public interface One2OneChannel
This defines the interface for a one-to-one Object channel.
The only methods provided are to obtain the ends of the channel, through which all reading and writing operations are done. Only an appropriate channel-end should be plugged into a process – not the whole channel. A process may use its external channels in one direction only – either for writing or reading.
Actual channels conforming to this interface are made using the relevant
static construction methods from Channel
.
Channels may be synchronising
,
buffered
,
poisonable
or both
(i.e. buffered and poisonable).
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.
The static methods of
Channel
construct channels with
either the default semantics or with buffering to user-specified capacity
and a range of blocking/overwriting policies.
Various buffering plugins are given in the org.jcsp.util package, but
careful users may write their own.
The Channel
methods also provide for the construction of
Poisonable
channels and for arrays of channels.
