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.

Constructor Detail

### NestedIterateTag

    public NestedIterateTag()

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.

  Specified by:
    `doStartTag` in interface `javax.servlet.jsp.tagext.Tag`
  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:
    `release` in interface `javax.servlet.jsp.tagext.Tag`
  Overrides:
    `release` in class `IterateTag`
