Class ModuleContextLoader

java.lang.Object
  org.springframework.web.context.ContextLoader
      ch.elca.el4j.web.context.ModuleContextLoader

public class ModuleContextLoader
extends ContextLoader

This class extends Spring's ContextLoader. It inherits its complete behaviour but replaces the web application context with a ModuleWebApplicationContext which can be configured with inclusive configuration locations, exclusive configuration locations, and booleans indicating whether bean overriding is allowed and whether the resources retrieved by the configuration files section of the manifest files should be merged with resources found by searching in the file system.
