Method Detail

readValue
public Map<Object,Object> readValue(ProtonBuffer buffer, DecoderState state) throws DecodeException
Description copied from interface:TypeDecoder
Reads the next type from the given buffer and returns it.- Specified by:
readValue
in interfaceTypeDecoder<Map>
- 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.
-
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.
- Specified by:
skipValue
in interfaceTypeDecoder<Map>
- Parameters:
buffer
- The buffer that contains the encoded type.state
- The decoder state.- Throws:
DecodeException
- if an error occurs while skipping the value.
-
readValue
public Map<Object,Object> readValue(InputStream stream, StreamDecoderState state) throws DecodeException
Description copied from interface:StreamTypeDecoder
Reads the next type from the given buffer and returns it.- Specified by:
readValue
in interfaceStreamTypeDecoder<Map>
- 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.
-
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.
- Specified by:
skipValue
in interfaceStreamTypeDecoder<Map>
- Parameters:
stream
- The stream that contains the encoded type.state
- The decoder state.- Throws:
DecodeException
- if an error occurs while skipping the value.
