Description

Interface Summary

ChannelDataStore

This is the interface for object channel plug-ins that define their buffering characteristics.

Class Summary

Buffer	This is used to create a buffered object channel that never loses data.
InfiniteBuffer	This is used to create a buffered object channel that always accepts and never loses any input.
OverFlowingBuffer	This is used to create a buffered object channel that always accepts input, discarding its last entered data if full.
OverWriteOldestBuffer	This is used to create a buffered object channel that always accepts input, overwriting its oldest data if full.
OverWritingBuffer	This is used to create a buffered object channel that always accepts input, overwriting its last entered data if full.
ZeroBuffer	This is used to create a zero-buffered object channel that never loses data.

Error Summary

BufferSizeError

This is thrown if an attempt is made to create some variety of buffered channel with a zero or negative sized buffer.

Package jcsp.util Description

This provides classes and interfaces to customise the semantics of Object channels.

By default, channels are zero-buffered and fully synchronised: both a reader and a writer have to be ready for a communication to proceed. Whoever gets to the communication point first has to wait for the other party.

This package provides a variety of classes conforming to the ChannelDataStore interface. These classes can be used as plug-ins to the static channel create methods to customise its semantics. Classes are provided for blocking FIFO buffers, overwriting buffers (losing either the newest or oldest data) and infinite (within the realms of your virtual memory) buffers.

Users may write and use their own implementations of the ChannelDataStore interface, but great care must be taken to specify its semantics. It should not normally be necessary to do this.
