InvocationMiddleware Delegate

Definition

Namespace:

System.CommandLine.Invocation

Assembly:

System.CommandLine.dll

A delegate used for adding command handler invocation middleware.

public delegate System::Threading::Tasks::Task ^ InvocationMiddleware(InvocationContext ^ context, Func<InvocationContext ^, Task ^> ^ next);

public delegate System.Threading.Tasks.Task InvocationMiddleware(InvocationContext context, Func<InvocationContext,Task> next);

type InvocationMiddleware = delegate of InvocationContext * Func<InvocationContext, Task> -> Task

Public Delegate Function InvocationMiddleware(context As InvocationContext, next As Func(Of InvocationContext, Task)) As Task 

Parameters

context

InvocationContext

The context for the current invocation, which will be passed to each middleware and then to the command handler, unless a middleware short circuits it.

next

Func<InvocationContext,Task>

A continuation. Passing the incoming InvocationContext to it will execute the next middleware in the pipeline and, at the end of the pipeline, the command handler. Middleware can short circuit the invocation by not calling this continuation.

Return Value

Task
