Constructors

Name	Summary
ItemsConstraintExpression()	Create a new instance of ItemsConstraintExpression
ItemsConstraintExpression(ConstraintBuilder)	Create a new instance of ResolvableConstraintExpression, passing in a pre-populated ConstraintBuilder.

Properties

Name	Value	Summary
Builder	ConstraintBuilder	The ConstraintBuilder associated with this expression Inherited from ConstraintExpression
False	FalseConstraint	Returns a constraint that tests for False Inherited from ConstraintExpression
Items	ResolvableConstraintExpression	No-op property for readability.
Negative	LessThanConstraint<int>	Returns a constraint that tests for a negative value Inherited from ConstraintExpression
Null	NullConstraint	Returns a constraint that tests for null Inherited from ConstraintExpression
One	ItemsConstraintExpression	Returns a `ItemsConstraintExpression` which will apply the following constraint to only one member of the collection, and fail if none or more than one match occurs. Inherited from ConstraintExpression
Positive	GreaterThanConstraint<int>	Returns a constraint that tests for a positive value Inherited from ConstraintExpression
True	TrueConstraint	Returns a constraint that tests for True Inherited from ConstraintExpression
Unique	UniqueItemsConstraint	Returns a constraint that tests whether a collection contains all unique items. Inherited from ConstraintExpression
Zero	EqualConstraint<int>	Returns a constraint that tests if item is equal to zero Inherited from ConstraintExpression

Methods

Name	Value	Summary
Append(Constraint)	Constraint	Appends a constraint to the expression and returns that constraint, which is associated with the current state of the expression being built. Inherited from ConstraintExpression
Append(ConstraintOperator)	ConstraintExpression	Appends an operator to the expression and returns the resulting expression itself. Inherited from ConstraintExpression
Append(SelfResolvingOperator)	ResolvableConstraintExpression	Appends a self-resolving operator to the expression and returns a new ResolvableConstraintExpression. Inherited from ConstraintExpression
AtLeast<T>(T)	GreaterThanOrEqualConstraint<T>	Returns a constraint that tests whether the actual value is greater than or equal to the suppled argument Inherited from ConstraintExpression
AtMost<T>(T)	LessThanOrEqualConstraint<T>	Returns a constraint that tests whether the actual value is less than or equal to the suppled argument Inherited from ConstraintExpression
Contains(string)	ContainsConstraint<string>	Returns a new ContainsConstraint. This constraint will, in turn, make use of the appropriate second-level constraint, depending on the type of the actual argument. This overload is only used if the item sought is a string, since any other type implies that we are looking for a collection member. Inherited from ConstraintExpression
ContainsSubstring(string)	SubstringConstraint	Returns a constraint that succeeds if the actual value contains the substring supplied as an argument. Inherited from ConstraintExpression
EndsWith(string)	EndsWithConstraint	Returns a constraint that succeeds if the actual value ends with the substring supplied as an argument. Inherited from ConstraintExpression
EqualTo<T>(T)	EqualConstraint<T>	Returns a constraint that tests two items for equality Inherited from ConstraintExpression
EquivalentTo(IEnumerable)	CollectionEquivalentConstraint	Returns a constraint that tests whether the actual value is a collection containing the same elements as the collection supplied as an argument. Inherited from ConstraintExpression
Exactly(int)	ItemsConstraintExpression	Returns a ConstraintExpression, which will apply the following constraint to all members of a collection, succeeding only if a specified number of them succeed. Inherited from ConstraintExpression
GreaterThan<T>(T)	GreaterThanConstraint<T>	Returns a constraint that tests whether the actual value is greater than the suppled argument Inherited from ConstraintExpression
GreaterThanOrEqualTo<T>(T)	GreaterThanOrEqualConstraint<T>	Returns a constraint that tests whether the actual value is greater than or equal to the suppled argument Inherited from ConstraintExpression
InRange<T>(T, T)	RangeConstraint<T>	Returns a constraint that tests whether the actual value falls within a specified range. Inherited from ConstraintExpression
InstanceOf(Type)	InstanceOfTypeConstraint	Returns a constraint that tests whether the actual value is of the type supplied as an argument or a derived type. Inherited from ConstraintExpression
InstanceOf<T>()	InstanceOfTypeConstraint	Returns a constraint that tests whether the actual value is of the type supplied as an argument or a derived type. Inherited from ConstraintExpression
LessThan<T>(T)	LessThanConstraint<T>	Returns a constraint that tests whether the actual value is less than the suppled argument Inherited from ConstraintExpression
LessThanOrEqualTo<T>(T)	LessThanOrEqualConstraint<T>	Returns a constraint that tests whether the actual value is less than or equal to the suppled argument Inherited from ConstraintExpression
Matches(Regex)	RegexConstraint	Returns a constraint that succeeds if the actual value matches the regular expression supplied as an argument. Inherited from ConstraintExpression
Matches(string, RegexOptions)	RegexConstraint	Returns a constraint that succeeds if the actual value matches the regular expression supplied as an argument. Inherited from ConstraintExpression
SameAs<T>(T)	SameAsConstraint<T>	Returns a constraint that tests that two references are the same object Inherited from ConstraintExpression
StartsWith(string)	StartsWithConstraint	Returns a constraint that succeeds if the actual value starts with the substring supplied as an argument. Inherited from ConstraintExpression
TypeOf(Type)	ExactTypeConstraint	Returns a constraint that tests whether the actual value is of the exact type supplied as an argument. Inherited from ConstraintExpression
TypeOf<T>()	ExactTypeConstraint	Returns a constraint that tests whether the actual value is of the exact type supplied as an argument. Inherited from ConstraintExpression
