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.
