java.lang.Objectcom.thoughtworks.xstream.io.path.PathTracker
public class PathTracker
Maintains the current Path
as a stream is moved through.
Can be linked to a HierarchicalStreamWriter
or
HierarchicalStreamReader
by wrapping them with a
PathTrackingWriter
or PathTrackingReader
.
PathTracker tracker = new PathTracker(); tracker.pushElement("table"); tracker.pushElement("tr"); tracker.pushElement("td"); tracker.pushElement("form"); tracker.popElement("form"); tracker.popElement("td"); tracker.pushElement("td"); tracker.pushElement("div"); Path path = tracker.getPath(); // returns "/table/tr/td[2]/div"

public PathTracker()

initialCapacity
- Size of the initial stack of nodes (one level per depth in the tree). Note that this is
only for optimizations - the stack will resize itself if it exceeds its capacity. If in doubt,
use the other constructor.Method Detail |
