Examples of org.stringtemplate.v4.STGroupDir

org.stringtemplate.v4.STGroupFile
A directory or directory tree full of templates and/or group files. We load files on-demand. Dir search path: current working dir then CLASSPATH (as a resource). Do not look for templates outside of this dir subtree (except via imports).


  @Test public void testSubdirWithSubtemplate() throws Exception {
