Open Power Template supports advisory notifications on the output buffer state. They can help deciding, whether to open a new output buffer or using an existing one. Advisory output buffer states are a kind of semaphores. setBufferState() increments the value, if $state is true and decrements for false. The minimum semaphore value is 0. If it reaches this value, setBufferState('buffer', false) has no effect.

ob_start();
$tpl->setBufferState('buffer', true);
 
// ...
 
if(!$tpl->getBufferState('buffer'))
{
    ob_start();
    $tpl->setBufferState('buffer', true);
}
 
// ...
 
ob_end_flush();
$tpl->setBufferState('buffer', false);

Advisory output buffer states are mostly used in OPT caching systems.
