Examples of org.antlr.stringtemplate.StringTemplateGroup

org.antlr.stringtemplate.StringTemplateGroup
Manages a group of named mutually-referential StringTemplate objects. Currently the templates must all live under a directory so that you can reference them as foo.st or gutter/header.st. To refresh a group of templates, just create a new StringTemplateGroup and start pulling templates from there. Or, set the refresh interval. Use getInstanceOf(template-name) to get a string template to fill in. The name of a template is the file name minus ".st" ending if present unless you name it as you load it. You can use the group file format also to define a group of templates (this works better for code gen than for html page gen). You must give a Reader to the ctor for it to load the group; this is general and distinguishes it from the ctors for the old-style "load template files from the disk". 10/2005 I am adding a StringTemplateGroupLoader concept so people can define supergroups within a group and have it load that group automatically.
