Detailed Description

Object that handles loading/storing a PlannerData object to/from a binary stream. Serialization of vertices and edges is performed using the Boost archive method serialize. Derived vertex/edge classes are handled, presuming those classes implement the serialize method.

Remarks
Since the serialize method for vertices and edges is templated, it cannot be virtual. To serialize a derived class AND the base class data, a special call can be invoked inside of serialize that instructs the serializer to also serialize the base class. The derived class must also have a GUID exposed to the serializer for proper deserialization at runtime. This is performed with the BOOST_CLASS_EXPORT macro. An example of these items is given below:
#include <boost/serialization/export.hpp>
class MyVertexClass : public ompl::base::PlannerDataVertex
{
// ---SNIP---
template <class Archive>
void serialize(Archive & ar, const unsigned int version)
{
ar & boost::serialization::base_object<ompl::base::PlannerDataVertex>(*this);
// ... (The other members of MyVertexClass)
}
};
BOOST_CLASS_EXPORT(MyVertexClass);
