This class deserializes a serialization format into a row of a VectorizedRowBatch.
The caller provides the hive type names and output column numbers in the order desired to
This class uses an provided DeserializeRead object to directly deserialize by reading
field-by-field from a serialization format into the primitive values of the VectorizedRowBatch.
public int initConversion(TypeInfo targetTypeInfos,
Initialize for converting the source data type that are going to be read with the
DeserializedRead interface passed to the constructor to the target data types desired in
No projection -- the column range 0 .. count-1
where count is the minimum of the target data type array size, included array size,
and source data type array size.
the minimum count described above is returned. That is, the number of columns
that will be processed by deserialize.
