        java.lang.String getPageText​(java.lang.String pageName,
                             int version)
                      throws ProviderException
        Fetches the page text from the repository. This method also does some sanity checks, like checking for the pageName validity, etc. Also, if the page repository has been modified externally, it is smart enough to handle such occurrences.
        Parameters:
        pageName - The name of the page to fetch.
        version - The version to find
        Returns:
        The page content as a raw string

        java.lang.String getPureText​(java.lang.String page,

        Returns the pure text of a page, no conversions. Use this if you are writing something that depends on the parsing of the page. Note that you should always check for page existence through pageExists() before attempting to fetch the page contents. This method is pretty similar to getPageText(String, int), except that it doesn't throw ProviderException, it logs and swallows them.
        Parameters:
        page - The name of the page to fetch.
        version - If WikiPageProvider.LATEST_VERSION, then uses the latest version.
        Returns:
        The page contents. If the page does not exist, returns an empty string.

        Returns the pure text of a page, no conversions. Use this if you are writing something that depends on the parsing the page. Note that you should always check for page existence through pageExists() before attempting to fetch the page contents. This method is pretty similar to getPageText(String, int), except that it doesn't throw ProviderException, it logs and swallows them.
        Parameters:
        page - A handle to the WikiPage
        Returns:

        The page content as HTMLized String.

              java.lang.String text)
       throws WikiException
        Writes the WikiText of a page into the page repository. If the jspwiki.properties file contains the property jspwiki.approver.workflow.saveWikiPage and its value resolves to a valid user, Group or Role, this method will place a Decision in the approver's workflow inbox and throw a DecisionRequiredException. If the submitting user is authenticated and the page save is rejected, a notification will be placed in the user's decision queue.
        Parameters:
        context - The current WikiContext
        text - The Wiki markup for the page.
