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 available 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.
