- Public Member Functions inherited from NUnit.Framework.Constraints.Constraint
virtual ConstraintResult ApplyTo< TActual > (ActualValueDelegate< TActual > del)
 Applies the constraint to an ActualValueDelegate that returns the value to be tested. The default implementation simply evaluates the delegate but derived classes may override it to provide for delayed processing. More...
 
virtual ConstraintResult ApplyTo< TActual > (ref TActual actual)
 Test whether the constraint is satisfied by a given reference. The default implementation simply dereferences the value but derived classes may override it to provide for delayed processing. More...
 
override string ToString ()
 Default override of ToString returns the constraint DisplayName followed by any arguments within angle brackets. More...

Detailed Description

TypeConstraint is the abstract base for constraints that take a Type as their expected value.

Constructor & Destructor Documentation

NUnit.Framework.Constraints.TypeConstraint.TypeConstraint ( Type  type,
string  descriptionPrefix 
)
inlineprotected

Construct a TypeConstraint for a given Type

Parameters
typeThe expected type for the constraint
descriptionPrefixPrefix used in forming the constraint description

Member Function Documentation

override ConstraintResult NUnit.Framework.Constraints.TypeConstraint.ApplyTo< TActual > ( TActual  actual)
inlinevirtual

Applies the constraint to an actual value, returning a ConstraintResult.

Parameters
actualThe value to be tested
Returns
A ConstraintResult

Implements NUnit.Framework.Constraints.Constraint.

abstract bool NUnit.Framework.Constraints.TypeConstraint.Matches ( object  actual)
protectedpure virtual

Apply the constraint to an actual value, returning true if it succeeds

Parameters
actualThe actual argument
Returns
True if the constraint succeeds, otherwise false.

Implemented in NUnit.Framework.Constraints.InstanceOfTypeConstraint, NUnit.Framework.Constraints.ExactTypeConstraint, NUnit.Framework.Constraints.AssignableFromConstraint, and NUnit.Framework.Constraints.AssignableToConstraint.
