stxxl::vector_bufreader_iterator< VectorBufReaderType > Class Template Reference

Detailed Description

template<typename VectorBufReaderType>
class stxxl::vector_bufreader_iterator< VectorBufReaderType >

Adapter for vector_bufreader to match iterator requirements of C++11 range-based loop construct.

Since vector_bufreader itself points to only one specific item, this iterator is merely a counter facade. The functions operator*() and operator++() must only be called when it is in sync with the bufreader object. This is generally only the case for an iterator constructed with begin() and then advanced with operator++(). The class checks this using asserts(), the operators will fail if used wrong.
