Quick usage
We propose to explain the basis of this library. We have two entities: an
element to visit and a visitor, for example a node of a tree and a dumper. The
element to visit will implement the Hoa\Visitor\Element
interface and the
visitor will implement the Hoa\Visitor\Visit
interface. The first one will ask
to implement the accept
method in order to define what data it holds will be
visited. The second one will ask to implement the visit
method which will
contain the visitor computations. We will find several examples in Hoa
libraries.
