Detailed Description

A simple container to hold the function pointer given by user for reading the serialized bitmaps.

Member Function Documentation

int ibis::index::bitmapReader::read ( uint64_t  b, uint64_t  c, ibis::fileManager::buffer< uint32_t > &  buf  )

inline

The main function to read the serialized bitmaps.

It assumes the bitmaps have been serialized and packed into a 1-D array of type uint32_t. This function intends to read c elements start with b. It uses the buffer buf to hold the in-memory data so that the memory can be resized as needed and tracked by the file manager.
