C++ (Cpp) HashSet::takeAny Examples

Example #1

File: MediaSession.cpp Project: TaleAi/webkit

void MediaSession::safelyIterateActiveMediaElements(std::function<void(HTMLMediaElement*)> handler)
{
    ASSERT(!m_iteratedActiveParticipatingElements);

    HashSet<HTMLMediaElement*> activeParticipatingElementsCopy = m_activeParticipatingElements;
    m_iteratedActiveParticipatingElements = &activeParticipatingElementsCopy;

    while (!activeParticipatingElementsCopy.isEmpty())
        handler(activeParticipatingElementsCopy.takeAny());

    m_iteratedActiveParticipatingElements = nullptr;
}
