NUnit.Framework.Constraints.MessageWriter
MessageWriter is the abstract base for classes that write
constraint descriptions and messages in some form. The
class has separate methods for writing various components
of a message, allowing implementations to tailor the
presentation as needed.
namespace NUnit.Framework.Constraints
{
public abstract class CollectionConstraint : Constraint
{
protected CollectionConstraint();
protected CollectionConstraint(object arg);
protected static bool IsEmpty(IEnumerable enumerable);
protected abstract bool Matches(IEnumerable collection);
