Re^4: How to get array elements from reference ?

[manishrathi]

I want to print content of the array. I have used following code for that

use TeamSite::WFsystem ;

$system = new TeamSite::WFsystem() ;

@jobs = $system->GetActiveWorkflows();

foreach $job (@jobs){

print "$job \n" ;

}

why am I still getting reference to array printed out ?

Since numerous people have told you already that ->GetActiveWorkflows() returns an arrayref instead of an array, here's the code that does something useful with that:


use TeamSite::WFsystem ;
$system = new TeamSite::WFsystem() ;
my $ar_jobs = $system->GetActiveWorkflows();
foreach my $job (@{$ar_jobs}){
  print "$job \n" ;
}

Assuming that $job will contain something printable, of course.
@{$ar_jobs} dereferences the arrayreference, which gives you the array that $ar_jobs references to. I usually prefix my arrayref and hashref variables with ar_ and hr_ respectively, so I can easily see what kind of reference I'm dealing with. This is not required, but imo easier to spot.

Because it seems that ->GetActiveWorkflows returns an array reference and not an array. Simply assigning to an array does not make the function return an array.
