The javax.servlet.jsp.tagext.BodyTag Interface
BodyTag extends Tag, adding extra callbacks and other methods allowing the developer to work with the
content of the tag.
A sequence diagram displays the interaction between calling JSP and tag handler in the case of a body tag; as
you can see, it is somewhat more complex than that of the Tag interface:
The extra steps involve the preservation of the JSP's JSPWriter (messages 5 and 10), and the possibility of
repeated calls to the doAfterBody() method, which enables the BodyTag implementation to take control
of the tag's execution at runtime.
