Class ResourceController

java.lang.Object
  unbbayes.util.ResourceController

public class ResourceController
extends Object

This class is used to facilite the use of the diverses files of resources of the project. It contains methods to get this resources. Altered this class in order to use singleton pattern and make it possible to change the classloader/locales dinamically (e.g. plugins). If any classloader modification is needed, you may extend/implement a new ClassLoader and set it as this class' default classloader (as a example, you may implement a network classloader and set it as this singleton instance's default classloader). The plugin support is implemented by setting the default classloader as the plugin classloader.
