Examples of MLet

javax.management.loading.MLet
URL classloader capable of parsing an MLet text file adhering to the file format defined in the JMX specification (v1.0). @see javax.management.loading.MLetMBean @author Juha Lindfors. @version $Revision: 1.13 $
Revisions:
20020313 Juha Lindfors:
- Added MLet text file ARG tag support
20020317 Juha Lindfors:
- Unified Loader Repository support
- We need to intercept addURL() call since MLet CL exposes this as a public method (unlike URL CL). This means the set of URLs in this classloaders scope may change after it has been registered to the repository.
- We override loadClass() to delegate class loading directly to the repository in case a Unified Loader Repository is installed. This means in case of ULR this classloader is never used to load classes. The ULR has a set of Unified CLs that match the URLs added to this CL.
20020501 Fusayuki Minamoto:
- Added MLet text file VERSION tag support
20020811 Adrian Brock:
- Fix the Unified Repository Support to be more spec compliant.
