public class One2OneChannelInt
extends AltingChannelInt

Description

The One2OneChannelInt is an implementation of an AltingChannelInt which is safe to use with only one Reading Process and one Writing Process. If either more than one reader or writer is using the ChannelInt data may either be lost or read from the ChannelInt more than once. In some cases it may cause the ChannelInt to be left in an unstable state.

This implementation of the ChannelInt uses Objects which conform to the ChannelDataStoreInt interface to store the data sent across the ChannelInt. This enables the storage policy to be defined when the channel is constructed. Also system constructors can define their own storage types.

This class also defines two static methods that can be used to create an array of One2OneChannelInt. The first of the two can be used to create an array with the default ChannelDataStoreInt and the second allows the type of the ChannelDataStoreInt to be specified.
