32 | /** | |
33 | * Terribly simple tool to translate URIs into Turbine Links. | |
34 | * Equivalent to URIUtils.getAbsoluteLink() in a pull tool. | |
35 | * | |
36 | * <p> | |
37 | * If you're missing any routines from the 'old' $content tool concerning | |
38 | * path_info or query data, you did use the wrong tool then. You should've used | |
39 | * the TemplateLink tool which should be available as "$link" in your context. | |
40 | * <p> | |
41 | * | |
42 | * This is an application pull tool for the template system. You should <b>not</b> | |
43 | * use it in a normal application! | |
