| Method Summary | |
| public static Set | clonePackageSet(Object toClone)
| | public static void | displayClassInfo(Class clazz, StringBuffer results)
Format a string buffer containing the Class, Interfaces, CodeSource,
and ClassLoader information for the given object clazz. | | public static URLClassLoader[] | getClassLoaderStack(ClassLoader cl)
| | public static URL[] | getClassLoaderURLs(ClassLoader cl)
Use reflection to access a URL[] getURLs or URL[] getClasspath method so
that non-URLClassLoader class loaders, or class loaders that override
getURLs to return null or empty, can provide the true classpath info. | | public static String | getJarClassName(String className)
| | public static String | getPackageName(String className)
Parse a class name into its package prefix. | | public static String | getResourceName(String className)
Parse a class name into its resource form. | | public static Set | newPackageSet()
| | public static String[] | updateClassNamesMap(RepositoryClassLoader cl, Map classNamesMap)
Given a UCL this method determine what classes it contains
and create a mapping from the class names to the cl. | | public static String[] | updateClassNamesMap(RepositoryClassLoader cl, Map classNamesMap, URL url, String[] prevClassNames)
Augment the class names associated with a UCL. | | static String[] | updateClassNamesMap(RepositoryClassLoader cl, Map classNamesMap, ClassPathIterator cpi, HashSet classNameSet)
| | public static String[] | updatePackageMap(RepositoryClassLoader cl, Map packagesMap)
Given a UCL this method determine what packages
it contains and create a mapping from the package names to the cl. | | public static String[] | updatePackageMap(RepositoryClassLoader cl, Map packagesMap, URL url, String[] prevPkgNames)
Augment the package name associated with a UCL. | | static String[] | updatePackageMap(RepositoryClassLoader cl, Map packagesMap, ClassPathIterator cpi, HashSet pkgNameSet)
|
| clonePackageSet | | public static Set clonePackageSet(Object toClone)(Code) | | Clone a package set
Parameters:
the - set to clone the cloned package set |
| displayClassInfo | | public static void displayClassInfo(Class clazz, StringBuffer results)(Code) | | Format a string buffer containing the Class, Interfaces, CodeSource,
and ClassLoader information for the given object clazz.
Parameters:
clazz - the Class
Parameters:
results - - the buffer to write the info to |
| getClassLoaderStack | | public static URLClassLoader[] getClassLoaderStack(ClassLoader cl)(Code) | | Get all of the URLClassLoaders from cl on up the hierarchy
Parameters:
cl - the class loader to start from The possibly empty array of URLClassLoaders from cl throughits parent class loaders |
| getClassLoaderURLs | | public static URL[] getClassLoaderURLs(ClassLoader cl)(Code) | | Use reflection to access a URL[] getURLs or URL[] getClasspath method so
that non-URLClassLoader class loaders, or class loaders that override
getURLs to return null or empty, can provide the true classpath info.
|
| getJarClassName | | public static String getJarClassName(String className)(Code) | | Translates a dot class name (java.lang.String) into a path form
suitable for a jar entry (java/lang/String.class)
Parameters:
className - java.lang.String java/lang/String.class |
| getPackageName | | public static String getPackageName(String className)(Code) | | Parse a class name into its package prefix. This has to handle
array classes whose name is prefixed with [L.
|
| getResourceName | | public static String getResourceName(String className)(Code) | | Parse a class name into its resource form. This has to handle
array classes whose name is prefixed with [L.
|
| newPackageSet | | public static Set newPackageSet()(Code) | | Create a new package set
the new package set |
| updateClassNamesMap | | public static String[] updateClassNamesMap(RepositoryClassLoader cl, Map classNamesMap) throws Exception(Code) | | Given a UCL this method determine what classes it contains
and create a mapping from the class names to the cl.
Parameters:
cl - the UCL that loads from url
Parameters:
