## Constructors

`public DeactivatedWorkflowActionProvider(IWorkflowActionProvider activatedActionProvider, Func<bool> getDisabled)` 

Initializes a new dynamically switchable wrapper around a workflow action provider.

### Parameters

## Remarks

The wrapper evaluates the predicate supplied to the constructor on every method call. When the predicate returns [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), the call is forwarded unchanged to the configured provider. When it returns [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), the configured provider is bypassed and the call is delegated to [EmptyWorkflowActionProvider.Value](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/EmptyWorkflowActionProvider/). Disabling the wrapper does not modify the configured provider.

While disabled, the wrapper exposes no action or condition names, synchronous actions perform no work, synchronous conditions return [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool), and asynchronous capability checks return [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool). Direct calls to the asynchronous execution methods are delegated to [EmptyWorkflowActionProvider](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime/EmptyWorkflowActionProvider/) and throw [NotImplementedException](https://learn.microsoft.com/dotnet/api/system.notimplementedexception).
