```
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).

Method Summary

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`doEndTag()`	If `rendering`, flush any buffered `BodyContent` or, if no `BodyContent` is supplied, `render the default content`.
`void`	`doFinally()`	Clean up any attributes and stored resources.
`void`	`doInitBody()`
`protected void`	`exposeAttributes()`	Called during `writeTagContent(org.springframework.web.servlet.tags.form.TagWriter)` allowing subclasses to add any attributes to the `PageContext` as needed.
`protected void`	`flushBufferedBodyContent(BodyContent bodyContent)`	The user customised the output of the error messages - flush the buffered content into the main `JspWriter`.
`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.
`protected void`	`removeAttributes()`	Called by `doFinally()` allowing subclasses to remove any attributes from the `PageContext` as needed.
`protected abstract void`	`renderDefaultContent(TagWriter tagWriter)`
`protected void`	`renderFromBodyContent(BodyContent bodyContent, TagWriter tagWriter)`	Render the tag contents based on the supplied `BodyContent`.
`void`	`setBodyContent(BodyContent bodyContent)`
`protected boolean`	`shouldRender()`	Should rendering of this tag proceed at all.
`protected int`	`writeTagContent(TagWriter tagWriter)`	Subclasses should implement this method to perform tag content rendering.

```
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:
    a Tag.EVAL_PAGE result
    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
