org.jasig.portal.car.CarClassLoader
| CarClassLoader | | public class CarClassLoader extends SecureClassLoader (Code) | | Loads classes and resources from installed CARs via the CarResources class.
If classes are visible via the parent class loader then they will be used
in place of those in the CARs. This is a singleton so that we have a single
unified class namespace for all car resources preventing linkage errors and
class cast exceptions.

| Method Summary | |
| public Class | findClass(String name)
Implement the overloading of findClass to return classes that are
available from installed CAR files. | | public URL | findResource(String res)
Returns a URL pointing to a car resource if a suitable resource is
found in the loaded set of CAR files or null if one is not found. |
| CarClassLoader | | CarClassLoader()(Code) | | Create a CarClassLoader. This method has package scope so that
CarResources can instantiate it and hold the single instance to be
aquired via its getClassLoader() method.
|
| CarClassLoader | | CarClassLoader(ClassLoader cl)(Code) | | Create a CarClassloader with the indicated parent class loader. See
comment for zero parameter constructor for description of package scoping.
|
| findClass | | public Class findClass(String name) throws ClassNotFoundException(Code) | | Implement the overloading of findClass to return classes that are
available from installed CAR files. Class loading precedes with the
parent classloader first which delegates to this class loader if the
classes aren't found.
|
| findResource | | public URL findResource(String res)(Code) | | Returns a URL pointing to a car resource if a suitable resource is
found in the loaded set of CAR files or null if one is not found.
