public class NestedIterateTag

extends IterateTag

implements NestedNameSupport

NestedIterateTag. Slightly more complex that the other extensions. This one has to yield a proper index property. Very taxing.

Method Detail

doStartTag

public int doStartTag()
               throws javax.servlet.jsp.JspException

Overriding method of the heart of the matter. Gets the relative property and leaves the rest up to the original tag implementation. Sweet.

Overrides:

doStartTag in class IterateTag

Returns:

int JSP continuation directive. This is in the hands of the super class.

Throws:

javax.servlet.jsp.JspException - if a JSP exception has occurred

deriveNestedProperty

private java.lang.String deriveNestedProperty()

The only added property to the class. For use in proper nesting.

Returns:

String value of the property and the current index or mapping.

doAfterBody

public int doAfterBody()
                throws javax.servlet.jsp.JspException

This is only overriden as the include reference will need it's index updated.

Specified by:

doAfterBody in interface javax.servlet.jsp.tagext.BodyTag

Overrides:

doAfterBody in class IterateTag

Returns:

int JSP continuation directive.

Throws:

javax.servlet.jsp.JspException - if a JSP exception has occurred

doEndTag

public int doEndTag()
             throws javax.servlet.jsp.JspException

Complete the processing of the tag. The nested tags here will restore all the original value for the tag itself and the nesting context.

Specified by:

doEndTag in interface javax.servlet.jsp.tagext.Tag

Overrides:

doEndTag in class IterateTag

Returns:

int to describe the next step for the JSP processor

Throws:

javax.servlet.jsp.JspException - for the bad things JSP's do

release

public void release()

Release the tag's resources and reset the values.

Specified by:

Overrides:

release in class IterateTag
