GStreamer::Iterator3pm

Object to retrieve multiple elements in a threadsafe way.

Usage

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

Overview

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
