            that this state contains into the attributes implementations of the targetStream.
            The targetStream must contain a corresponding instance for each argument
            contained in this state (e.g. it is not possible to restore the state of
            an AttributeSource containing a TermAttribute into a AttributeSource using
            a Token instance as implementation).
            
            Note that this method does not affect attributes of the targetStream
            that are not contained in this state. In other words, if for example
            the targetStream contains an OffsetAttribute, but this state doesn't, then
            the value of the OffsetAttribute remains unchanged. It might be desirable to
            reset its value to the default, in which case the caller should first
            call {@link TokenStream#ClearAttributes()} on the targetStream.
