Class WikiEngine

  • All Implemented Interfaces:
    Engine
    public class WikiEngine
extends java.lang.Object
implements Engine
    Main implementation for Engine.

    Using this class: Always get yourself an instance from JSP page by using the WikiEngine.getInstance(..) method. Never create a new WikiEngine() from scratch, unless you're writing tests.

    • Field Detail

      • managers

        protected final java.util.Map<java.lang.Class<?>,​java.lang.Object> managers
        Stores WikiEngine's associated managers.

    • Constructor Detail

      • WikiEngine

        public WikiEngine​(java.util.Properties properties)
           throws WikiException
        Instantiate the WikiEngine using a given set of properties. Use this constructor for testing purposes only.
        Parameters:
        properties - A set of properties to use to initialize this WikiEngine.
        Throws:
        WikiException - If the initialization fails.

      • WikiEngine

        protected WikiEngine​(javax.servlet.ServletContext context,
                     java.lang.String appid,
                     java.util.Properties props)
              throws WikiException
        Instantiate using this method when you're running as a servlet and WikiEngine will figure out where to look for the property file. Do not use this method - use WikiEngine.getInstance() instead.
        Parameters:
        context - A ServletContext.
        appid - An Application ID. This application is a unique random string which is used to recognize this WikiEngine.
        props - The WikiEngine configuration.
        Throws:
        WikiException - If the WikiEngine construction fails.

    • Method Detail

      • getInstance

        public static WikiEngine getInstance​(javax.servlet.ServletConfig config)
                              throws InternalWikiException
        Gets a WikiEngine related to this servlet. Since this method is only called from JSP pages (and JspInit()) to be specific, we throw a RuntimeException if things don't work.
        Parameters:
        config - The ServletConfig object for this servlet.
        Returns:
        A WikiEngine instance.
        Throws:
        InternalWikiException - in case something fails. This is a RuntimeException, so be prepared for it.

      • getInstance

        public static WikiEngine getInstance​(javax.servlet.ServletConfig config,
                                     java.util.Properties props)
        Gets a WikiEngine related to the servlet. Works like getInstance(ServletConfig), but does not force the Properties object. This method is just an optional way of initializing a WikiEngine for embedded JSPWiki applications; normally, you should use getInstance(ServletConfig).
        Parameters:
        config - The ServletConfig of the webapp servlet/JSP calling this method.
        props - A set of properties, or null, if we are to load JSPWiki's default jspwiki.properties (this is the usual case).
        Returns:
        One well-behaving WikiEngine instance.

      • getInstance

        public static WikiEngine getInstance​(javax.servlet.ServletContext context,
                                     java.util.Properties props)
                              throws InternalWikiException
        Gets a WikiEngine related to the servlet. Works just like getInstance( ServletConfig )
        Parameters:
        context - The ServletContext of the webapp servlet/JSP calling this method.
        props - A set of properties, or null, if we are to load JSPWiki's default jspwiki.properties (this is the usual case).
        Returns:
        One fully functional, properly behaving WikiEngine.
        Throws:
        InternalWikiException - If the WikiEngine instantiation fails.
