ImplementsInterface
final class ImplementsInterface extends AbstractConstraint
Constraint that accepts classes that implement given interface.
Traits
Implementation of an inheritance constraint class.
Methods
Evaluates the constraint for parameter $other. Returns true if the constraint is met, false otherwise.
Returns the description of the failure.
Returns short description of what we examine, e.g. 'impements interface'.
Returns short negated description of what we examine, e.g. 'does not impement interface'.
Checks if $subject may be used as an argument to inheritance().
Returns a custom string representation of the constraint object when it appears in context of an $operator expression.
Returns the description of the failure when this constraint appears in context of an $operator expression.
No description

final string
failureDescription(mixed $other)
Returns the description of the failure.
The beginning of failure messages is "Failed asserting that" in most cases. This method should return the second part of that sentence.

final protected string
toStringInContext(Operator $operator, mixed $role)
Returns a custom string representation of the constraint object when it appears in context of an $operator expression.
The purpose of this method is to provide meaningful descriptive string in context of operators such as LogicalNot. Native PHPUnit constraints are supported out of the box by LogicalNot, but externally developed ones had no way to provide correct strings in this context.
The method shall return empty string, when it does not handle customization by itself.
