# Class SerializedParameter

OptimaJet.Workflow.Core.Model.SerializedParameter

Represents a process parameter prepared for persistence, including its [SerializedParameter.Name](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/), [SerializedParameter.SerializedValue](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/), and required [SerializedParameter.Operation](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/).

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

```csharp
public sealed class SerializedParameter
```

## Properties

`public string Name { get; }` 

Gets the name of the process parameter represented by this instance.

`public string? SerializedValue { get; }` 

Gets the serialized process parameter value to persist.

`public SerializedParameter.PersistenceOperation Operation { get; }` 

Gets the [SerializedParameter.PersistenceOperation](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter.PersistenceOperation/) to apply to the process parameter.

## Methods

`public static SerializedParameter Create(ParameterDefinitionWithValue parameter)` 

Prepares `parameter` for persistence by producing its [SerializedParameter.SerializedValue](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/) and selecting its [SerializedParameter.Operation](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `parameter` | `ParameterDefinitionWithValue` | The [ParameterDefinitionWithValue](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterDefinitionWithValue/) that represents the process parameter to prepare. |

### Returns

| Type | Description |
| --- | --- |
| `SerializedParameter` | A [SerializedParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/) whose [SerializedParameter.Name](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/), [SerializedParameter.SerializedValue](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/), and [SerializedParameter.Operation](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter/) describe the required persistence change. |

### Exceptions

| Type | Description |
| --- | --- |
| `ArgumentNullException` | `parameter` is [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |
| `InvalidCastException` | [ParameterDefinitionWithValue.IsImplicit](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterDefinitionWithValue/) is [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) and [ParameterDefinitionWithValue.Value](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterDefinitionWithValue/) is not a [string](https://learn.microsoft.com/dotnet/api/system.string) or [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |

### Remarks

When [ParameterDefinitionWithValue.IsImplicit](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterDefinitionWithValue/) is [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), the value of [ParameterDefinitionWithValue.Value](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterDefinitionWithValue/) is used as a [string](https://learn.microsoft.com/dotnet/api/system.string) without serialization. Otherwise, the value is serialized by [ParametersSerializer.Serialize(object, Type)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/ParametersSerializer/). A [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) serialized value selects [SerializedParameter.PersistenceOperation.Delete](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter.PersistenceOperation/). For any other value, the method selects [SerializedParameter.PersistenceOperation.Insert](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter.PersistenceOperation/) when the source parameter is not marked as existing in the persistence store and [SerializedParameter.PersistenceOperation.Update](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SerializedParameter.PersistenceOperation/) when it is.

## Nested Types

`public enum SerializedParameter.PersistenceOperation` 

Specifies the operation required to persist a process parameter value.
