Detailed Description

template<typename _Tp>
class cv::Seq< _Tp >

Template Sequence Class derived from CvSeq

The class provides more convenient access to sequence elements, STL-style operations and iterators.

Note
The class is targeted for simple data types, i.e. no constructors or destructors are called for the sequence elements.
