Exception handling in Iterable
- by Maas
Is there any way of handling -- and continuing from -- an exception in an iterator while maintaining the foreach syntactic sugar?
I've got a parser that iterates over lines in a file, handing back a class-per-line. Occasionally lines will be syntactically bogus, but that doesn't necessarily mean that we shouldn't keep reading the file.
My parser implements Iterable, but dealing with the potential exceptions means writing
for (Iterator iter = myParser.iterator(); iter.hasNext(); ) {
try {
MyClass myClass = iter.next();
// .. do stuff ..
} catch (Exception e) {
// .. do exception stuff ..
}
}
.. nothing wrong with that, but is there any way of getting exception handling on the implicit individual iter.next() calls in the foreach construct?
