<encoder-duplex> ( stream-in stream-out encoding -- duplex )

Vocabulary

io.streams.duplex

Inputs

stream-in	an input stream
stream-out	an output stream
encoding	an encoding descriptor

Outputs

duplex

an encoded duplex stream

Word description

Wraps the given streams in an encoder or decoder stream, and puts them together in a duplex stream for input and output. If either input stream is already encoded, that encoding is stripped off before it is reencoded. The encoding descriptor must conform to the Encoding protocol.

Notes

Calling this word directly is not necessary in most cases. Higher-level words call it automatically.
