Detailed Description

The function object must be derived from std::unary_function< IParticlePropertySvc::value_type ,bool > IParticlePropertySvc::value_type is a typedef that defines the internal service storage type that is returned when an iterator is dereferenced.

In this case it corresponds to pair< std::string, ParticleProperty* > as the ParticlePropertySvc stores all its data in a map. The string will be the map's key (usually the particle name) and the pointer is a pointer to the ParticleProperty object. The bool template argument states that operator() returns true or false.

The data is accessed in the following manner: const IParticlePropertySvc::value_type& pp_ref; std::string key = pp_ref.first; ParticleProperty* pp = pp_ref.second;
