# Class ProcessTimerEntity

OptimaJet.Workflow.Core.Entities.ProcessTimerEntity

Represents a persistence entity that stores a scheduled [TimerDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TimerDefinition/) for an [ProcessInstance](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/).

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

## Properties

`public Guid Id { get; set; }` 

Gets or sets the persisted timer identifier.

`public Guid ProcessId { get; set; }` 

Gets or sets the identifier of the process instance that owns the timer, as exposed by [ProcessInstance.ProcessId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/).

`public Guid RootProcessId { get; set; }` 

Gets or sets the identifier of the root process instance in the owning process tree, as exposed by [ProcessInstance.RootProcessId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/).

`public string Name { get; set; }` 

Gets or sets the persisted timer name corresponding to [BaseDefinition.Name](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/BaseDefinition/) on the scheduled [TimerDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TimerDefinition/).

`public DateTime NextExecutionDateTime { get; set; }` 

Gets or sets the date and time at which the persisted timer is next scheduled to execute.

`public bool Ignore { get; set; }` 

Gets or sets a value indicating whether the timer is excluded from selection for execution.

`public string TenantId { get; set; }` 

Gets or sets the tenant identifier associated with the owning process instance, as exposed by [ProcessInstance.TenantId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessInstance/).

## Methods

`public object GetValue(string key)` 

Gets the value of the property identified by the specified key.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `key` | `String` | The name of a supported public property declared by [ProcessTimerEntity](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/). |

### Returns

| Type | Description |
| --- | --- |
| `Object` | The property value identified by `key`. |

### Exceptions

| Type | Description |
| --- | --- |
| `ColumnNotExistsException` | `key` does not identify a supported property. |

`public void SetValue(string key, object value)` 

Sets the value of the property identified by the specified key.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `key` | `String` | The name of a supported public property declared by [ProcessTimerEntity](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/). |
| `value` | `Object` | The value to assign to the property identified by `key`. The expected type is [Guid](https://learn.microsoft.com/dotnet/api/system.guid) for [ProcessTimerEntity.Id](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/), [ProcessTimerEntity.ProcessId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/), and [ProcessTimerEntity.RootProcessId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/); [DateTime](https://learn.microsoft.com/dotnet/api/system.datetime) for [ProcessTimerEntity.NextExecutionDateTime](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/); [bool](https://learn.microsoft.com/dotnet/api/system.boolean) for [ProcessTimerEntity.Ignore](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/); and [string](https://learn.microsoft.com/dotnet/api/system.string) for [ProcessTimerEntity.Name](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/) and [ProcessTimerEntity.TenantId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Entities/ProcessTimerEntity/). |

### Exceptions

| Type | Description |
| --- | --- |
| `ColumnNotExistsException` | `key` does not identify a supported property. |
