Class BundleCollisionHook

  • All Implemented Interfaces:
    org.osgi.framework.hooks.bundle.CollisionHook, org.osgi.framework.hooks.bundle.EventHook, org.osgi.framework.hooks.bundle.FindHook
    public class BundleCollisionHook
extends java.lang.Object
implements org.osgi.framework.hooks.bundle.CollisionHook, org.osgi.framework.hooks.bundle.EventHook, org.osgi.framework.hooks.bundle.FindHook
    A bundle CollisionHook that contains a set of bundles that are allowed to collide with bundles that are about to be installed. This class also implements a FindHook to provide a consistent view of bundles such that the two sets of duplicate bundles are invisible to each other. In order to clean up when bundles are uninstalled, this is also a bundle EventHook. Thread safe

      • find

        public void find​(org.osgi.framework.BundleContext context,
                 java.util.Collection<org.osgi.framework.Bundle> bundles)
        Filters out the set of bundles that should not be visible to the bundle associated with the given context. If the given context represents one of the allowed duplicates, this method filters out all bundles that are duplicates of the allowed duplicates. Otherwise this method filters out the allowed duplicates, so they are not visible to other bundles.
