In Perforce, that's called 'syncing' your workspace with the depot. If you 
were using the Perforce command line client you'd run:

 p4 sync

or possibly

 p4 sync -f

to force the sync even if Perforce thinks you already have the files in 

In P4Perl that becomes:



 $p4->Sync( "-f" );

Good luck with the integration!
