multiple

[njw]

Hello. I am trying to catch multiple exceptions in a single catch block to avoid duplicate code. The following example illustrates the problem and solution in java. Does gosu support this functionality?

catch (IOException ex) {
     logger.log(ex);
     throw ex;
catch (SQLException ex) {
     logger.log(ex);
     throw ex;
}

In releases prior to Java SE 7, it is difficult to create a common method to eliminate the duplicated code because the variable ex has different types.

The following example, which is valid in Java SE 7 and later, eliminates the duplicated code:

catch (IOException|SQLException ex) {
    logger.log(ex);
    throw ex;
}

Thank you,
Nathan

Hi Nathan, and thanks for using Gosu.

Unfortunately we don't support the multi-catch syntax introduced in Java 7. Your code, in Gosu, would have to look like this:

try {
  foo = new Foo()
}
catch(ex : IOException) {
  //handle or throw
}
catch(ex : SQLException) {
  //handle or throw
}
catch(ex : Exception) {
  //handle or ??
}
finally {
  //...
}

Note that we can reuse the variable name since its scope is limited to the catch block declaring it.

Of course, if you would like to log an enhancement request on our Github home, we are happy to consider adding multi-catch: https://github.com/gosu-lang/gosu-lang/issues
