Examples of freemarker.template.Template.process()

freemarker.template.Template.process()
Processes the template, using data from the map, and outputs the resulting text to the supplied Writer The elements of the map are converted to template models using the default object wrapper returned by the {@link Configuration#getObjectWrapper() getObjectWrapper()}method of the Configuration. @param rootMap the root node of the data model. If null, anempty data model is used. Can be any object that the effective object wrapper can turn into a TemplateHashModel. Basically, simple and beans wrapper can turn java.util.Map objects into hashes and the Jython wrapper can turn both a PyDictionary as well as any object that implements __getitem__ into a template hash. Naturally, you can pass any object directly implementing TemplateHashModel as well. @param out a Writer to output the text to. @throws TemplateException if an exception occurs during template processing @throws IOException if an I/O exception occurs during writing to the writer.
