public abstract class AbstractHtmlElementBodyTag
- extends AbstractHtmlElementTag
- implements BodyTag
Convenient super class for many html tags that render content using the databinding
features of the AbstractHtmlElementTag. The only thing sub tags
need to do is override renderDefaultContent(TagWriter).

AbstractHtmlElementBodyTag
public AbstractHtmlElementBodyTag()
writeTagContent
protected int writeTagContent(TagWriter tagWriter)
throws JspException
- Description copied from class:
AbstractFormTag
- Subclasses should implement this method to perform tag content rendering.
- Specified by:
writeTagContent in class AbstractFormTag
- Returns:
- valid tag render instruction as per
Tag.doStartTag().
- Throws:
JspException
doEndTag
public int doEndTag()
throws JspException
- If
rendering, flush any buffered
BodyContent or, if no BodyContent is supplied,
render the default content.
- Specified by:
doEndTag in interface Tag- Overrides:
doEndTag in class TagSupport
- Returns:
- Tag#EVAL_PAGE
- Throws:
JspException
renderFromBodyContent
protected void renderFromBodyContent(BodyContent bodyContent,
TagWriter tagWriter)
throws JspException
- Render the tag contents based on the supplied
BodyContent.
The default implementation simply flushes
the BodyContent directly to the output. Subclasses may choose to
override this to add additional content to the output.
- Throws:
JspException
doFinally
public void doFinally()
- Clean up any attributes and stored resources.
- Specified by:
doFinally in interface TryCatchFinally- Overrides:
doFinally in class AbstractDataBoundFormElementTag
onWriteTagContent
protected void onWriteTagContent()
- Called at the start of
writeTagContent(org.springframework.web.servlet.tags.form.TagWriter) allowing subclasses to perform
any precondition checks or setup tasks that might be necessary.
shouldRender
protected boolean shouldRender()
throws JspException
- Should rendering of this tag proceed at all. Returns '
true' by default
causing rendering to occur always, Subclasses can override this if they
provide conditional rendering.
- Throws:
JspException
exposeAttributes
protected void exposeAttributes()
throws JspException
- Called during
writeTagContent(org.springframework.web.servlet.tags.form.TagWriter) allowing subclasses to add any attributes to the
PageContext as needed.
- Throws:
JspException
removeAttributes
protected void removeAttributes()
- Called by
doFinally() allowing subclasses to remove any attributes from the
PageContext as needed.
flushBufferedBodyContent
protected void flushBufferedBodyContent(BodyContent bodyContent)
throws JspException
- The user customised the output of the error messages - flush the
buffered content into the main
JspWriter.
- Throws:
JspException
renderDefaultContent
protected abstract void renderDefaultContent(TagWriter tagWriter)
throws JspException
- Throws:
JspException
doInitBody
public void doInitBody()
throws JspException
- Specified by:
doInitBody in interface BodyTag
- Throws:
JspException
setBodyContent
public void setBodyContent(BodyContent bodyContent)
- Specified by:
setBodyContent in interface BodyTag
