Class RuntimeJavaSourceLoader

java.lang.Object
  jodd.util.RuntimeJavaSourceLoader

public class RuntimeJavaSourceLoader
extends java.lang.Object

Manager for JavaSourceClassLoader: loading java sources transparently into the VM. When class is requested, it will be loaded using new instance of JavaSourceClassLoader. Non-aggressive mode is used, which means that only the request class is loaded with this classloader, all depended class are loaded with parent (default) classloader).

By default, RuntimeJavaSourceLoader monitors specified source folder for source file changes (using FileMonitor). If some source file is changed, class will be recompiled and reloaded and registered listener will be invoked.

Nested Class Summary

static interface

RuntimeJavaSourceLoader.ChangeListener Listener for class changes, invoked after the class reload.
