Properties

Name Value Summary
And ConstraintExpression
Returns a ConstraintExpression by appending And to the current constraint.
Inherited from Constraint
Arguments object[]
Arguments provided to this Constraint, for use in formatting the description.
Inherited from Constraint
Builder ConstraintBuilder
A ConstraintBuilder holding this constraint. If not null the constraint is under construction.
Inherited from Constraint
Description string
The Description of what this constraint tests, for use in messages and in the ConstraintResult.
DisplayName string
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.
Inherited from Constraint
IgnoreCase CollectionItemsEqualConstraint
Flag the constraint to ignore case and return self.
IgnoringCase bool
Get a flag indicating whether the user requested us to ignore case.
Or ConstraintExpression
Returns a ConstraintExpression by appending Or to the current constraint.
Inherited from Constraint
UsingExternalComparer bool
Get a flag indicating whether any external comparers are in use.
With ConstraintExpression
Returns a ConstraintExpression by appending And to the current constraint.

Methods

Name Value Summary
ApplyConstraint<T>(ActualValueDelegate<T>) ConstraintResult
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.
Inherited from Constraint
ApplyConstraint<T>(T) ConstraintResult
Test whether the constraint is satisfied by a given value
Inherited from CollectionConstraint
ApplyConstraint<T>(T) ConstraintResult
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.
Inherited from Constraint
ApplyTo<T>(ActualValueDelegate<T>) ConstraintResult
Validates the ActualValueDelegate and applies the constraint to the value it returns.
Inherited from Constraint
ApplyTo<T>(T) ConstraintResult
Validates the actual value argument and applies the constraint to it, returning a ConstraintResult.
Inherited from Constraint
ApplyTo<T>(T) ConstraintResult
Validates the actual value argument and applies the constraint to it, returning a ConstraintResult.
Inherited from Constraint
GetStringRepresentation() string
Returns the string representation of this constraint
Inherited from Constraint
IsEmpty(IEnumerable) bool
Determines whether the specified enumerable is empty.
Inherited from CollectionConstraint
static
ItemsEqual(object, object) bool
Compares two collection members for equality
Match(IEnumerable) bool
Check that all items are unique.
OriginalAlgorithm(IEnumerable) bool
Tally(IEnumerable) CollectionTally
Return a new CollectionTally for use in making tests
ToString() string
Default override of ToString returns the constraint DisplayName followed by any arguments within angle brackets.
Inherited from Constraint
TryFastAlgorithm(IEnumerable) bool?
Using(IComparer) CollectionItemsEqualConstraint
Flag the constraint to use the supplied IComparer object.
Using(IEqualityComparer) CollectionItemsEqualConstraint
Flag the constraint to use the supplied IEqualityComparer object.
Using<T>(Comparison<T>) CollectionItemsEqualConstraint
Flag the constraint to use the supplied Comparison object.
Using<T>(IComparer<T>) CollectionItemsEqualConstraint
Flag the constraint to use the supplied IComparer object.
Using<T>(IEqualityComparer<T>) CollectionItemsEqualConstraint
Flag the constraint to use the supplied IEqualityComparer object.
ValidateActualValue(object) void
