Class BundleCollisionHook

java.lang.Object
com.yahoo.jdisc.core.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 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

    • filterCollisions

      public void filterCollisions(int operationType, org.osgi.framework.Bundle target, Collection<org.osgi.framework.Bundle> collisionCandidates)
      Removes duplicates of the allowed duplicate bundles from the given collision candidates.
      Specified by:
      filterCollisions in interface org.osgi.framework.hooks.bundle.CollisionHook

    • find

      public void find(org.osgi.framework.BundleContext context, 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.
      Specified by:
      find in interface org.osgi.framework.hooks.bundle.FindHook
