Detailed Description

A lightweight path expression.

This exists so that paths can be cloned from the path legs of other paths without allocating heap memory to copy those legs into. This class does not own the memory of the Json_path_leg objects pointed to by Json_seekable_path::m_path_legs, it just points to Json_path_leg objects that belong to a Json_path instance.
