java.lang.Objectjavax.servlet.jsp.tagext.TagLibraryValidator
Translation-time validator class for a JSP page. A validator operates on the XML document associated with the JSP page.
The TLD file associates a TagLibraryValidator class and some init arguments with a tag library.
The JSP container is reponsible for locating an appropriate instance of the appropriate subclass by
A TagLibraryValidator instance may create auxiliary objects internally to perform the validation (e.g. an XSchema validator) and may reuse it for all the pages in a given translation run.
The JSP container is not guaranteed to serialize invocations of validate() method, and TagLibraryValidators should perform any synchronization they may require.
A JSP container may optionally support a jsp:id attribute to provide higher quality validation errors. When supported, the container will track the JSP pages as passed to the container, and will assign to each element a unique "id", which is passed as the value of the jsp:id attribute. Each XML element in the XML view available will be extended with this attribute. The TagLibraryValidator can then use the attribute in one or more ValidationMessage objects. The container then, in turn, can use these values to provide more precise information on the location of an error.
