# Interface ITransitionConditionBuilder

OptimaJet.Workflow.Core.Model.Builder.ITransitionConditionBuilder

Defines fluent operations for configuring a [ConditionType.Action](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionType/) condition in [TransitionDefinition.Conditions](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/TransitionDefinition/).

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

## Methods

`ITransitionConditionBuilder Inverted()` 

Sets [ConditionDefinition.ConditionInversion](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) to [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) for the current [ConditionDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/), causing its normally evaluated result to be negated.

### Returns

| Type | Description |
| --- | --- |
| `ITransitionConditionBuilder` | The same [ITransitionConditionBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionConditionBuilder/) instance for method chaining. |

`ITransitionConditionBuilder NotInverted()` 

Sets [ConditionDefinition.ConditionInversion](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) to [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) for the current [ConditionDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/), so its normally evaluated result is used without negation.

### Returns

| Type | Description |
| --- | --- |
| `ITransitionConditionBuilder` | The same [ITransitionConditionBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionConditionBuilder/) instance for method chaining. |

`ITransitionConditionBuilder ConditionParameter(string parameter)` 

Sets [ActionDefinitionReference.ActionParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActionDefinitionReference/) on the current [ConditionDefinition.Action](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) reference to `parameter`.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `parameter` | `String` | The parameter text to pass when the referenced condition is evaluated. |

### Returns

| Type | Description |
| --- | --- |
| `ITransitionConditionBuilder` | The same [ITransitionConditionBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionConditionBuilder/) instance for method chaining. |

`ITransitionConditionBuilder ConditionParameter(object parameter)` 

Serializes `parameter` to JSON by using [ParametersSerializer.Serialize(object)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/ParametersSerializer/) and sets [ActionDefinitionReference.ActionParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActionDefinitionReference/) on the current [ConditionDefinition.Action](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) reference to the result.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `parameter` | `Object` | The value to serialize as the referenced condition's parameter. |

### Returns

| Type | Description |
| --- | --- |
| `ITransitionConditionBuilder` | The same [ITransitionConditionBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionConditionBuilder/) instance for method chaining. |

`ITransitionConditionBuilder ReturnTrueOnPreExecution()` 

Sets [ConditionDefinition.ResultOnPreExecution](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) to [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), so the condition uses a fixed [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) result during pre-execution simulation without evaluating the condition logic referenced by [ConditionDefinition.Action](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) or applying [ConditionDefinition.ConditionInversion](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/).

### Returns

| Type | Description |
| --- | --- |
| `ITransitionConditionBuilder` | The same [ITransitionConditionBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionConditionBuilder/) instance for method chaining. |

`ITransitionConditionBuilder ReturnFalseOnPreExecution()` 

Sets [ConditionDefinition.ResultOnPreExecution](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) to [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), so the condition uses a fixed [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) result during pre-execution simulation without evaluating the condition logic referenced by [ConditionDefinition.Action](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) or applying [ConditionDefinition.ConditionInversion](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/).

### Returns

| Type | Description |
| --- | --- |
| `ITransitionConditionBuilder` | The same [ITransitionConditionBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionConditionBuilder/) instance for method chaining. |

`ITransitionConditionBuilder CalculateOnPreExecution()` 

Sets [ConditionDefinition.ResultOnPreExecution](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) to [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null), so the condition logic referenced by [ConditionDefinition.Action](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) is evaluated normally and [ConditionDefinition.ConditionInversion](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ConditionDefinition/) is applied during pre-execution simulation.

### Returns

| Type | Description |
| --- | --- |
| `ITransitionConditionBuilder` | The same [ITransitionConditionBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model.Builder/ITransitionConditionBuilder/) instance for method chaining. |
