# Namespace OptimaJet.Workflow.Core.Builder

## Classes

-   [ActivitiesTimeoutsBuildStep](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/ActivitiesTimeoutsBuildStep/)
    
    Creates timeout transitions for activities whose [ActivityDefinition.IdleTimeout](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityDefinition/) targets an activity or a state through [ActivityTimeoutType.SetActivity](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityTimeoutType/) or [ActivityTimeoutType.SetState](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ActivityTimeoutType/).
    
-   [BuildStep](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/BuildStep/)
    
    Represents a scheme build step in the process scheme preparation pipeline.
    
-   [BuildStepResult](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/BuildStepResult/)
    
    Represents the result of a build step execution.
    
-   [InlineSchemesStep](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/InlineSchemesStep/)
    
    Represents a build step that inlines referenced [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) instances by replacing [IInlineActivity](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/IInlineActivity/) points with their referenced definitions.
    
-   [SchemeInlineUtils](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/SchemeInlineUtils/)
    
    Provides helper methods for inlining data from one [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) into another.
    
-   [SubprocessStartInTimerQueueStep](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/SubprocessStartInTimerQueueStep/)
    
    Prepares fork-start subprocess transitions that run from the timer queue by routing them through a hidden intermediate activity and timer transition.
    
-   [WorkflowBuilder<TSchemeMedium>](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/WorkflowBuilder-TSchemeMedium/)
    
    Workflow builder that converts unparsed process schemes from `TSchemeMedium` into runtime [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) instances.
    

## Interfaces

-   [IWorkflowBuilder](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/IWorkflowBuilder/)
    
    Converts raw process scheme media into [ProcessDefinition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/ProcessDefinition/) instances and coordinates scheme loading, parsing, generation, and build-step execution.
    

## Enums

-   [BuildStepPosition](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/BuildStepPosition/)
    
    Specifies where a [BuildStep](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/BuildStep/) is executed relative to built-in system build steps.
    
-   [SchemeParsingType](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Builder/SchemeParsingType/)
    
    Indicates how a scheme parser should treat the input while parsing.
