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
