## Methods

`ProcessDefinition Parse(WorkflowRuntime workflowRuntime, TSchemeMedium schemeMedium, SchemeParsingType schemeParsingType = SchemeParsingType.Strict)` 

Parses an unparsed scheme representation into a [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `workflowRuntime` | `WorkflowRuntime` | The [WorkflowRuntime](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/WorkflowRuntime/) whose configuration is available during parsing. |
| `schemeMedium` | `{TSchemeMedium}` | The unparsed scheme representation. |
| `schemeParsingType` | `SchemeParsingType` | The parsing mode. Use [SchemeParsingType.Soft](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/SchemeParsingType/) only for an uploaded scheme that may contain an unresolved parameter CLR type. |

### Returns

| Type | Description |
| --- | --- |
| `ProcessDefinition` | The parsed [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/). |

`ProcessDefinition Parse(WorkflowRuntime workflowRuntime, string scheme, SchemeParsingType schemeParsingType = SchemeParsingType.Strict)` 

Parses scheme text into a [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `workflowRuntime` | `WorkflowRuntime` | The [WorkflowRuntime](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/WorkflowRuntime/) whose configuration is available during parsing. |
| `scheme` | `String` | The scheme text to parse. |
| `schemeParsingType` | `SchemeParsingType` | The parsing mode. Use [SchemeParsingType.Soft](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/SchemeParsingType/) only for an uploaded scheme that may contain an unresolved parameter CLR type. |

### Returns

| Type | Description |
| --- | --- |
| `ProcessDefinition` | The parsed [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/). |

`TSchemeMedium SerializeToSchemeMedium(ProcessDefinition processDefinition)` 

Serializes a [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) to the unparsed scheme representation.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `processDefinition` | `ProcessDefinition` | The [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) to serialize. |

### Returns

| Type | Description |
| --- | --- |
| `{TSchemeMedium}` | The serialized scheme represented by `TSchemeMedium`. |

`string SerializeToString(ProcessDefinition processDefinition)` 

Serializes a [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) to scheme text.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `processDefinition` | `ProcessDefinition` | The [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) to serialize. |

### Returns

| Type | Description |
| --- | --- |
| `String` | The serialized scheme text. |
