Interface IHasFailureMessageUsageCriteria

An object which can use custom logic to determine whether it may be used to provide a failure message.

Namespace: CSF.Validation.Messages

Assembly: CSF.Validation.Abstractions.dll

Syntax

public interface IHasFailureMessageUsageCriteria

Remarks

This interface is only useful when combined with one of the failure-message-provision interfaces:

Generally, using FailureMessageStrategyAttribute is a superior and more performant mechanism for selecting an appropriate message-provider class. However, for situations where that attribute alone is insufficent and custom/arbitrary logic must be used to determine whether a class may provide a message or not, this interface may be implemented and the CanGetFailureMessage(ValidationRuleResult) method used to provide that logic.

You are encouraged to read more about how validation message providers are used and selected at the documentation relating to message providers.
