decreaseRecursionDepthLoop

Use

Repeatedly includes its body as many times as the recursion depth decreases, if the next node is on a higher level or if the overall recursion ends. This tag can be used to close HTML tags on the way back up in a nested tree structure.

Name	Mandatory	Description
currentIndex	No	The name of a Java variable that holds the Byte object for the current loop index. The variable can be accessed in scriptlets in the body of the tag.

Name	Scope	Description
currentIndex attribute	Tag body	A Byte object representing the current loop index

Cooperating Tags

The tag must be nested in the ifNextRecursionDepthWillDecrease

tag.

Example

The following code displays a site map of all navigation nodes using the nested unordered lists for markup. The ifNextRecursionDepthWillDecrease tag closes the <li> tag belonging to the current node, and the <ul> and <li> tag of the current level and upper levels as many times as necessary, since either the next recursion pass continues with a sibling of the current node's ancestor node or the recursion ends after this node.

            <ul>
<nav:iterateInitialNavNodes>
    <nav:recurseNavNodeChildren>
    <li>        
        <nav:navNodeAnchor navigationMethod="byURL"/>

        <nav:ifNextRecursionDepthWillNotChange>
            </li>
        </nav:ifNextRecursionDepthWillNotChange>

        <nav:ifNextRecursionDepthWillIncrease>
            <ul>
        </nav:ifNextRecursionDepthWillIncrease>

        <nav:ifNextRecursionDepthWillDecrease>
            </li>
            <nav:decreaseRecursionDepthLoop>
                </ul></li>
            </nav:decreaseRecursionDepthLoop>
        </nav:ifNextRecursionDepthWillDecrease>
    </nav:recurseNavNodeChildren>
</nav:iterateInitialNavNodes>
</ul>
