If I implement Input, I need to fill Buffer. What are guarantees about Buffer state. Do I need to flip it? Can I use it from start or I need to respect current position?

[Dominaezzz]

flip?

[Dominaezzz]

Buffer is random access. There no read/write position or state so to speak.

[Dominaezzz]

Are you talking about io-1 or io-2?

[altavir]

I am taking only about IO-2. I can do flip. The question if I am allowed to do it. For example if I already get half-full buffer, if I flip it, it could ged broken.

Buffer does not have position, but underlying ByteBuffer has and I have to use it to work with Channel.

[Dominaezzz]

Since it's multi-platform I don't think you should flip it or change it state, only change it's contents.

I use it only on JVM and only to use it with JVM channels.
