Examples with SynchronousBundleListener org.osgi.framework.SynchronousBundleListener used on opensource projects

Example 1 with SynchronousBundleListener

use of org.osgi.framework.SynchronousBundleListener in project felix by apache.

the class BundleContextImpl method addBundleListener.

public void addBundleListener(BundleListener l) {
    checkValidity();
    // CONCURRENCY NOTE: This is a check-then-act situation, but
    // internally the event dispatcher double checks whether or not
    // the bundle context is valid before adding the service listener
    // while holding the event queue lock, so it will either succeed
    // or fail.
    Object sm = System.getSecurityManager();
    if (sm != null) {
        if (l instanceof SynchronousBundleListener) {
            ((SecurityManager) sm).checkPermission(new AdminPermission(m_bundle, AdminPermission.LISTENER));
        }
    }
    m_felix.addBundleListener(m_bundle, l);
}

Example 2 with SynchronousBundleListener

use of org.osgi.framework.SynchronousBundleListener in project felix by apache.

the class BundleContextImpl method removeBundleListener.

public void removeBundleListener(BundleListener l) {
    checkValidity();
    // CONCURRENCY NOTE: This is a check-then-act situation,
    // but we ignore it since the time window is small and
    // the result is the same as if the calling thread had
    // won the race condition.
    Object sm = System.getSecurityManager();
    if (sm != null) {
        if (l instanceof SynchronousBundleListener) {
            ((SecurityManager) sm).checkPermission(new AdminPermission(m_bundle, AdminPermission.LISTENER));
        }
    }
    m_felix.removeBundleListener(m_bundle, l);
