public final class Map32TypeDecoder extends AbstractMapTypeDecoder
Decoder of AMQP Map value from a byte stream

  • Constructor Details

    • Map32TypeDecoder

      public Map32TypeDecoder()

  • Method Details

    • getTypeCode

      public int getTypeCode()
      Returns:
      the AMQP Encoding Code that this primitive type decoder can read.

    • readSize

      public int readSize(ProtonBuffer buffer) throws DecodeException
      Description copied from interface: MapTypeDecoder
      Reads the encoded size of the underlying Map type.
      Parameters:
      buffer - The buffer containing the encoded Map type.
      Returns:
      the size in bytes of the encoded Map.
      Throws:
      DecodeException - if an error occurs reading the value

    • readCount

      public int readCount(ProtonBuffer buffer) throws DecodeException
      Description copied from interface: MapTypeDecoder
      Reads the count of entries in the encoded Map.

      This value is the total count of all key values pairs, and should always be an even number as Map types cannot be unbalanced.

      Parameters:
      buffer - The buffer containing the encoded Map type.
      Returns:
      the number of elements that we encoded from the original Map.
      Throws:
      DecodeException - if an error occurs reading the value

    • readSize

      public int readSize(InputStream stream) throws DecodeException
      Description copied from interface: MapTypeDecoder
      Reads the encoded size of the underlying Map type.
      Parameters:
      stream - The InputStream containing the encoded Map type.
      Returns:
      the size in bytes of the encoded Map.
      Throws:
      DecodeException - if an error occurs reading the value

    • readCount

      public int readCount(InputStream stream) throws DecodeException
      Description copied from interface: MapTypeDecoder
      Reads the count of entries in the encoded Map.

      This value is the total count of all key values pairs, and should always be an even number as Map types cannot be unbalanced.

      Parameters:
      stream - The InputStream containing the encoded Map type.
      Returns:
      the number of elements that we encoded from the original Map.
      Throws:
      DecodeException - if an error occurs reading the value
