```

## Type Hierarchy

-   [ProcessDisplayedState](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/ProcessDisplayedState/)
    -   ProcessTreeDisplayedState Current type

## Properties

`public ImmutableDictionary<string, ProcessDisplayedState> SubprocessInfo { get; }` 

Gets the [ProcessDisplayedState](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/ProcessDisplayedState/) for each descendant subprocess, keyed by [ProcessInstance.SubprocessName](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/).

`public ImmutableList<string> SubprocessCurrentActivities { get; }` 

Gets the [ProcessInstance.CurrentActivityName](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/) values for the descendant subprocesses represented by [ProcessTreeDisplayedState.SubprocessInfo](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/ProcessTreeDisplayedState/).

## Methods

`public void AddSubprocess(ProcessInstance subprocessInstance, ProcessDisplayedState subprocessState)` 

Adds a descendant subprocess to [ProcessTreeDisplayedState.SubprocessInfo](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/ProcessTreeDisplayedState/) and [ProcessTreeDisplayedState.SubprocessCurrentActivities](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/ProcessTreeDisplayedState/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `subprocessInstance` | `ProcessInstance` | The [ProcessInstance](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/) that provides the [ProcessInstance.SubprocessName](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/) and [ProcessInstance.CurrentActivityName](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/) values to add. |
| `subprocessState` | `ProcessDisplayedState` | The [ProcessDisplayedState](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Designer/ProcessDisplayedState/) to associate with the [ProcessInstance.SubprocessName](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/) value from `subprocessInstance`. |

`public string GetSerializedValue()` 

Serializes this displayed process tree to JSON by using [ParametersSerializer.Serialize(object)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/ParametersSerializer/).

### Returns

| Type | Description |
| --- | --- |
| `String` | The serialized JSON string. |

## Remarks
