Class BufferSizeError

  extended by java.lang.Throwable
      extended by java.lang.Error
          extended by org.jcsp.util.BufferSizeError
All Implemented Interfaces:

public class BufferSizeError
extends Error

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


Buffered channels must have (usually non-zero) positive sized buffers. The following constructions will all throw this Error:
   One2OneChannel c = Channel.one2one (new Buffer (-42));                 // must be >= 0
   One2OneChannel c = Channel.one2one (new OverFlowingBuffer (-42));      // must be > 0
   One2OneChannel c = Channel.one2one (new OverWriteOldestBuffer (-42));  // must be > 0
   One2OneChannel c = Channel.one2one (new OverWritingBuffer (-42));      // must be > 0
   One2OneChannel c = Channel.one2one (new InfiniteBuffer (-42));         // must be > 0
Zero-buffered non-overwriting channels are, of course, the default channel semantics. The following constructions are all legal and equivalent:
   One2OneChannel c = Channel.one2one ();
   One2OneChannel c = Channel.one2one (new ZeroBuffer ());    // less efficient
   One2OneChannel c = Channel.one2one (new Buffer (0));       // less efficient
No action should be taken to catch BufferSizeError. Application code generating it is in error and needs correcting.
