Description
The "row set model" provides a "dual" of the vector structure used to create,
allocate and work with a collection of vectors.
Implementation of a row set model for hyper-batches.
This set of classes models the structure of a batch consisting
of single vectors (as contrasted with a hyper batch.) Provides tools
or metdata-based construction, allocation, reading and writing of
the vectors.
Provides a set of tools to work with row sets.
Provides a light-weight, simplified set of column readers and writers that
can be plugged into a variety of row-level readers and writers.
Provides the reader hierarchy as explained in the API package.
