public class BufferSizeError extends java.lang.Error
This is thrown if an attempt is made to create some variety of buffered channel with a zero or negative sized buffer.Description
Buffered channels must have (usually non-zero) positive sized buffers. The following constructions will all throw thisError
: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.- See Also:
