Class BookmarkStart

java.lang.Object
  extended by Node
      extended by com.aspose.words.BookmarkStart
All Implemented Interfaces:
java.lang.Cloneable, java.lang.Iterable

public class BookmarkStart 
extends Node

Represents a start of a bookmark in a Word document.

A complete bookmark in a Word document consists of a BookmarkStart and a matching BookmarkEnd with the same bookmark name.

BookmarkStart and BookmarkEnd are just markers inside a document that specify where the bookmark starts and ends.

Use the Bookmark class as a "facade" to work with a bookmark as a single object.

Note: Currently bookmarks are supported only at the inline-level, that is inside Paragraph, but bookmark start and bookmark end can be in different paragraphs.

Constructor Detail

BookmarkStart

public BookmarkStart(Document doc, java.lang.String name)
Initializes a new instance of the BookmarkStart class.
Parameters:
doc - The owner document.
name - The name of the bookmark. Cannot be null.

Property Getters/Setters Detail

getNodeType

public int getNodeType()
Returns NodeType.BOOKMARK_START. The value of the property is NodeType integer constant.

getName

public java.lang.String getName()
Get the bookmark name.

Cannot be null.


getBookmark

public Bookmark getBookmark()
Gets the facade object that encapsulates this bookmark start and end.

getParentNode

→ inherited from Node
public CompositeNode getParentNode()
Gets the immediate parent of this node.

If a node has just been created and not yet added to the tree, or if it has been removed from the tree, the parent is null.

Example:

Shows how to access the parent node.
// Create a new empty document. It has one section.
Document doc = new Document();

// The section is the first child node of the document.
Node section = doc.getFirstChild();

// The section's parent node is the document.
Assert.assertEquals(doc, section.getParentNode());

Example:

Shows that when you create any node, it requires a document that will own the node.
// Open a file from disk.
Document doc = new Document();

// Creating a new node of any type requires a document passed into the constructor.
Paragraph para = new Paragraph(doc);

// The new paragraph node does not yet have a parent.
Assert.assertNull(para.getParentNode());

// But the paragraph node knows its document.
Assert.assertEquals(doc, para.getDocument());

// The fact that a node always belongs to a document allows us to access and modify
// properties that reference the document-wide data such as styles or lists.
para.getParagraphFormat().setStyleName("Heading 1");

// Now add the paragaph to the main text of the first section.
doc.getFirstSection().getBody().appendChild(para);

// The paragraph node is now a child of the Body node.
Assert.assertNotNull(para.getParentNode());

getDocument

→ inherited from Node
public Document 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 yed added to the tree, or if it has been removed from the tree.

Example:

Shows that when you create any node, it requires a document that will own the node.
// Open a file from disk.
Document doc = new Document();

// Creating a new node of any type requires a document passed into the constructor.
Paragraph para = new Paragraph(doc);

// The new paragraph node does not yet have a parent.
Assert.assertNull(para.getParentNode());

// But the paragraph node knows its document.
Assert.assertEquals(doc, para.getDocument());

// The fact that a node always belongs to a document allows us to access and modify
// properties that reference the document-wide data such as styles or lists.
para.getParagraphFormat().setStyleName("Heading 1");

// Now add the paragaph to the main text of the first section.
doc.getFirstSection().getBody().appendChild(para);

// The paragraph node is now a child of the Body node.
Assert.assertNotNull(para.getParentNode());

getPreviousSibling

→ inherited from Node
public Node getPreviousSibling()
Gets the node immediately preceding this node.

If there is no preceding node, a null is returned.

Note: Calculating the value of this property iterates from the first child node of ParenNode to this node.

Example:

Demonstrates use of methods of Node and CompositeNode to remove a section before the last section in the document.
// Document is a CompositeNode and LastChild returns the last child node in the Document node.
// Since the Document can contain only Section nodes, the last child is the last section.
Node lastSection = doc.getLastChild();

// Each node knows its next and previous sibling nodes.
// Previous sibling of a section is a section before the specified section.
// If the node is the first child, PreviousSibling will return null.
Node sectionBeforeLast = lastSection.getPreviousSibling();

if (sectionBeforeLast != null)
    doc.removeChild(sectionBeforeLast);

getNextSibling

→ inherited from Node
public Node getNextSibling()
Gets the node immediately following this node. If there is no next node, a null is returned.

Example:

Shows how to enumerate immediate child nodes of a composite node using NextSibling. In this example we enumerate all paragraphs of a section body.
// Get the section that we want to work on.
Section section = doc.getSections().get(0);
Body body = section.getBody();

// Loop starting from the first child until we reach null.
for (Node node = body.getFirstChild(); node != null; node = node.getNextSibling())
{
    // Output the types of the nodes that we come across.
    System.out.println(node.getNodeType());
}

Example:

Shows how to efficiently visit all direct and indirect children of a composite node.
public void RecurseAllNodes() throws Exception
{
    // Open a document.
    Document doc = new Document(getMyDir() + "Node.RecurseAllNodes.doc");

    // Invoke the recursive function that will walk the tree.
    TraverseAllNodes(doc);
}

/// <summary>
/// A simple function that will walk through all children of a specified node recursively
/// and print the type of each node to the screen.
/// </summary>
private void TraverseAllNodes(CompositeNode parentNode)
{
    // This is the most efficient way to loop through immediate children of a node.
    for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling())
    {
        // Do some useful work.
        System.out.println(childNode.getNodeType());

        // Recurse into the node if it is a composite node.
        if (childNode.isComposite())
            TraverseAllNodes((CompositeNode)childNode);
    }
}

isComposite

→ inherited from Node
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 efficiently visit all direct and indirect children of a composite node.
public void RecurseAllNodes() throws Exception
{
    // Open a document.
    Document doc = new Document(getMyDir() + "Node.RecurseAllNodes.doc");

    // Invoke the recursive function that will walk the tree.
    TraverseAllNodes(doc);
}

/// <summary>
/// A simple function that will walk through all children of a specified node recursively
/// and print the type of each node to the screen.
/// </summary>
private void TraverseAllNodes(CompositeNode parentNode)
{
    // This is the most efficient way to loop through immediate children of a node.
    for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling())
    {
        // Do some useful work.
        System.out.println(childNode.getNodeType());

        // Recurse into the node if it is a composite node.
        if (childNode.isComposite())
            TraverseAllNodes((CompositeNode)childNode);
    }
}

getRange

deepClone

→ inherited from Node
public Node deepClone(boolean isCloneChildren)
              throws java.lang.Exception
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.

This method always performs a deep copy of the node. The isCloneChildren parameter specifies whether to perform copy all child nodes as well.

Parameters:
isCloneChildren - True to recursively clone the subtree under the specified node; false to clone only the node itself.
Returns:
The cloned node.

getAncestor

→ inherited from Node
public Node getAncestor(java.lang.Class ancestorType)
Gets the first ancestor of the specified object type.

The ancestor type matches if it is equal to ancestorType or derived from ancestorType.

Parameters:
ancestorType - The object type of the ancestor to retrieve.
Returns:
The ancestor of the specified type or null if no ancestor of this type was found.

getAncestor

→ inherited from Node
public Node getAncestor(int ancestorType)
Gets the first ancestor of the specified NodeType.
Parameters:
ancestorType - A NodeType value. The node type of the ancestor to retrieve.
Returns:
The ancestor of the specified type or null if no ancestor of this type was found.

remove

→ inherited from Node
public void remove()
           throws java.lang.Exception
Removes itself from the parent.

Example:

Shows how to remove all nodes of a specific type from a composite node. In this example we remove tables from a section body.
// Get the section that we want to work on.
Section section = doc.getSections().get(0);
Body body = section.getBody();

// Select the first child node in the body.
Node curNode = body.getFirstChild();

while (curNode != null)
{
    // Save the pointer to the next sibling node because if the current
    // node is removed from the parent in the next step, we will have
    // no way of finding the next node to continue the loop.
    Node nextNode = curNode.getNextSibling();

    // A section body can contain Paragraph and Table nodes.
    // If the node is a Table, remove it from the parent.
    if (curNode.getNodeType() == NodeType.TABLE)
        curNode.remove();

    // Continue going through child nodes until null (no more siblings) is reached.
    curNode = nextNode;
}

nextPreOrder

→ inherited from Node
public Node nextPreOrder(Node rootNode)
Gets next node according to the pre-order tree traversal algorithm.
Parameters:
rootNode - The top node (limit) of traversal.
Returns:
Next node in pre-order order. Null if reached the rootNode.

Example:

Shows how to delete all images from a document using pre-order tree traversal.
Node curNode = doc;
while (curNode != null)
{
    Node nextNode = curNode.nextPreOrder(doc);

    if (curNode.getNodeType() == NodeType.SHAPE)
    {
        Shape shape = (Shape)curNode;

        // Several shape types can have an image including image shapes and OLE objects.
        if (shape.canHaveImage())
            shape.remove();
    }

    curNode = nextNode;
}

previousPreOrder

→ inherited from Node
public Node previousPreOrder(Node rootNode)
Gets the previous node according to the pre-order tree traversal algorithm.
Parameters:
rootNode - The top node (limit) of traversal.
Returns:
Previous node in pre-order order. Null if reached the rootNode.

toTxt

→ inherited from Node
public java.lang.String toTxt()
            throws java.lang.Exception
Exports the content of the node into a string in plain text format.

This method removes field codes and Microsoft Word control characters, uses CrLf (or any other) combination of characters to mark ends of paragraphs in the resulting string. It produces a different result from getText() which just gets the text from the node without removing field codes or special characters.

Returns:
The content of the node in plain text format.

SaveOptions.TxtExportParagraphBreak, SaveOptions.TxtExportHeadersFooters

iterator

→ inherited from Node
public java.util.Iterator iterator()
Provides support for the for each style iteration over child nodes of the node.

Non-CompositeNodes (like Run, SpecialChar and so on) return Empty non-null iterator used internally for XPath traversal.
