Examples of org.stringtemplate.v4.ST

org.stringtemplate.v4.ST
An instance of the StringTemplate. It consists primarily of a reference to its implementation (shared among all instances) and a hash table of attributes. Because of dynamic scoping, we also need a reference to any enclosing instance. For example, in a deeply nested template for an HTML page body, we could still reference the title attribute defined in the outermost page template. To use templates, you create one (usually via STGroup) and then inject attributes using add(). To render its attacks, use render().
