com.acciente.commons.loader.ReloadingClassLoader

This classloader loads classes retrieved via a class definition loader (aka ClassDefLoader). This class loader uses the methods provided by a ClassDef (a ClassDef is returned by the ClassDefLoader) to determine if the class has been modified and transparently reloads the class into the JVM if the ClassDef reports that the class has been modified.

This class loader also reads dependency information from the ClassDef. When the load of a class, say A, is requested it recursively checks for modificiations to dependent classes. If any of the the dependent classes are modified it first reloads the dependent classes and then proceeds to reload the class A. @see ClassDefLoader @see ClassDef @created Feb 23, 2008 @change-summary Feb 27, 2008 APR refactored SourceClassLoader -> ReloadingClassLoader @change-summary May 21, 2008 APR refactored to support a list of ClassDefLoaders to enablesearching in multiple load locations without the need to to chain classloaders. @author Adinath Raveendra Raj
