    • preConfigure

      public void preConfigure(WebAppContext context) throws Exception
      Description copied from interface: Configuration
      Set up for configuration.

      Typically this step discovers configuration resources. Calls to preConfigure may alter the Configurations configured on the WebAppContext, so long as configurations prior to this configuration are not altered.

      Specified by:
      preConfigure in interface Configuration
      Overrides:
      preConfigure in class AbstractConfiguration
      Parameters:
      context - The context to configure
      Throws:
      Exception - if unable to pre configure

    • addDiscoverableAnnotationHandler

      public void addDiscoverableAnnotationHandler(AbstractDiscoverableAnnotationHandler handler)

    • configure

      public void configure(WebAppContext context) throws Exception
      Description copied from interface: Configuration
      Configure WebApp.

      Typically this step applies the discovered configuration resources to either the WebAppContext or the associated MetaData.

      Specified by:
      configure in interface Configuration
      Overrides:
      configure in class AbstractConfiguration
      Parameters:
      context - The context to configure
      Throws:
      Exception - if unable to configure

      Description copied from interface: Configuration
      Clear down after configuration.

      postConfigure in interface Configuration
      Overrides:
      postConfigure in class AbstractConfiguration
      Parameters:
      context - The context to configure
      Throws:
      Exception - if unable to post configure

    • scanForAnnotations

    • createAnnotationParser

      protected AnnotationParser createAnnotationParser(int javaPlatform)
      Parameters:
      javaPlatform - The java platform to scan for.
      Returns:
      a new AnnotationParser. This method can be overridden to use a different implementation of the AnnotationParser. Note that this is considered internal API.

    • isUseMultiThreading

      protected boolean isUseMultiThreading(WebAppContext context)
      Check if we should use multiple threads to scan for annotations or not
      Parameters:
      context - the context of the multi threaded setting
      Returns:
      true if multi threading is enabled on the context, server, or via a System property.

    • getMaxScanWait

      protected int getMaxScanWait(WebAppContext context)
      Work out how long we should wait for the async scanning to occur.
      Parameters:
      context - the context of the max scan wait setting
      Returns:
      the max scan wait setting on the context, or server, or via a System property.
