## Methods

`public bool Equals(ActorDefinition x, ActorDefinition y)` 

Determines whether two [ActorDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActorDefinition/) instances have equal actor names.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `x` | `ActorDefinition` | The first [ActorDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActorDefinition/) to compare. |
| `y` | `ActorDefinition` | The second [ActorDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActorDefinition/) to compare. |

### Returns

| Type | Description |
| --- | --- |
| `Boolean` | [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) if `x` and `y` have equal actor names; otherwise, [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool). |

### Exceptions

| Type | Description |
| --- | --- |
| `NullReferenceException` | `x` or `y` is [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |

### Remarks

Actor names are compared case-sensitively.

`public int GetHashCode(ActorDefinition codeh)` 

Returns a hash code for an [ActorDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActorDefinition/) based on its actor name.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `codeh` | `ActorDefinition` | The [ActorDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActorDefinition/) for which to calculate a hash code. |

### Returns

| Type | Description |
| --- | --- |
| `Int32` | A hash code derived from the actor name of `codeh`. |

### Exceptions

| Type | Description |
| --- | --- |
| `NullReferenceException` | `codeh` or its actor name is [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |
