## Methods

`void Clear()` 

Clears all cached process definitions.

`bool RemoveProcessDefinition(Guid schemeId)` 

Removes a cached process definition by scheme identifier.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `schemeId` | `Guid` | The identifier of the scheme whose cached process definition should be removed. |

### Returns

| Type | Description |
| --- | --- |
| `Boolean` | [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) when a cached process definition was removed; otherwise, [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool). |

`ProcessDefinition GetProcessDefinitionBySchemeId(Guid schemeId)` 

Gets a cached process definition by scheme identifier.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `schemeId` | `Guid` | The identifier of the scheme for which to retrieve a process definition. |

### Returns

| Type | Description |
| --- | --- |
| `ProcessDefinition` | The cached process definition if one exists for `schemeId`; otherwise, [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |

`void AddProcessDefinition(Guid schemeId, ProcessDefinition processDefinition)` 

Adds or updates a process definition in the cache using the scheme identifier as key.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `schemeId` | `Guid` | The identifier of the scheme. |
| `processDefinition` | `ProcessDefinition` | The [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) to store in the cache. |
