If the pointer represents a collection, the index identifies an element of that collection.

Usage

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

@Override
public int compareChildNodePointers(NodePointer pointer1, NodePointer pointer2) {
    return pointer1.getIndex() - pointer2.getIndex();
}
