Package io.fury.format.row.binary.writer

Class BinaryArrayWriter

java.lang.Object
io.fury.format.row.binary.writer.BinaryWriter
io.fury.format.row.binary.writer.BinaryArrayWriter
public class BinaryArrayWriter extends BinaryWriter
Writer for binary array. See BinaryArray

Must call reset(numElements) before use this writer to writer an array every time.

Must call reset(numElements) before call fromPrimitiveArray methods, so we can write multiple primitive array into one binary array, and keep api consistent, rather call reset in fromPrimitiveArray.

      public BinaryArrayWriter(org.apache.arrow.vector.types.pojo.Field field)
      Must call reset before using writer constructed by this constructor.

    • BinaryArrayWriter

      public BinaryArrayWriter(org.apache.arrow.vector.types.pojo.Field field, BinaryWriter writer)
      Write data to writer's buffer.

  • Method Details

    • reset

      public void reset(int numElements)
      reset BinaryArrayWriter(ArrayType type, BinaryWriter writer) increase writerIndex, which increase writer's writerIndex, 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.
