CatBlockSource< BlockSource > Class Template Reference

Detailed Description

template<typename BlockSource>
class thrill::data::CatBlockSource< BlockSource >

CatBlockSource is a BlockSource which concatenates all Blocks available from a vector of BlockSources.

They are concatenated in order: first all Blocks from source zero, then from source one, etc.
