Method Details

encode

public void encode(org.apache.qpid.proton.message.Message value,
 OutputStream outStream)
            throws CoderException,
IOException

Description copied from class: Coder

Encodes the given value of type T onto the given output stream. Multiple elements can be encoded next to each other on the output stream, each coder should encode information to know how many bytes to read when decoding. A common approach is to prefix the encoding with the element's encoded length.

Specified by:

encode in class Coder<org.apache.qpid.proton.message.Message>

Throws:

CoderException - if the value could not be encoded for some reason

IOException - if writing to the OutputStream fails for some reason

decode

public org.apache.qpid.proton.message.Message decode(InputStream inStream)
                                              throws CoderException,
IOException

Description copied from class: Coder

Decodes a value of type T from the given input stream in the given context. Returns the decoded value. Multiple elements can be encoded next to each other on the input stream, each coder should encode information to know how many bytes to read when decoding. A common approach is to prefix the encoding with the element's encoded length.

Specified by:

decode in class Coder<org.apache.qpid.proton.message.Message>

Throws:

CoderException - if the value could not be decoded for some reason

IOException - if reading from the InputStream fails for some reason
