I want to know when the method "public void setName" is invoked?

Question

The jsp file contain the one which list below:
<mt:hello name="foo"/>
package com.acme.tag;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class HelloTag extends TagSupport
private String name="";
public HelloTag()
super();
� public void setName(String name) �
� {                                                                    �
� this.name=name; �
� } �
�_____________________________________________�
public int doEndTag() throws javax.servlet.jsp.JspTagException
try
pageContext.getOut().write("Hello "+name+"!");
catch(java.io.IOException e)
throw new JspTagException("IO Error: " + e.getMessage());
return EVAL_PAGE;
}

Answer 1

does the other method like :
<b>public void setPageContext(PageContext PageContext)</b>
and
<b>public javax.servlet.jsp.tagext.Tag getParent()</b>
is invoked like setName list above.
Thanks!
