Does ReflectionProperty::setAccessible make the property forever accessible?

I would like to have a private property in a class, and be able to set it with another, via a ReflectionClass.

I know that if I create ReflectionProperties of the class' properties, I can set them to accessible, and then set their values.

However, if I set the property to accessible, does it become accessible everywhere (like a public property), or is it just in the context of the ReflectionProperty?
