Method Detail

doStartTag

public int doStartTag(String namespaceURI,
                      String localName,
                      String qName,
                      Attributes atts)
               throws SAXException

Description copied from class: TagSupport

Process the start tag for this instance.

The doStartTag method assumes that pageContext and parent have been set. It also assumes that any properties exposed as attributes have been set too. When this method is invoked, the body has not yet been evaluated.

Specified by:

doStartTag in interface Tag

Overrides:

doStartTag in class TagSupport

Returns:

EVAL_BODY or SKIP_BODY.

Throws:

SAXException

doAfterBody

public int doAfterBody()
                throws SAXException

Description copied from interface: IterationTag

Process body (re)evaluation. This method is invoked by the Taglib implementation object after every evaluation of the body into the BodyEvaluation object. The method is not invoked if there is no body evaluation.

If doAfterBody returns EVAL_BODY_AGAIN, a new evaluation of the body will happen (followed by another invocation of doAfterBody). If doAfterBody returns SKIP_BODY no more body evaluations will occur and then doEndTag will be invoked.

The method re-invocations may be lead to different actions because there might have been some changes to shared state, or because of external computation.

Specified by:

doAfterBody in interface IterationTag

Returns:

whether additional evaluations of the body are desired

Throws:

SAXException

setCount

public void setCount(String count)

recycle

public void recycle()

Specified by:

recycle in interface Recyclable

Overrides:

recycle in class TagSupport
