BodyTag, IterationTag, ParamHandler, Serializable, Tag

public class TreeFileTag

extends UrlTag

Like IncludeTag, but an entire tree of files is being probed to find the one that has the most specified value. This is a taglib-implementation of the 'TREEFILE' command. A full description of this command can be found in the mmbase-taglib.xml file.

doMakeRelative

protected boolean doMakeRelative()

Description copied from class: UrlTag

Whether URL must be generatored relatively. This default to false, and can be configured with the servlet context init parameter 'mmbase.taglib.url.makerelative'. It can be useful to be sure that url's are relative, if e.g. the context path is taken away in an URL-rewrite (e.g. by proxy). This might give problems with redirects, but if you happen to solve that too, or don't do that...

Overrides:

doMakeRelative in class UrlTag

getUrl

protected String getUrl(boolean writeamp,
                        boolean encode)
                 throws JspTagException

Description copied from class: UrlTag

Returns url with the extra parameters (of referids and sub-param-tags).

Overrides:

getUrl in class UrlTag

Throws:

JspTagException
