TEveChunkManager Class Reference

Vector-like container with chunked memory allocation.

Allocation chunk can accommodate fN atoms of byte-size fS each. The chunks themselves are TArrayCs and are stored in a std::vector<TArrayC*>. Holes in the structure are not supported, neither is removal of atoms. The structure can be Refit() to occupy a single contiguous array.
