    Indicates if the class being initialized should be logged (default false).

• Constructor Detail

  • Initializer

    public Initializer(ClassLoader classLoader)

    Creates an initializer for the specified class loader.

• Method Detail

  • loadedClasses

    public Class<?>[] loadedClasses()

    Returns the classes loaded by the class loader of this initializer or null if not supported by the platform.

  • loadClass

    public void loadClass(Class<?> cls)

    Loads the specified class (does not perform any initialization). This method is typically used to load unreferenced classes.

  • initializeLoadedClasses

    public boolean initializeLoadedClasses()

    Initializes all the loaded classes. If the initialization leads to more classes being loaded, these classes are initialized as well (recursive process).

    Returns:

    true if initialization has been performed successfully; false otherwise.
