Syntax

[PublicAPI]
public sealed class EmptySpecification<T> : ComplexSpecification<T>, 
    INegatableValidationSpecification<T>, IComplexSpecification<T>, IValidationSpecification<T>, 
    ILinqSpecification<T>, ILinqSpecification, ISpecification<T>, INegatableLinqSpecification<T>, 
    INegatableSpecification<T>, ISpecification

Remarks

Empty means:
  • Null reference
  • Empty string
  • Collection without elements
  • Object is equal to default value of T
