Actually instance interpolate() is the most important method. Each synthetic StringTemplate gets a specialized interpolate providing performance equivalent to string concat. And, a good percentage  of processors will work with the result of interpolate to produce result. Ex. `StringProcessor STR = st -> st.interpolate();` and`TemplateProcessor<JSONObject> JSON = st -> new JSONObject(st.interpolate());`
