| 28 | * Default implementation of TemplateLoaderFactory interface. | |
| 29 | * This implementation expects config strings to be in an url-like | |
| 30 | * format: [protocol:][path]. It will then look for a key in the | |
| 31 | * WebMacro configuration of the form "TemplateLoader.<protocol>", where | |
| 32 | * protocol is replaced by "default", if it is ommited in the url. The | |
| 33 | * value of this configuration option has to be a fully qualified class | |
| 34 | * name of a class with a no-args constructor, implementing the TemplateLoader | |
| 35 | * interface. | |
| 36 | * <br> | |
| 37 | * After instantiating an object of this class, "path" is passed as configuration | |
| 38 | * option to this object. | |
