functions. If appropriate for your code , terminating the program may be an appropriate error handling response. Oth- erwise, consider a factory function or Init() method. Avoid Init() methods on objects with easier to understand, maintain, and optimize by the compiler. Further, such objects can be used with generic APIs that require pass-by-value, such as most containers, and they allow for additional flexibility this can result in a major performance improvement. • Rvalue references make it possible to write a generic function wrapper that forwards its arguments to another function, and works whether or not its arguments

Caught exceptions: not ignored Except as noted below, it is very rarely correct to do nothing in response to a caught exception. (Typical responses are to log it, or if it is considered “impos- sible”, Integer.parseInt(response); 16 return handleNumericResponse(i); } catch (NumberFormatException ok) { // it's not numeric; that's fine, just continue } return handleTextResponse(response); Exception: In

express the operation directly, without extra method calls. A function that uses default operators is generic. It can be used with any type that supports the operation. Cons: You can’t tell the type of objects before module globals and constants. Imports should be grouped with the order being most generic to least generic: • standard library imports • third-party imports • application-specific imports Within

considered for SIGMOD. Furthermore, after you submit a research paper to SIGMOD, you must await the response from SIGMOD and only re-submit elsewhere if your paper is rejected - or withdrawn at your request

for an S4 object would be to use objects directly in C++ code. A primary justification for an S4 generic/method would be to dispatch on two arguments. Avoid mixing S3 and S4: S4 methods ignore S3 inheritance
