    • isJavaPrimitive

      public boolean isJavaPrimitive()
      Specified by:
      isJavaPrimitive in interface PrimitiveTypeDecoder<Byte>
      Overrides:
      isJavaPrimitive in class AbstractPrimitiveTypeDecoder<Byte>
      Returns:
      true if the type managed by this decoder is assignable to a Java primitive type.

    • getTypeClass

      public Class<Byte> getTypeClass()
      Returns:
      the Class that this decoder handles.

    • getTypeCode

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

    • readValue

      public Byte readValue(ProtonBuffer buffer, DecoderState state) throws DecodeException
      Description copied from interface: TypeDecoder
      Reads the next type from the given buffer and returns it.
      Parameters:
      buffer - the source of encoded data.
      state - the current state of the decoder.
      Returns:
      the next instance in the stream that this decoder handles.
      Throws:
      DecodeException - if an error is encountered while reading the next value.

    • readValue

      public Byte readValue(InputStream stream, StreamDecoderState state) throws DecodeException
      Description copied from interface: StreamTypeDecoder
      Reads the next type from the given buffer and returns it.
      Parameters:
      stream - the source of encoded data.
      state - the current state of the decoder.
      Returns:
      the next instance in the stream that this decoder handles.
      Throws:
      DecodeException - if an error is encountered while reading the next value.

    • readPrimitiveValue

      public byte readPrimitiveValue(ProtonBuffer buffer, DecoderState state) throws DecodeException
      Reads the primitive value from the given ProtonBuffer and returns it.
      Parameters:
      buffer - The ProtonBuffer where the primitive value should be read from.
      state - The DecoderState that can be used during decode of the value.
      Returns:
      the decoded primitive value.
      Throws:
      DecodeException - if an error occurs while reading the encoded value.

    • readPrimitiveValue

      public byte readPrimitiveValue(InputStream stream, StreamDecoderState state) throws DecodeException
      Reads the primitive value from the given InputStream and returns it.
      Parameters:
      stream - The InputStream where the primitive value should be read from.
      state - The DecoderState that can be used during decode of the value.
      Returns:
      the decoded primitive value.
      Throws:
      DecodeException - if an error occurs while reading the encoded value.

    • skipValue

      public void skipValue(ProtonBuffer buffer, DecoderState state) throws DecodeException
      Description copied from interface: TypeDecoder
      Skips over the bytes that compose the type this descriptor decodes.

      Skipping values can be used when the type is not used or processed by the application doing the decoding. An example might be an AMQP message decoder that only needs to decode certain parts of the message and not others.

      Parameters:
      buffer - The buffer that contains the encoded type.
      state - The decoder state.
      Throws:
      DecodeException - if an error occurs while skipping the value.

    • skipValue

      public void skipValue(InputStream stream, StreamDecoderState state) throws DecodeException
      Description copied from interface: StreamTypeDecoder
      Skips over the bytes that compose the type this descriptor decodes.

      Skipping values can be used when the type is not used or processed by the application doing the decoding. An example might be an AMQP message decoder that only needs to decode certain parts of the message and not others.

      Parameters:
      stream - The stream that contains the encoded type.
      state - The decoder state.
      Throws:
      DecodeException - if an error occurs while skipping the value.
