NAME

       GStreamer::Iterator -  Object to retrieve multiple elements in a threadsafe way.

SYNOPSIS

         foreach ($bin -> iterate_elements()) {
           do_something($_);
         }

         my $iter = $bin -> iterate_elements();
         while ($_ = $iter -> next()) {
           do_something($_);
         }

DESCRIPTION

       There are two ways to use a GStreamer::Iterator.  The first is to use normal Perl looping
       stuff:

         foreach ($bin -> iterate_elements()) {
           do_something($_);
         }

       This is very elegant and Perl-ish, but may also be a bit slower.

       The alternative is to use the next method:

         my $iter = $bin -> iterate_elements();
         while ($_ = $iter -> next()) {
           do_something($_);
         }

       This is hardly beautiful but avoids looping over the elements unnecessarily and is thus
       faster.

METHODS

   scalar = $iter->next
