Examples with BundleWire org.osgi.framework.wiring.BundleWire used on opensource projects

Example 1 with BundleWire

use of org.osgi.framework.wiring.BundleWire in project camel by apache.

the class Activator method canSee.

/**
     * Check if bundle can see the given class
     */
protected boolean canSee(Bundle bundle, Class<?> clazz) {
    if (bundle.getBundleId() == bundleId) {
        // Need extra handling of camel core as it does not import the api
        return true;

                return true;
            }
        }
    }
    // then we need to use a different canSee algorithm that works outside real OSGi
    if (bundle.getBundleId() > 0) {
        Bundle root = bundle.getBundleContext().getBundle(0);
