function TraversableContainsOnly::evaluate

Evaluates the constraint for parameter $other.

If $returnResult is set to false (the default), an exception is thrown in case of a failure. null is returned otherwise.

If $returnResult is true, the result of the evaluation is returned as a boolean value instead: true in case of success, false in case of a failure.
