Perllace has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks, This is my perl problem I have a script something like
$object1 = $ABC->Find('test1'); #Then I want to call a subroutine called CheckResult in Report->CheckResult($object,”Finding the value”); #In another case I want to report if a particular command #was execute +d, so I do something like this.. Report->CheckResult($ABC->Command(100,100),”Performing the command”);
Now in
sub CheckResult { my ($result,$information) = @_; #Now, I need something like this .. If( $result->isa(‘MyException’)) { #Some code to create the report } }
How do I use exception class and how to check if an exception is raised,and if so perform the task necessary..?? Thanks, Perllace

    You don't tell us what concept of "structured exception" you are using. If you are using one of the modules on CPAN, like Exception::Class or Exception, have you looked at the documentation?

    If you think implementing your own mechanism makes sense, take a look at eval and/or Try::Tiny.

    As an aside, the code you posted does not compile. Perl does not like the kinds of quotes you use:

    ”Performing the command” # should be "Performing the command" ‘MyException’ # should be 'MyException'
      Hi Corion I think Exception::Class will suit my need.. how do i use it??
