Interface com.openly.dt.DynamicTag

public abstract interface DynamicTag

Think of DynamicTags as objects that make up intelligent blocks of a servlet page. The JSText Objects take care of passing Params objects to dynamic tags appearing on a template. All parameters should be passed to and from DynamicTags through Params objects. DynamicTag objects should be stateless, they should not be required to appear on a template in a certain order or should fail gracefully if they do.

Instead of creating a new DynamicTag for each bit of dynamic data, consider subclassing Params to make a special object that understand a particular set of tag names.

The philosophy behind the com.openly.dt package is to facilitate 100% clean separation of code from data in a servlet application. Templates invoke objects, and the servlet function should be restricted to initializing a Params object selecting the appropriate template
