resumeAccept 函数的逻辑看不懂

public function resumeAccept()
{
    // Register a listener to be notified when server socket is ready to read.
    if (static::$globalEvent && true === $this->_pauseAccept && $this->_mainSocket) {
        if ($this->transport !== 'udp') {
            static::$globalEvent->add($this->_mainSocket, EventInterface::EV_READ, array($this, 'acceptConnection'));
        } else {
            static::$globalEvent->add($this->_mainSocket, EventInterface::EV_READ, array($this, 'acceptUdpConnection'));
        }
        $this->_pauseAccept = false;
    }
}

我怎么觉得是

if (static::$globalEvent && flase === $this->_pauseAccept && $this->_mainSocket) {
 这样才对 $this->_pauseAccept =ture 不是暂停的吗   都暂停了 还怎么进行
