Examples with BundleFileWrapperChain org.eclipse.osgi.storage.bundlefile.BundleFileWrapperChain used on opensource projects

Example 1 with BundleFileWrapperChain

use of org.eclipse.osgi.storage.bundlefile.BundleFileWrapperChain in project rt.equinox.framework by eclipse.

the class Storage method wrapBundleFile.

public BundleFile wrapBundleFile(BundleFile bundleFile, Generation generation, boolean isBase) {
    // try creating a wrapper bundlefile out of it.
    List<BundleFileWrapperFactoryHook> wrapperFactories = getConfiguration().getHookRegistry().getBundleFileWrapperFactoryHooks();
    BundleFileWrapperChain wrapped = wrapperFactories.isEmpty() ? null : new BundleFileWrapperChain(bundleFile, null);
    for (BundleFileWrapperFactoryHook wrapperFactory : wrapperFactories) {
        BundleFileWrapper wrapperBundle = wrapperFactory.wrapBundleFile(bundleFile, generation, isBase);
        if (wrapperBundle != null && wrapperBundle != bundleFile)
            bundleFile = wrapped = new BundleFileWrapperChain(wrapperBundle, wrapped);
    }
    return bundleFile;
}

Example 2 with BundleFileWrapperChain

use of org.eclipse.osgi.storage.bundlefile.BundleFileWrapperChain in project rt.equinox.framework by eclipse.

the class ModuleClassLoader method createProtectionDomain.

/**

 * @param bundlefile The source bundlefile the domain is for.
 * @param domainGeneration the source generation for the domain
 * @return a ProtectionDomain which uses specified BundleFile and the permissions of the baseDomain
