Detailed Description
template<class T>
class mrpt::bayes::CParticleFilterData< T >
This template class declares the array of particles and its internal data, managing some memory-related issues and providing an easy implementation of virtual methods required for implementing a CParticleFilterCapable.
See also the methods in the base class CParticleFilterDataImpl<>.
Since CProbabilityParticle implements all the required operators, the member "m_particles" can be safely copied with "=" or copy constructor operators and new objects will be created internally instead of copying the internal pointers, which would lead to memory corruption.
