isResolved
public static boolean isResolved(org.osgi.framework.Bundle bundle) Based on the constant field values, if it is bigger than the RESOLVED status value, the bundle has been resolved by the framework- Parameters:
bundle
-- Returns:
- true if the bundle is resolved, or false if not.
-
resolve
public static void resolve(org.osgi.framework.Bundle bundle) resolve method will try to load the Object.class, the behavior triggers a resolved request to the OSGI framework.- Parameters:
bundle
-
-
canStart
public static boolean canStart(org.osgi.framework.Bundle bundle) If the bundle fulfills the conditions below, it could be started a. Not in the UNINSTALLED status. b. Not in the STARTING status. c. Not a fragment bundle.- Parameters:
bundle
-- Returns:
-
canStop
public static boolean canStop(org.osgi.framework.Bundle bundle) If the bundle fulfills the conditions below, it could be stopped a. Not in the UNINSTALLED status. b. Not in the STOPPING status. c. Not a fragment bundle.- Parameters:
bundle

canUninstall
public static boolean canUninstall(org.osgi.framework.Bundle bundle) If the bundle fulfills the conditions below, it could be un-installed a. Not in the UNINSTALLED status.- Parameters:
bundle
-- Returns:
-
isFragment
public static boolean isFragment(org.osgi.framework.Bundle bundle) -
getContextBundle
public static org.osgi.framework.Bundle getContextBundle(boolean unwrap) Returns bundle (if any) associated with current thread's context classloader. Invoking this method is equivalent to getBundle(Thread.currentThread().getContextClassLoader(), unwrap) -
getBundle
Returns bundle (if any) associated with the classloader.- Parameters:
classLoader
-unwrap
- if true and if the bundle associated with the context classloader is aDelegatingBundle
, this function will return the main application bundle backing theDelegatingBundle
. Otherwise, the bundle associated with the context classloader is returned as is. SeeBundleClassLoader.getBundle(boolean)
for more information.- Returns:
- The bundle associated with the classloader. Might be null.
-
unwrapBundle
public static org.osgi.framework.Bundle unwrapBundle(org.osgi.framework.Bundle bundle) If the given bundle is aDelegatingBundle
this function will return the main application bundle backing theDelegatingBundle
. Otherwise, the bundle passed in is returned as is. -

but also returns paths in attached fragment bundles.- Parameters:
bundle
-name
-- Returns:
-
getEntry
public static URL getEntry(org.osgi.framework.Bundle bundle, String name) throws MalformedURLException 1, If the bundle was installed with reference directory mode return the file URL directly. 2, For traditional package bundle, Works likeBundle.getEntry(String)

- Throws:
MalformedURLException

-
toFile
-
toFile
Translate the reference:file:// style URL to the underlying file instance- Parameters:
url
