## Properties

`public static IDesignerParameterFormatProvider Value { get; }` 

Gets the shared empty Designer parameter format provider.

## Methods

`public List<CodeActionParameterDefinition> GetFormat(CodeActionType type, string name, string schemeCode)` 

Gets the ordered form-field definitions for a named action, condition, or rule.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `type` | `CodeActionType` | The parameter usage context: [CodeActionType.Action](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionType/), [CodeActionType.Condition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionType/), [CodeActionType.RuleCheck](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionType/), or [CodeActionType.RuleGet](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionType/). |
| `name` | `String` | The action, condition, or rule name selected in the Designer. |
| `schemeCode` | `String` | The current process scheme code, which can be used to provide scheme-specific fields. The value may be [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) when the format is requested without a process scheme context. |

### Returns

| Type | Description |
| --- | --- |
| `List<CodeActionParameterDefinition>` | An ordered list containing one [CodeActionParameterDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/CodeActionParameterDefinition/) per form field. Returning [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) or an empty list indicates that no structured parameter editor is defined; the Designer then uses its raw JSON editor. |

### Remarks

All arguments are ignored.

## Remarks

The provider ignores the requested code action type, name, and scheme and always returns an empty list.
