Examples of NullElementPointer

org.apache.commons.jxpath.ri.model.beans.NullElementPointer
Used when there is a need to construct a Pointer for a collection element that does not exist. For example, if the path is "foo[3]", but the collection "foo" only has one element or is empty or is null, the NullElementPointer can be used to capture this situation without putting a regular NodePointer into an invalid state. Just create a NullElementPointer with index 2 (= 3 - 1) and a "foo" pointer as the parent. @author Dmitri Plotnikov @version $Revision: 1.14 $ $Date: 2003/03/11 00:59:25 $
