public interface One2OneChannel

This implements a one-to-one object channel.

Description

One2OneChannelImpl implements a one-to-one object channel. Multiple readers or multiple writers are not allowed -- these are catered for by Any2OneChannel, One2AnyChannel or Any2AnyChannel.

The reading process may ALT on this channel. The writing process is committed (i.e. it may not back off).

The default semantics of the channel is that of CSP -- i.e. it is zero-buffered and fully synchronised. The reading process must wait for a matching writer and vice-versa.

A factory pattern is used to create channel instances. The create methods of Channel allow creation of channels, arrays of channels and channels with varying semantics such as buffering with a user-defined capacity or overwriting with various policies. Standard examples are given in the org.jcsp.util package, but careful users may write their own.

Other static create methods allows the user to create fully initialised arrays of channels, including plug-ins if required.
