Package
Description
Handles the details of the result set loader implementation.
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.
Implementation of the vector writers.
This package provides a "dummy" set of writers.

Classes in org.apache.drill.exec.vector.accessor.writer used by org.apache.drill.exec.physical.resultSet.implClassDescriptionAbstract base class for the object layer in writers.Implementation for a writer for a tuple (a row or a map.) Provides access to each column using either a name or a numeric index.Listener (callback) to handle requests to add a new column to a tuple (row or map).List writer, which is basically an array writer, with the addition that each list element can be null.Writer to a union vector.Internal interface used to control the behavior of writers.Listener (callback) for vector overflow events.
