            [class] => Company
        )

    [1] => ReflectionClassConstant Object

        (
            [name] => IS_IMPLICIT_ABSTRACT
            [class] => ReflectionClass
        )

    [1] => ReflectionClassConstant Object
        (
            [name] => IS_EXPLICIT_ABSTRACT
            [class] => ReflectionClass
        )

    [2] => ReflectionClassConstant Object
        (
