Detailed Description

template<class T, class R = void>
class te::common::BaseVisitable< T, R >

The root of all hierarchies that can be visited.

This class defines a pure virtual function that subclasses must implement in order to be visited.

This function may return values (see the R type in template declaration).

Requirements on types:

• T: the type of visitor;
• R: the return type for the accept method.
