Class BinaryRowWriter

java.lang.Object

org.apache.fury.format.row.binary.writer.BinaryWriter

org.apache.fury.format.row.binary.writer.BinaryRowWriter

public class BinaryRowWriter
extends BinaryWriter

Writer to write data into buffer using row format, see BinaryRow.

Must call reset() before use this writer to write a nested row.

Must call reset(buffer)/reset(buffer, offset) before use this writer to write a new row.

Method Detail

getSchema

public org.apache.arrow.vector.types.pojo.Schema getSchema()

reset

public void reset()

Call reset() before write nested row to buffer

reset BinaryRowWriter(schema, writer) increase writerIndex, which increase writer's writerIndex, so we need to record writer's writerIndex before call reset, so we can call writer's setOffsetAndSize(int ordinal, int absoluteOffset, int size). Reset will change writerIndex, please use it very carefully
