  • Method Details

    • getProvider

      PageProvider getProvider()
      Returns the page provider currently in use.
      Returns:
      A WikiPageProvider instance.

    • getAllPages

      Collection<Page> getAllPages() throws ProviderException
      Returns all pages in some random order. If you need just the page names, please see ReferenceManager#findCreated(), which is probably a lot faster. This method may cause repository access.
      Returns:
      A Collection of WikiPage objects.
      Throws:
      ProviderException - If the backend has problems.

    • getPageText

      String getPageText​(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
      Throws:
      ProviderException - If the backend has issues.

    • getPureText

      String getPureText​(String page, int version)
      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.

    • getPureText

      default String getPureText​(Page page)
      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:
      String of WikiText.
      Since:
      2.1.13, moved to PageManager on 2.11.0.

    • getText

      String getText​(String page, int version)
      Returns the un-HTMLized text of the given version of a page. This method also replaces the < and & -characters with their respective HTML entities, thus making it suitable for inclusion on an HTML page. If you want to have the page text without any conversions, use getPureText(String, int).
      Parameters:
      page - WikiName of the page to fetch
      version - Version of the page to fetch
      Returns:
      WikiText.

      default String getText​(String page)
      Returns the un-HTMLized text of the latest version of a page. This method also replaces the < and & -characters with their respective HTML entities, thus making it suitable for inclusion on an HTML page. If you want to have the page text without any conversions, use getPureText(String, int).
      Parameters:
      page - WikiName of the page to fetch.
      Returns:
      WikiText.

    • getText

      default String getText​(Page page)
      Returns the un-HTMLized text of the given version of a page in the given context. USE THIS METHOD if you don't know what doing.

      This method also replaces the < and & -characters with their respective HTML entities, thus making it suitable for inclusion on an HTML page. If you want to have the page text without any conversions, use getPureText(Page).

      Parameters:
      page - A page reference (not an attachment)
      Returns:
      The page content as HTMLized String.
      Since:

    • saveText

      void saveText​(Context context, 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.
      Throws:
      WikiException - if the save operation encounters an error during the save operation. If the page-save operation requires approval, the exception will be of type DecisionRequiredException. Individual PageFilters, such as the SpamFilter may also throw a RedirectException.
      Since:
      2.1.28, moved to PageManager on 2.11.0

    • putPageText

      void putPageText​(Page page, String content) throws ProviderException

      page - Page to save
      content - Wikimarkup to save
      Throws:
      ProviderException - If something goes wrong in the saving phase
