Java Utililty Methods XML Node Clone

N clone(final N node)
clone

return (N) node.cloneNode(true);

Node cloneNode(Node node)
Currently only use by GIFStreamMetadata and GIFImageMetadata

if (node == null) {
 return null;
IIOMetadataNode newNode = new IIOMetadataNode(node.getNodeName());
if (node instanceof IIOMetadataNode) {
 IIOMetadataNode iioNode = (IIOMetadataNode) node;
 Object obj = iioNode.getUserObject();
 if (obj instanceof byte[]) {
...

Node cloneNode(Node node, Document doc)
Clones the given DOM node into the given DOM document.

Node clone = null;
switch (node.getNodeType()) {
case Node.ELEMENT_NODE:
 clone = doc.createElement(node.getNodeName());
 NamedNodeMap attrs = node.getAttributes();
 for (int i = 0; i < attrs.getLength(); i++) {
 Node attrNode = attrs.item(i);
 Attr attrClone = doc.createAttribute(attrNode.getNodeName());
...

Node cloneNode(Node node, Document target, boolean deep)
Clone given Node into target Document.

if (target == null || node.getOwnerDocument() == target)
 return node.cloneNode(deep);
else {
 Node newNode;
 int nodeType = node.getNodeType();
 switch (nodeType) {
 case Node.ATTRIBUTE_NODE:
 newNode = target.createAttribute(node.getNodeName());

void copyGraphicFiles(String baseFilename, String currentDirectory, String fileSeparator, NodeIterator graphicsElements)
copy Graphic Files

byte[] buffer = new byte[4096];
int bytes_read;
while (currentNode != null) {
 FileInputStream fis = null;
 FileOutputStream fos = null;
 File fileToCopy = null;
 File copiedFile = null;
...

void copyInto(Node src, Node dest)
Copies the source tree into the specified place in a destination tree.

Document factory = dest.getOwnerDocument();
boolean domimpl = factory instanceof DocumentImpl;
Node start = src;
Node parent = src;
Node place = src;
while (place != null) {
 Node node = null;
 int type = place.getNodeType();
...

Document copyNode(Node source)
Copies node and all its children to the new document as root element in the new document

if (source == null) {
 return null;
Document sourceDoc = (source.getNodeType() == Node.DOCUMENT_NODE) ? (Document) source
 : source.getOwnerDocument();
Node rootNode = (source.getNodeType() == Node.DOCUMENT_NODE) ? sourceDoc.getDocumentElement() : source;
Preconditions.checkState(sourceDoc != null);
DOMImplementation domImpl = sourceDoc.getImplementation();
...

Node copyNode(Node source, Node dest)
Copy one node to another node.

if (source.getNodeType() == Node.TEXT_NODE) {
 Text tn = dest.getOwnerDocument().createTextNode(source.getNodeValue());
 return tn;
Node attr = null;
NamedNodeMap attrs = source.getAttributes();
if (attrs != null) {
 for (int i = 0; i < attrs.getLength(); i++) {
