IVerifierProvider Interface

Interface to be implemented to provide verifiers dynamically at run time.

Syntax

Visual Basic
C#

'Declaration
 
<InterfaceExportAttribute(ContractName="", ContractType=IdeaBlade.Validation.IVerifierProvider)>
Public Interface IVerifierProvider

'Usage
 
Dim instance As IVerifierProvider

[InterfaceExport(ContractName="", ContractType=IdeaBlade.Validation.IVerifierProvider)]
public interface IVerifierProvider

Remarks

You can include any number of IVerifierProvider implementations in your application. Verifier providers are automatically discovered as attributed verifiers are processed, but you may also call VerifierEngine.DiscoverVerifiers to force discovery of verifiers for the applicable type.

Example

public class EmployeeVerifierProvider : IVerifierProvider {

  public  IEnumerable<Verifier> GetVerifiers(Object verifierProviderContext) {
    // Return a few verifiers.
    yield return GetFirstNameVerifier();
    yield return GetLastNameVerifier();
  }

  private Verifier GetLastNameVerifier() {
    return new StringLengthVerifier(typeof(Employee), "LastName", true, 3, 15);
  }

  private Verifier GetFirstNameVerifier() {
    return new StringLengthVerifier(typeof(Employee), Employee.PathFor(e => e.FirstName), false, null, 50);
  }
  
}
