Update of /cvsroot/nice/Nice In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv18310 Modified Files: NEWS Log Message: Allow value returns in void methods.

For instance, + instead of: + + void add(int x) + { + if (x == 0) + { + buffer.append("ZERO\n"); + return; + } + ... + } + + one can now more simply write: + + void add(int x) + { + if (x == 0) + return buffer.append("ZERO\n"); + ... + } -- |
