Method Detail

marshal

public void marshal(Object o,
                    com.thoughtworks.xstream.io.HierarchicalStreamWriter hierarchicalStreamWriter,
                    com.thoughtworks.xstream.converters.MarshallingContext marshallingContext)

Specified by:

marshal in interface com.thoughtworks.xstream.converters.Converter

unmarshal

public Object unmarshal(com.thoughtworks.xstream.io.HierarchicalStreamReader reader,
                        com.thoughtworks.xstream.converters.UnmarshallingContext context)
                 throws com.thoughtworks.xstream.converters.ConversionException

Specified by:

unmarshal in interface com.thoughtworks.xstream.converters.Converter

Parameters:

reader -

context -

Returns:

XstreamPathValueTracker

Throws:

com.thoughtworks.xstream.converters.ConversionException

readPath

protected void readPath(com.thoughtworks.xstream.io.path.PathTrackingReader reader,
                        com.thoughtworks.xstream.io.path.PathTracker tracker,
                        XstreamPathValueTracker pathValueTracker)

Reads through the tree looking for a specific path and returns the value at that node

The reader is moved to the next node in the path

For example, if readPath(reader, "a", "b", "c") is called, then the value at /a/b/c is returned and the reader is advanced to "" {code} <-- reader starts here value {code}

Parameters:

reader -

tracker -

pathValueTracker -

updatePath

protected void updatePath(com.thoughtworks.xstream.io.path.PathTrackingReader reader,
                          com.thoughtworks.xstream.io.path.Path path,
                          com.thoughtworks.xstream.io.path.Path currentPath,
                          XstreamPathValueTracker pathValueTracker)

doBasicPathsMatch

protected boolean doBasicPathsMatch(com.thoughtworks.xstream.io.path.Path pathObj1,
                                    com.thoughtworks.xstream.io.path.Path pathObj2)

This method uses a streaming-like approach to compare 2 paths with a single iteration. The comparison excludes count indexes in the path as well as the value of attributes in determining equivalence. For the purposes of this method, "/a/b/c" matches "/a/b[2]/c/@attr"

Parameters:

pathObj1 - The first path

pathObj2 - The second path

Returns:

If the paths match

canConvert

public boolean canConvert(Class clazz)
