Detailed Description

template<typename T, typename TT, typename U, typename C, template< typename > class V>
class sensor_msgs::impl::PointCloud2IteratorBase< T, TT, U, C, V >

Private base class for PointCloud2Iterator and PointCloud2ConstIterator T is the type of the value on which the child class will be templated TT is the type of the value to be retrieved (same as T except for constness) U is the type of the raw data in PointCloud2 (only uchar and const uchar are supported) C is the type of the pointcloud to intialize from (const or not) V is the derived class (yop, curiously recurring template pattern)
