getCodeBase

public String getCodeBase(Class<?> cls)

Description copied from interface: ClassCodeBaseHandler

Returns some sort of codebase for the given class, or null. It is expected that, if str is the result of getCodeBase( cls ), then loadClass( str, cls.getClassName() ) will return cls.

Specified by:

getCodeBase in interface ClassCodeBaseHandler

Parameters:

cls - Class for which we need a codebase

Returns:

A codebase to use with this handler, or null if this handler does not apply to this class.

couldNotLoadClassInBundle

@InfoMethod
private void couldNotLoadClassInBundle(ClassNotFoundException exc,
 String className,
 String bname)

foundClassInBundleVersion

@InfoMethod
private void foundClassInBundleVersion(String cname,
 String bname,
 String version)

classNotFoundInBundleVersion

@InfoMethod
private void classNotFoundInBundleVersion(String cname,
 String bname,
 String version)

loadClass

public Class<?> loadClass(String codebase,
 String className)

Description copied from interface: ClassCodeBaseHandler

load a class given the classname and a codebase. The className will always satisfy cls.getClassName().equals( className ) if the call succeeds and returns a Class.

Specified by:

loadClass in interface ClassCodeBaseHandler

Parameters:

codebase - A string that somehow describes which ClassLoader to use. For example, the string could be an ordinary URL that a URL ClassLoader can use, or something more specialized, such as a description of an OSGi bundles and version.

className - The name of the class to load

Returns:

The loaded class, or null if the class could not be loaded.
