}
Python
In Python, the raise statement is similar to JavaScript and will stop processing unless an except statement
is used. See the python documentation.
s = Watch.GetJobInfo(9)
if not s:
raise NameError('Value cannot be empty')
else:
# Do something with Job Info 9!
Watch.Log("Job Info 9's value is: " + s,5)
Perl
In PERL, die() raises an exception and triggers the On Error tab, unless the unless command is used. See
the perl documentation.
$s = $Watch->GetJobInfo(9);
if (s = "") {
die "Value cannot be empty";
} else {
# Do something with Job Info 9!
$Watch->Log("Job Info 9's value is: " . $s,4);
}
Special Workflow Types
PlanetPress Workflow supports multiple input and output types, in so many different combinations that it
would be hard to give example processes for each possibility. However, some types of processes like PDF,
HTTPand SOAP are important enough to pay some attention to them.
This chapter will describe each of these special workflow types and give at least one example of an
implementation that uses them.
