Method Details
-
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
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 UnsignedInteger 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.
-
skipValue
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
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.
-
readSize
Description copied from interface:TypeDecoder
Reads the size in bytes of the encoded AMQP type from the given buffer and returns it. Since this methods advances the read position of the provided buffer the caller must either reset that based on a previous mark or they must read the primitive payload manually as the decoder would not be able to read the value as it has no retained state.- Parameters:
buffer
- the source of encoded data.state
- the current state of the decoder.- Returns:
- the size in bytes of the encoded primitive value.
-
readSize
Description copied from interface:StreamTypeDecoder
Reads the size in bytes of the encoded primitive from the givenInputStream
and returns it. Since this methods advances the read position of the provided stream the caller must either reset that based on a previous mark or they must read the primitive payload manually as the decoder would not be able to read the value as it has no retained state.- Parameters:
stream
- the source of encoded data.state
- the current state of the decoder.- Returns:
- the size in bytes of the encoded primitive value.
