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. getBufferState() returns true, if the value of the buffer semaphore is greater than zero and false otherwise.

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.
