public class TrinidadBodyTagSupport extends TrinidadTagSupport implements javax.servlet.jsp.tagext.BodyTag
This is the Trinidad version of the JSP BodyTagSupport
class.
The main difference is that this class is NOT implementing the
Serializable
interface.
A base class for defining tag handlers implementing BodyTag.
The TrinidadBodyTagSupport class implements the BodyTag interface and adds additional convenience methods including getter methods for the bodyContent property and methods to get at the previous out JspWriter.
Many (Trinidad) tag handlers will extend TrinidadBodyTagSupport and only redefine a few methods.
