Package org.apache.avro.io

Class OptimizedBinaryDecoder

  • public class OptimizedBinaryDecoder
extends org.apache.avro.io.BinaryDecoder
    This class is used to optimize bytes field decoding. It will wrap the original byte array as a byte buffer if the field type is 'bytes'(the default behavior in is to create a new byte array copy, which is not efficient. The reason to use package name: org.apache.avro.io since BinaryDecoder(byte[], int, int) is package-visible.
