## Methods

`ITransitionParallelStartBuilder SameThread()` 

Sets [TransitionDefinition.SubprocessStartupType](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/) to [SubprocessStartupType.SameThread](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SubprocessStartupType/), executing the subprocess inline in the parent process's execution flow.

### Returns

### Returns

| Type | Description |
| --- | --- |
| `ITransitionParallelStartBuilder` | The current instance of [ITransitionParallelStartBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionParallelStartBuilder/). |

`ITransitionParallelStartBuilder SubprocessName(string name)` 

Sets [TransitionDefinition.SubprocessName](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/) for the subprocess started by the transition.

### Parameters

`ITransitionParallelStartBuilder AutoSubprocessName()` 

Clears [TransitionDefinition.SubprocessName](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/), causing the transition name to be used as the subprocess name.

### Returns

| Type | Description |
| --- | --- |

`ITransitionParallelStartBuilder AutoSubprocessId()` 

Clears [TransitionDefinition.SubprocessId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/), causing [Guid.NewGuid()](https://learn.microsoft.com/dotnet/api/system.guid.newguid) to generate the subprocess's process ID when the subprocess starts.

### Returns

| Type | Description |
| --- | --- |
| `ITransitionParallelStartBuilder` | The current instance of [ITransitionParallelStartBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionParallelStartBuilder/). |

`ITransitionParallelStartBuilder CopyAllParameters()` 

Sets [TransitionDefinition.SubprocessStartupParameterCopyStrategy](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/) to [SubprocessStartupParameterCopyStrategy.CopyAll](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/SubprocessStartupParameterCopyStrategy/) and clears [TransitionDefinition.SubprocessSpecifiedParameters](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/), copying every parent-process parameter whose purpose is not [ParameterPurpose.System](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterPurpose/) to the subprocess.

### Returns

| Type | Description |
| --- | --- |
| `ITransitionParallelStartBuilder` | The current instance of [ITransitionParallelStartBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionParallelStartBuilder/). |

`ITransitionParallelStartBuilder CopyParameters(List<string> parameters)`

Only parent-process parameters whose purpose is not [ParameterPurpose.System](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterPurpose/) and whose names are specified are copied to the subprocess.

### Parameters

Every parent-process parameter whose purpose is not [ParameterPurpose.System](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ParameterPurpose/) is copied except those whose names are specified.

### Parameters

| Name | Type | Description |

### Returns

| Type | Description |

`ITransitionParallelStartBuilder DisableParentProcessControl()` 

Sets [TransitionDefinition.DisableParentStateControl](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/) to [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), so parent-process activity changes do not automatically remove the subprocess.

### Returns

| Type | Description |
| --- | --- |
| `ITransitionParallelStartBuilder` | The current instance of [ITransitionParallelStartBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionParallelStartBuilder/). |

`ITransitionParallelStartBuilder EnableParentProcessControl()` 

Sets [TransitionDefinition.DisableParentStateControl](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/) to [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), allowing the subprocess to be removed automatically when the parent process leaves the activities in which it may exist.

### Returns

| Type | Description |
| --- | --- |
| `ITransitionParallelStartBuilder` | The current instance of [ITransitionParallelStartBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionParallelStartBuilder/). |
