NAME

6       GStreamer::Iterator
7

SYNOPSIS

9         foreach ($bin -> iterate_elements()) {
10           do_something($_);
11         }
12
13         my $iter = $bin -> iterate_elements();
14         while ($_ = $iter -> next()) {
15           do_something($_);
16         }
17

DESCRIPTION

19       There are two ways to use a GStreamer::Iterator.  The first is to use
20       normal Perl looping stuff:
21
22         foreach ($bin -> iterate_elements()) {
23           do_something($_);
24         }
25
26       This is very elegant and Perl-ish, but may also be a bit slower.
27
28       The alternative is to use the next method:
29
30         my $iter = $bin -> iterate_elements();
31         while ($_ = $iter -> next()) {
32           do_something($_);
33         }
34
35       This is hardly beautiful but avoids looping over the elements
36       unnecessarily and is thus faster.
37

METHODS

39   scalar = $iter->next
