      • isCurrent

        public boolean isCurrent()
        Description copied from interface: BundleWiring
        Returns true if this bundle wiring is the current bundle wiring. The bundle wiring for a bundle is the current bundle wiring if it is the most recent bundle wiring for the current bundle revision. All bundles with non-current, in use bundle wirings are considered removal pending.
        Specified by:
        isCurrent in interface BundleWiring
        Returns:
        true if this bundle wiring is the current bundle wiring; false otherwise.
      • isInUse

        public boolean isInUse()
        Description copied from interface: BundleWiring
        Returns true if this bundle wiring is in use. A bundle wiring is in use if it is the current wiring or if some other in use bundle wiring is dependent upon it. Once a bundle wiring is no longer in use, it is considered stale and is discarded by the framework.
        Specified by:
        isInUse in interface BundleWiring
        Returns:
        true if this bundle wiring is in use; false otherwise.
      • getResourceCapabilities

        public java.util.List<Capability> getResourceCapabilities​(java.lang.String namespace)
        Description copied from interface: BundleWiring
        Returns the capabilities provided by this wiring.

        Only capabilities considered by the resolver are returned. For example, capabilities with effective directive not equal to resolve are not returned.

        A capability may not be required by any wiring and thus there may be no wires for the capability.

        A wiring for a non-fragment resource provides a subset of the declared capabilities from the resource and all attached fragment resources. Not all declared capabilities may be provided since some may be discarded. For example, if a package is declared to be both exported and imported, only one is selected and the other is discarded.

        A wiring for a fragment resource with a symbolic name must provide exactly one osgi.identity capability.

        † The osgi.identity capability provided by attached fragment resource must not be included in the capabilities of the host wiring.

        This method returns the same value as BundleWiring.getCapabilities(String).

      • getResourceRequirements

        public java.util.List<Requirement> getResourceRequirements​(java.lang.String namespace)
        Description copied from interface: BundleWiring
        Returns the requirements of this wiring.

        Only requirements considered by the resolver are returned. For example, requirements with effective directive not equal to resolve are not returned.

        A wiring for a non-fragment resource has a subset of the declared requirements from the resource and all attached fragment resources. Not all declared requirements may be present since some may be discarded. For example, if a package is declared to be optionally imported and is not actually imported, the requirement must be discarded.

      • addDynamicWire

        public void addDynamicWire​(BundleWire wire)
      • getRevision

        public BundleRevision getRevision()
        Description copied from interface: BundleWiring
        Returns the bundle revision for the bundle in this bundle wiring. Since a bundle update can change the entries in a bundle, different bundle wirings for the same bundle can have different bundle revisions.

        The bundle object referenced by the returned BundleRevision may return different information than the returned BundleRevision since the returned BundleRevision may refer to an older revision of the bundle.

        Specified by:
        getRevision in interface BundleWiring
        Returns:
        The bundle revision for this bundle wiring.

      • getClassLoader

        public java.lang.ClassLoader getClassLoader()
        Description copied from interface: BundleWiring
        Returns the class loader for this bundle wiring. Since a bundle refresh creates a new bundle wiring for a bundle, different bundle wirings for the same bundle will have different class loaders.
        Specified by:
        getClassLoader in interface BundleWiring
        Returns:
        The class loader for this bundle wiring. If this bundle wiring is not in use or this bundle wiring is for a fragment revision, null will be returned.
      • getClassLoaderInternal

        private java.lang.ClassLoader getClassLoaderInternal()
      • findEntries

        public java.util.List<java.net.URL> findEntries​(java.lang.String path,
                                                        java.lang.String filePattern,
                                                        int options)
        Description copied from interface: BundleWiring
        Returns entries in this bundle wiring's bundle revision and its attached fragment revisions. This bundle wiring's class loader is not used to search for entries. Only the contents of this bundle wiring's bundle revision and its attached fragment revisions are searched for the specified entries.

        This method takes into account that the "contents" of this bundle wiring can have attached fragments. This "bundle space" is not a namespace with unique members; the same entry name can be present multiple times. This method therefore returns a list of URL objects. These URLs can come from different JARs but have the same path name. This method can either return only entries in the specified path or recurse into subdirectories returning entries in the directory tree beginning at the specified path.

        URLs for directory entries must have their path end with "/".

        Note: Jar and zip files are not required to include directory entries. URLs to directory entries will not be returned if the bundle contents do not contain directory entries.

        Specified by:
        findEntries in interface BundleWiring
        Parameters:
        path - The path name in which to look. The path is always relative to the root of this bundle wiring and may begin with "/". A path value of "/" indicates the root of this bundle wiring.
        filePattern - The file name pattern for selecting entries in the specified path. The pattern is only matched against the last element of the entry path. If the entry is a directory then the trailing "/" is not used for pattern matching. Substring matching is supported, as specified in the Filter specification, using the wildcard character ("*"). If null is specified, this is equivalent to "*" and matches all files.
        options - The options for listing resource names. See BundleWiring.FINDENTRIES_RECURSE. The method must ignore unrecognized options.
        Returns:
        An unmodifiable list of URL objects for each matching entry, or an empty list if no matching entry could be found, if this bundle wiring is for a fragment revision or if the caller does not have the appropriate AdminPermission[bundle,RESOURCE] and the Java Runtime Environment supports permissions. The list is ordered such that entries from the bundle revision are returned first followed by the entries from attached fragment revisions in attachment order. If this bundle wiring is not in use, null must be returned.

        Description copied from interface: BundleWiring
        Returns the names of resources visible to this bundle wiring's class loader. The returned names can be used to access the resources via this bundle wiring's class loader.
        • Only the resource names for resources in bundle wirings will be returned. The names of resources visible to a bundle wiring's parent class loader, such as the bootstrap class loader, must not be included in the result.
        • Only established wires will be examined for resources. This method must not cause new wires for dynamic imports to be established.
        Specified by:
        listResources in interface BundleWiring
        Parameters:
        path - The path name in which to look. The path is always relative to the root of this bundle wiring's class loader and may begin with "/". A path value of "/" indicates the root of this bundle wiring's class loader.
        filePattern - The file name pattern for selecting resource names in the specified path. The pattern is only matched against the last element of the resource path. If the resource is a directory then the trailing "/" is not used for pattern matching. Substring matching is supported, as specified in the Filter specification, using the wildcard character ("*"). If null is specified, this is equivalent to "*" and matches all files.
        options - The options for listing resource names. See BundleWiring.LISTRESOURCES_LOCAL and BundleWiring.LISTRESOURCES_RECURSE. This method must ignore unrecognized options.
        Returns:
        An unmodifiable collection of resource names for each matching resource, or an empty collection if no matching resource could be found, if this bundle wiring is for a fragment revision or if the caller does not have the appropriate AdminPermission[bundle,RESOURCE] and the Java Runtime Environment supports permissions. The collection is unordered and must contain no duplicate resource names. If this bundle wiring is not in use, null must be returned.

      • isClassExternal

        private boolean isClassExternal​(java.lang.Class clazz)
        Tries to determine whether the given class is part of the framework or not. Framework classes include everything in org.apache.felix.framework.* and org.osgi.framework.*. We also consider ClassLoader and Class to be internal classes, because they are inserted into the stack trace as a result of method overloading. Typically, ClassLoader or Class will be mixed in between framework classes or will be at the point where the class loading request enters the framework class loading mechanism, which will then be followed by either bundle or external code, which will then exit our attempt to determine if we should boot delegate or not. Other standard class loaders, like URLClassLoader, are considered external classes and should trigger boot delegation. This means that bundles can create standard class loaders to get access to boot packages, but this is the standard behavior of class loaders.
        Parameters:
        clazz - the class to determine if it is external or not.
        Returns:
        true if the class is external, otherwise false.
