All Implemented Interfaces:

Serializable, BodyTag, IterationTag, JspTag, Tag
```
public class BodyTagSupport
extends TagSupport
implements BodyTag
```
A base class for defining tag handlers implementing BodyTag.
The BodyTagSupport class implements the BodyTag interface and adds additional convenience methods including getter methods for the bodyContent property and methods to get at the previous out JspWriter.
Many tag handlers will extend BodyTagSupport and only redefine a few methods.
