public interface JspIdConsumer
This interface indicates to the container that a tag handler wishes to be provided with a compiler generated ID.
The container sets the jspId
attribute
of the tag handler with an identification string, as part of tag
property initialization. Each tag in a JSP page has a unique
jspId, and a given tag in a JSP page always has the same
jspId,
even for multiple requests to the page.
Tag handler instances that implement JspIdConsumer
cannot be reused.
Even though the jspId attribute is similar in concept to
the jsp:id
attribute of an XML view (see Section JSP.10.1.13 of the spec), they are
not related.
The jsp:id attribute is available only at translation time,
and the jspId
attribute is avalable only at request time.
The JSP container must provide a value for jspId that
conforms to the following rules:
Character.isLetter()
method) or underscore ('_').
Character.isLetter()
method), digits (as defined by the Character.isDigit() method), dashes ('-'),
or underscores ('_')
Note that the rules exclude colons ':' in a jspId,
and that they are
the same rules used for a component ID in JavaServer Faces.
