Interface BinaryWriter

All Known Implementing Classes:
BinaryArrayWriter, BinaryRowWriter
@Internal public interface BinaryWriter
Writer to write a composite data format, like row, array. 1. Invoke reset(). 2. Write each field by writeXX or setNullAt. (Same field can not be written repeatedly.) 3. Invoke complete().
