Syntax

public class SomeItemsConstraint : PrefixConstraint, IConstraint, IResolveConstraint

Constructors

SomeItemsConstraint(IConstraint)

Construct a SomeItemsConstraint on top of an existing constraint

Declaration

public SomeItemsConstraint(IConstraint itemConstraint)

Parameters

Type	Name	Description
IConstraint	itemConstraint

Properties

DisplayName

The display name of this Constraint for use by ToString(). The default value is the name of the constraint with trailing "Constraint" removed. Derived classes may set this to another name in their constructors.

Declaration

public override string DisplayName { get; }

Property Value

Type	Description
string

Overrides

Constraint.DisplayName

Methods

ApplyTo<TActual>(TActual)

Apply the item constraint to each item in the collection, succeeding if any item succeeds.

Declaration

public override ConstraintResult ApplyTo<TActual>(TActual actual)

Parameters

Type	Name	Description
TActual	actual

Returns

Type	Description
ConstraintResult

Type Parameters

Name	Description
TActual

Overrides

Constraint.ApplyTo<TActual>(TActual)

Using(IComparer)

Flag the constraint to use the supplied IComparer object.

Declaration

public SomeItemsConstraint Using(IComparer comparer)

Parameters

Type	Name	Description
IComparer	comparer	The IComparer object to use.

Returns

Type	Description
SomeItemsConstraint	Self.

Using(IEqualityComparer)

Flag the constraint to use the supplied IEqualityComparer object.

Declaration

public SomeItemsConstraint Using(IEqualityComparer comparer)

Parameters

Type	Name	Description
IEqualityComparer	comparer	The IComparer object to use.

Returns

Type	Description
SomeItemsConstraint	Self.

UsingPropertiesComparer()

Enables comparing of instance properties.

Declaration

public SomeItemsConstraint UsingPropertiesComparer()

Returns

Type	Description
SomeItemsConstraint

Remarks

This allows comparing classes that don't implement IEquatable<T> without having to compare each property separately in own code.

Using<T>(IComparer<T>)

Flag the constraint to use the supplied IComparer<T> object.

Declaration

public SomeItemsConstraint Using<T>(IComparer<T> comparer)

Parameters

Type	Name	Description
IComparer<T>	comparer	The IComparer object to use.

Returns

Type	Description
SomeItemsConstraint	Self.

Type Parameters

Name	Description
T

Using<T>(IEqualityComparer<T>)

Flag the constraint to use the supplied IEqualityComparer<T> object.

Declaration

public SomeItemsConstraint Using<T>(IEqualityComparer<T> comparer)

Parameters

Type	Name	Description
IEqualityComparer<T>	comparer	The IComparer object to use.

Returns

Type	Description
SomeItemsConstraint	Self.

Type Parameters

Name	Description
T

Using<T>(Comparison<T>)

Flag the constraint to use the supplied Comparison<T> object.

Declaration

public SomeItemsConstraint Using<T>(Comparison<T> comparer)

Parameters

Type	Name	Description
Comparison<T>	comparer	The IComparer object to use.

Returns

Type	Description
SomeItemsConstraint	Self.

Type Parameters

Name	Description
T

Using<TActualCollectionElement, TExpected>(Func<TActualCollectionElement, TExpected, bool>)

Flag the constraint to use the supplied Func<T1, T2, TResult> object.

Declaration

public SomeItemsConstraint Using<TActualCollectionElement, TExpected>(Func<TActualCollectionElement, TExpected, bool> comparison)

Parameters

Type	Name	Description
Func<TActualCollectionElement, TExpected, bool>	comparison	The comparison function to use.

Returns

Type	Description
SomeItemsConstraint	Self.

Type Parameters

Name	Description
TActualCollectionElement	The type of the elements in the collection.
TExpected	The type of the expected value.
