Ideally we need a better way to indicate an invalid input, as exception
handling is too expensive. Adding a check before process is one approach, but
as you said, it has performance penalty if all records are valid.
How about we use C-style function and return the result via parameter?. e.g.
```
class ToIntResult {
int res = 0;
boolean valid = true;
}
public void toInt(ToIntResult t) {
...
if (something wrong) {
t.valid = false;
}
...
t.res = xxx;
}
```
