    • decode

      public BsonNull decode(BsonReader reader, DecoderContext decoderContext)
      Description copied from interface: Decoder
      Decodes a BSON value from the given reader into an instance of the type parameter T.
      Specified by:
      decode in interface Decoder<BsonNull>
      Parameters:
      reader - the BSON reader
      decoderContext - the decoder context
      Returns:
      an instance of the type parameter T.
    • encode

      public void encode(BsonWriter writer, BsonNull value, EncoderContext encoderContext)
      Description copied from interface: Encoder
      Encode an instance of the type parameter T into a BSON value.
      Specified by:
      encode in interface Encoder<BsonNull>
      Parameters:
      writer - the BSON writer to encode into
      value - the value to encode
      encoderContext - the encoder context
    • getEncoderClass

      public Class<BsonNull> getEncoderClass()
      Description copied from interface: Encoder
      Returns the Class instance that this encodes. This is necessary because Java does not reify generic types.
      Specified by:
      getEncoderClass in interface Encoder<BsonNull>
      Returns:
      the Class instance that this encodes.
