Constructor Detail

BundleResourceHandler

public BundleResourceHandler()

Constructor for a bundle protocol resource URLStreamHandler.

BundleResourceHandler

public BundleResourceHandler(BundleEntry bundleEntry,
                             BaseAdaptor adaptor)

Method Detail

start

public void start(BundleContext context,
                  FrameworkAdaptor baseAdaptor)

Specified by:

start in interface ProtocolActivator

parseURL

protected void parseURL(URL url,
                        String str,
                        int start,
                        int end)

Parse reference URL.

Overrides:

parseURL in class URLStreamHandler

openConnection

protected URLConnection openConnection(URL url)
                                throws IOException

Establishes a connection to the resource specified by URL. Since different protocols may have unique ways of connecting, it must be overridden by the subclass.

Specified by:

openConnection in class URLStreamHandler

Parameters:

url - java.net.URL

Returns:

java.net.URLConnection

Throws:

IOException - thrown if an IO error occurs during connection establishment

findBundleEntry

protected abstract BundleEntry findBundleEntry(URL url,
                                               AbstractBundle bundle)
                                        throws IOException

Finds the bundle entry for this protocal. This is handled differently for Bundle.gerResource() and Bundle.getEntry() because getResource uses the bundle classloader and getEntry only used the base bundle file.

Parameters:

url - The URL to find the BundleEntry for.

Returns:

the bundle entry

Throws:

IOException

toExternalForm

protected String toExternalForm(URL url)

Converts a bundle URL to a String.

Overrides:

toExternalForm in class URLStreamHandler

Parameters:

url - the URL.

Returns:

a string representation of the URL.

hashCode

protected int hashCode(URL url)

Overrides:

hashCode in class URLStreamHandler

equals

protected boolean equals(URL url1,
                         URL url2)

Overrides:

equals in class URLStreamHandler

getHostAddress

protected InetAddress getHostAddress(URL url)

Overrides:

getHostAddress in class URLStreamHandler

hostsEqual

protected boolean hostsEqual(URL url1,
                             URL url2)

Overrides:

hostsEqual in class URLStreamHandler

sameFile

protected boolean sameFile(URL url1,
                           URL url2)

Overrides:

sameFile in class URLStreamHandler

checkAuthorization

protected boolean checkAuthorization(Bundle bundle)

getBundleClassLoader

protected static BaseClassLoader getBundleClassLoader(AbstractBundle bundle)
