java.lang.Object
  org.springframework.web.servlet.tags.form.TagIdGenerator

final class TagIdGenerator
extends Object

Utility class for generating 'id' attributes values for JSP tags. Given the name of a tag (the data bound path in most cases) returns a unique ID for that name within the current PageContext. Each request for an ID for a given name will append an ever increasing counter to the name itself. For instance, given the name 'person.name', the first request will give 'person.name1' and the second will give 'person.name1'. This supports the common use case where a set of radio or check buttons are generated for the same data field, with each button being a distinct tag instance.
