The library is based on slightly modified source codes of nfdump v1.6.12. It supports reading and filtering of flow records exactly as nfdump does. Aggregation, statistics and writing of new files is not supported yet.
In addition to nfdump, the library allows to use several filters at once, in one pass over a file, which may reduce number of disk accesses significantly in many applications.
