Syntax

public class StartsWithConstraint : StringConstraint, IConstraint, IResolveConstraint

Constructors

Name Summary
StartsWithConstraint(string) Initializes a new instance of the StartsWithConstraint class.

Fields

Name Constant Value Summary
_caseInsensitive
Indicates whether tests should be case-insensitive
Inherited from StringConstraint

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
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 StringConstraint
Modify the constraint to ignore case in matching.
Inherited from StringConstraint
Or ConstraintExpression
Returns a ConstraintExpression by appending Or to the current constraint.
Inherited from Constraint
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 StringConstraint
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
Matches(string) bool
Test whether the constraint is matched by the actual value. This is a template method, which calls the IsMatch method of the derived class.
ToString() string
Default override of ToString returns the constraint DisplayName followed by any arguments within angle brackets.

ValidateActualValue(object) void
Inherited from StringConstraint
