IfTag (Jakarta Standard Tag Library Implementation 3.0.1 API)

java.lang.Object
- jakarta.servlet.jsp.tagext.TagSupport
- - jakarta.servlet.jsp.jstl.core.ConditionalTagSupport
  - - org.apache.taglibs.standard.tag.el.core.IfTag

All Implemented Interfaces:

jakarta.servlet.jsp.tagext.IterationTag, jakarta.servlet.jsp.tagext.JspTag, jakarta.servlet.jsp.tagext.Tag, Serializable
```
public class IfTag
extends jakarta.servlet.jsp.jstl.core.ConditionalTagSupport
```
Tag handler for <if> in JSTL's expression-evaluating library. Because of the support provided by the ConditionalTagSupport class, thistag is trivial enough not to require a separate base supporting class common to both libraries.
