Property Getters/Setters Detail

• getCustomNodeId/setCustomNodeId

  public int getCustomNodeId() / public void setCustomNodeId(int value)
  

  Specifies custom node identifier.

  Default is zero.

  This identifier can be set and used arbitrarily. For example, as a key to get external data.

  Important note, specified value is not saved to an output file and exists only during the node lifetime.

  Example:

  Shows how to traverse through a composite node's collection of child nodes.

  Document doc = new Document();
  
  // Add two runs and one shape as child nodes to the first paragraph of this document.
  Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
  paragraph.appendChild(new Run(doc, "Hello world! "));
  
  Shape shape = new Shape(doc, ShapeType.RECTANGLE);
  shape.setWidth(200.0);
  shape.setHeight(200.0);
  // Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
  shape.setCustomNodeId(100);
  shape.setWrapType(WrapType.INLINE);
  paragraph.appendChild(shape);
  
  paragraph.appendChild(new Run(doc, "Hello again!"));
  
  // Iterate through the paragraph's collection of immediate children,
  // and print any runs or shapes that we find within.
  NodeCollection children = paragraph.getChildNodes();
  
  Assert.assertEquals(3, paragraph.getChildNodes().getCount());
  
  for (Node child : (Iterable<Node>) children)
      switch (child.getNodeType()) {
          case NodeType.RUN:
              System.out.println("Run contents:");
              System.out.println("\t\"{child.GetText().Trim()}\"");
              break;
          case NodeType.SHAPE:
              Shape childShape = (Shape) child;
              System.out.println("Shape:");
              System.out.println("\t{childShape.ShapeType}, {childShape.Width}x{childShape.Height}");
              break;
      }

• getDocument

  public DocumentBase getDocument()
  

  Gets the document to which this node belongs.

  The node always belongs to a document even if it has just been created and not yet added to the tree, or if it has been removed from the tree.

  Example:

  Shows how to create a node and set its owning document.

  Document doc = new Document();
  Paragraph para = new Paragraph(doc);
  para.appendChild(new Run(doc, "Hello world!"));
  
  // We have not yet appended this paragraph as a child to any composite node.
  Assert.assertNull(para.getParentNode());
  
  // If a node is an appropriate child node type of another composite node,
  // we can attach it as a child only if both nodes have the same owner document.
  // The owner document is the document we passed to the node's constructor.
  // We have not attached this paragraph to the document, so the document does not contain its text.
  Assert.assertEquals(para.getDocument(), doc);
  Assert.assertEquals("", doc.getText().trim());
  
  // Since the document owns this paragraph, we can apply one of its styles to the paragraph's contents.
  para.getParagraphFormat().setStyleName("Heading 1");
  
  // Add this node to the document, and then verify its contents.
  doc.getFirstSection().getBody().appendChild(para);
  
  Assert.assertEquals(doc.getFirstSection().getBody(), para.getParentNode());
  Assert.assertEquals("Hello world!", doc.getText().trim());

• isComposite

  public boolean isComposite()
  

  Returns true if this node can contain other nodes.

  This method returns false as Node cannot have child nodes.

  Example:

  Shows how to traverse a composite node's tree of child nodes.

  public void recurseChildren() throws Exception {
      Document doc = new Document(getMyDir() + "Paragraphs.docx");
  
      // Any node that can contain child nodes, such as the document itself, is composite.
      Assert.assertTrue(doc.isComposite());
  
      // Invoke the recursive function that will go through and print all the child nodes of a composite node.
      traverseAllNodes(doc, 0);
  }
  
  /// <summary>
  /// Recursively traverses a node tree while printing the type of each node
  /// with an indent depending on depth as well as the contents of all inline nodes.
  /// </summary>
  @Test(enabled = false)
  public void traverseAllNodes(CompositeNode parentNode, int depth) {
      for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling()) {
          System.out.println(MessageFormat.format("{0}{1}", String.format("    ", depth), Node.nodeTypeToString(childNode.getNodeType())));
  
          // Recurse into the node if it is a composite node. Otherwise, print its contents if it is an inline node.
          if (childNode.isComposite()) {
              System.out.println();
              traverseAllNodes((CompositeNode) childNode, depth + 1);
          } else if (childNode instanceof Inline) {
              System.out.println(" - \"{childNode.GetText().Trim()}\"");

• deepClone

  public Node deepClone(boolean isCloneChildren)

  Creates a duplicate of the node.

  This method serves as a copy constructor for nodes. The cloned node has no parent, but belongs to the same document as the original node.

  Parameters:

  isCloneChildren - True to recursively clone the subtree under the specified node; false to clone only the node itself.

  Returns:

  The cloned node.

  Example:

  Shows how to clone a composite node.

  // and end up with a document node with no children.

  // If we wish to edit it, we will need to repopulate its node collection.
  // First, create a new section, and then append it as a child to the root document node.

      }

  Example:

  Exports the content of a node to String in HTML format.

  Document doc = new Document(getMyDir() + "Document.docx");
  
  Node node = doc.getLastSection().getBody().getLastParagraph();
  
  // When we call the ToString method using the html SaveFormat overload,
