If this pointer manages a transparent container, like a variable, this method returns the pointer to the contents.

Usage

From source file:org.eclipse.e4.emf.internal.xpath.CollectionNodeIterator.java

/**
 * Prepare.../*ww w  . ja  va  2 s . co  m*/
 */
private void prepare() {
    collection = new ArrayList<>();
    NodePointer ptr = (NodePointer) pointer.clone();
    int length = ptr.getLength();
    for (int i = 0; i < length; i++) {
        ptr.setIndex(i);
        NodePointer elementPointer = ptr.getValuePointer();
        NodeIterator iter = getElementNodeIterator(elementPointer);

        for (int j = 1; iter.setPosition(j); j++) {
            NodePointer childPointer = iter.getNodePointer();
            if (reverse) {
                collection.add(0, childPointer);
            } else {
                collection.add(childPointer);
            }
        }
    }
    if (startWith != null) {
        int index = collection.indexOf(startWith);
        if (index == -1) {
            throw new JXPathException("Invalid starting pointer for iterator: " + startWith);
        }
        while (collection.size() > index) {
            if (!reverse) {
                collection.remove(collection.size() - 1);
            } else {
                collection.remove(0);
            }
