# Class DecisionTable

OptimaJet.Workflow.Core.Plugins.BasicsPlugin.DecisionTable

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

```csharp
public class DecisionTable : ActivityBase
```

## Type Hierarchy

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

## Properties

`public override string Type { get; }` 

Gets or sets the form type identifier.

`public override string SVGTemplate { get; }` 

Gets or sets the name of the SVG element template used by the workflow designer to draw nodes of this activity type on the scheme canvas.

`public override string Title { get; }` 

Gets or sets the human-readable title for the form.

`public override string Template { get; }` 

Gets or sets the form template name used by UI renderers.

`public override string Description { get; }` 

Gets or sets the explanatory text displayed in the information tooltip for this activity in the workflow designer's element palette.

`public override bool AllowCycleTransition { get; }` 

Gets a value indicating whether the workflow designer allows a user to create a transition from a node of this activity type back to the same node.

### Remarks

This property controls the designer interaction; it is not a runtime validation rule for schemes created or modified through other APIs.

`public override bool IsOutgoingTransitionsReadonly { get; }` 

Gets a value indicating whether outgoing transitions are configured through this activity's editor instead of the standard transition editor.

### Remarks

Set this property when the custom activity form owns the configuration of its outgoing branches, as decision activity forms do.

`public override SaveToAnnotationsPolicy SaveToAnnotationsPolicy { get; }` 

Gets the policy that the workflow designer applies when saving values returned by this activity's editor to [ActivityDefinition.Annotations](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityDefinition/).

### Remarks

Regardless of this policy, the designer preserves the internal annotation used to associate an activity node with its custom type.

`public override Dictionary<string, object> DefaultValues { get; }` 

Gets or sets form-specific default values.

## 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. |
