Interface ICommandErrorHandler

Namespace

Assembly

Albatross.CommandLine.dll

public interface ICommandErrorHandler

Methods

Handle(params IEnumerable<Error>)

Called with one or more error conditions collected during command execution, from any ErrorSource — the command handler, option handlers, service resolution, or cancellation. Because several option handlers can fail in a single invocation, the errors arrive as a set. The handler's only job is to notify the user of the errors (e.g. print to stderr). Return a non-null exit code to override the default; return null to fall through to the default error exit code.

int? Handle(params IEnumerable<Error> errors)

Parameters

errors IEnumerable<Error>

Returns

int?

Remarks

Logging is not necessary here: each error is already logged at the catch site before this handler is invoked. The handler's job is only to notify the user of the error (e.g. print to stderr).
