public DefaultURLConstructor()

Method Detail

initialize

public void initialize(Engine engine,
                       java.util.Properties properties)

Specified by:

initialize in interface Initializable

doReplacement

protected final java.lang.String doReplacement(java.lang.String baseptrn,
                                               java.lang.String name)

Does replacement of some particular variables. The variables are:

• "%u" - inserts either the base URL (when absolute is required), or the base path (which is an absolute path without the host name).
• "%U" - always inserts the base URL
• "%p" - always inserts the base path
• "%n" - inserts the page name

Parameters:

baseptrn - The pattern to use

name - The page name

Returns:

A replacement.

getURLPattern

public static java.lang.String getURLPattern(java.lang.String context,
                                             java.lang.String name)
                                      throws java.lang.IllegalArgumentException

Returns the URL pattern for a supplied wiki request context.

Parameters:

context - the wiki context

name - the wiki page

Returns:

A pattern for replacement.

Throws:

java.lang.IllegalArgumentException - if the context cannot be found

makeURL

public java.lang.String makeURL(java.lang.String context,
                                java.lang.String name,
                                java.lang.String parameters)

Constructs the URL with a bunch of parameters.

Specified by:

makeURL in interface URLConstructor

Parameters:

parameters - If null or empty, no parameters are added. An URL parameter string (these must be URL-encoded, and separated with &)

context - The request context (@see WikiContext) that you want the URL for

name - The page name (or in case of WikiContext.NONE, the auxiliary JSP page or resource you want to point at). This must be URL encoded. Null is NOT safe.

Returns:

An URL pointing to the resource. Must never return null - throw an InternalWikiException if something goes wrong.

parsePage

public java.lang.String parsePage(java.lang.String context,
                                  javax.servlet.http.HttpServletRequest request,
                                  java.nio.charset.Charset encoding)

Should parse the "page" parameter from the actual request. Should parse the "page" parameter from the actual request. This is essentially the reverse of makeURL() - whenever a request constructed by calls to makeURL() is passed to this routine, it MUST be able to parse the resource name (WikiPage, Attachment, other resource) from the request.

Specified by:

parsePage in interface URLConstructor

Parameters:

context - In which request context the request was made (this should help in parsing)

request - The HTTP request that was used when coming here

encoding - The encoding with which the request was made (UTF-8 or ISO-8859-1).

Returns:

This method must return the name of the resource.

getForwardPage

public java.lang.String getForwardPage(javax.servlet.http.HttpServletRequest request)

This method is not needed for the DefaultURLConstructor.

Specified by:

getForwardPage in interface URLConstructor

Parameters:

request - The HTTP Request that was used to end up in this page.

Returns:

"Wiki.jsp", "PageInfo.jsp", etc. Just return the name, JSPWiki will figure out the page.
