# Class ExpressionsCompilerOptions

OptimaJet.Workflow.Core.CodeActions.ExpressionsCompilerOptions

Configures batch-compilation concurrency and optional garbage collection after compiled delegates are created by [ExpressionsCompiler](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/ExpressionsCompiler/).

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

```csharp
public class ExpressionsCompilerOptions
```

## Properties

`public int DegreeOfParallelism { get; set; }` 

Gets or sets the maximum number of transitions processed concurrently when [ExpressionsCompiler.CompileExpressions(ProcessDefinition)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/ExpressionsCompiler/) or [ExpressionsCompiler.CompileSubprocessNameGetters(ProcessDefinition)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/ExpressionsCompiler/) compiles delegates for a process scheme.

`public bool ForceGarbageCollection { get; set; }` 

Gets or sets whether [GC.Collect()](https://learn.microsoft.com/dotnet/api/system.gc.collect#system-gc-collect) is invoked after each expression delegate is successfully compiled.

`public static ExpressionsCompilerOptions Default { get; }` 

Gets the shared mutable options instance used as the initial value of [ExpressionsCompiler.Options](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/ExpressionsCompiler/).

### Remarks

Changes made to this instance are retained and affect [ExpressionsCompiler.Options](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.CodeActions/ExpressionsCompiler/) while it references the same instance.

`public static ExpressionsCompilerOptions Forced { get; }` 

Gets the shared mutable preset intended to reduce peak memory usage by compiling one transition delegate at a time and requesting a garbage-collection cycle after each compilation.

### Remarks

Changes made to this shared instance are retained for subsequent uses.
