Syntax

public class DelayedConstraint : PrefixConstraint, IConstraint, IResolveConstraint

Constructors

DelayedConstraint(IConstraint, int)

Creates a new DelayedConstraint

Declaration

public DelayedConstraint(IConstraint baseConstraint, int delayInMilliseconds)

Parameters

Type	Name	Description
IConstraint	baseConstraint	The inner constraint to decorate
int	delayInMilliseconds	The time interval after which the match is performed

Exceptions

Type	Condition
InvalidOperationException	If the value of delayInMilliseconds is less than 0

DelayedConstraint(IConstraint, int, int)

Creates a new DelayedConstraint

Declaration

public DelayedConstraint(IConstraint baseConstraint, int delayInMilliseconds, int pollingIntervalInMilliseconds)

Parameters

Type	Name	Description
IConstraint	baseConstraint	The inner constraint to decorate
int	delayInMilliseconds	The time interval after which the match is performed, in milliseconds
int	pollingIntervalInMilliseconds	The time interval used for polling, in milliseconds

Exceptions

Type	Condition
InvalidOperationException	If the value of delayInMilliseconds is less than 0

Properties

Methods

ApplyToAsync<TActual>(Func<Task<TActual>>)

Applies the constraint to a delegate that returns the task. The default implementation simply evaluates the delegate and awaits the task but derived classes may override it to provide for delayed processing.

Declaration

public override Task<ConstraintResult> ApplyToAsync<TActual>(Func<Task<TActual>> taskDel)

Parameters

Type	Name	Description
Func<Task<TActual>>	taskDel

Returns

Type	Description
Task<ConstraintResult>

Type Parameters

Name	Description
TActual

Overrides

Constraint.ApplyToAsync<TActual>(Func<Task<TActual>>)

ApplyTo<TActual>(ActualValueDelegate<TActual>)

Test whether the constraint is satisfied by a delegate

Declaration

public override ConstraintResult ApplyTo<TActual>(ActualValueDelegate<TActual> del)

Parameters

Type	Name	Description
ActualValueDelegate<TActual>	del	The delegate whose value is to be tested

Returns

Type	Description
ConstraintResult	A ConstraintResult

Type Parameters

Name	Description
TActual

Overrides

Constraint.ApplyTo<TActual>(ActualValueDelegate<TActual>)

ApplyTo<TActual>(TActual)

Test whether the constraint is satisfied by a given value

Declaration

public override ConstraintResult ApplyTo<TActual>(TActual actual)

Parameters

Type	Name	Description
TActual	actual	The value to be tested

Returns

Type	Description
ConstraintResult	True for if the base constraint fails, false if it succeeds

Type Parameters

Name	Description
TActual

Overrides

Constraint.ApplyTo<TActual>(TActual)

ApplyTo<TActual>(ref TActual)

Test whether the constraint is satisfied by a given reference. Overridden to wait for the specified delay period before calling the base constraint with the dereferenced value.

Declaration

public override ConstraintResult ApplyTo<TActual>(ref TActual actual)

Parameters

Type	Name	Description
TActual	actual	A reference to the value to be tested

Returns

Type	Description
ConstraintResult	True for success, false for failure

Type Parameters

Name	Description
TActual

Overrides

Constraint.ApplyTo<TActual>(ref TActual)

GetStringRepresentation()

Returns the string representation of the constraint.

Declaration

protected override string GetStringRepresentation()

Returns

Type	Description
string

Overrides

Constraint.GetStringRepresentation()
