronous execution. |

`public override Task PreExecutionAsync(WorkflowRuntime runtime, ProcessInstance processInstance, Dictionary<string, string> parameters, CancellationToken token)` 

Executes the form operation during pre-execution simulation.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `runtime` | `WorkflowRuntime` | The [WorkflowRuntime](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/WorkflowRuntime/) invoking the simulation. |
| `processInstance` | `ProcessInstance` | The current [ProcessInstance](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/). |
| `parameters` | `Dictionary<String, String>` | Runtime parameter values for the simulated operation, keyed by parameter name. |
| `token` | `CancellationToken` | The [CancellationToken](https://learn.microsoft.com/dotnet/api/system.threading.cancellationtoken) passed from the execution pipeline. |

### Returns

| Type | Description |
| --- | --- |
| `Task` | A [Task](https://learn.microsoft.com/dotnet/api/system.threading.tasks.task) that represents the asynchronous simulation. |
