    public abstract class Inline 
    extends Node

Base class for inline-level nodes that can have character formatting associated with them, but cannot have child nodes of their own.

A class derived from Inline can be a child of Paragraph.

Example:

Shows how to determine the revision type of an inline node.
Document doc = new Document(getMyDir() + "Revision runs.docx");

// When we edit the document while the "Track Changes" option, found in via Review -> Tracking,
// is turned on in Microsoft Word, the changes we apply count as revisions.
// When editing a document using Aspose.Words, we can begin tracking revisions by
// invoking the document's "StartTrackRevisions" method and stop tracking by using the "StopTrackRevisions" method.
// We can either accept revisions to assimilate them into the document
// or reject them to change the proposed change effectively.
Assert.assertEquals(6, doc.getRevisions().getCount());

// The parent node of a revision is the run that the revision concerns. A Run is an Inline node.
Run run = (Run) doc.getRevisions().get(0).getParentNode();

Paragraph firstParagraph = run.getParentParagraph();
RunCollection runs = firstParagraph.getRuns();

Assert.assertEquals(runs.getCount(), 6);

// Below are five types of revisions that can flag an Inline node.
// 1 -  An "insert" revision:
// This revision occurs when we insert text while tracking changes.
Assert.assertTrue(runs.get(2).isInsertRevision());

// 2 -  A "format" revision:
// This revision occurs when we change the formatting of text while tracking changes.
Assert.assertTrue(runs.get(2).isFormatRevision());

// 3 -  A "move from" revision:
// When we highlight text in Microsoft Word, and then drag it to a different place in the document
// while tracking changes, two revisions appear.
// The "move from" revision is a copy of the text originally before we moved it.
Assert.assertTrue(runs.get(4).isMoveFromRevision());

// 4 -  A "move to" revision:
// The "move to" revision is the text that we moved in its new position in the document.
// "Move from" and "move to" revisions appear in pairs for every move revision we carry out.
// Accepting a move revision deletes the "move from" revision and its text,
// and keeps the text from the "move to" revision.
// Rejecting a move revision conversely keeps the "move from" revision and deletes the "move to" revision.
Assert.assertTrue(runs.get(1).isMoveToRevision());

// 5 -  A "delete" revision:
// This revision occurs when we delete text while tracking changes. When we delete text like this,
// it will stay in the document as a revision until we either accept the revision,
// which will delete the text for good, or reject the revision, which will keep the text we deleted where it was.
Assert.assertTrue(runs.get(5).isDeleteRevision());

      • 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:");

      • 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());
      • getFont

        public Font getFont()
        
        Provides access to the font formatting of this object.

        Example:

        Shows how to construct an Aspose.Words document by hand.
        Document doc = new Document();
        
        // A blank document contains one section, one body and one paragraph.
        // Call the "RemoveAllChildren" method to remove all those nodes,
        // and end up with a document node with no children.
        doc.removeAllChildren();
        
        // This document now has no composite child nodes that we can add content to.
        // 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.
        Section section = new Section(doc);

        // on the page between the section's header and footer.
        Body body = new Body(doc);
        section.appendChild(body);
        
        // Create a paragraph, set some formatting properties, and then append it as a child to the body.

      • 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.

        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.

        Example:

        Shows how to clone a composite node.
        Document doc = new Document();
        Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();
        para.appendChild(new Run(doc, "Hello world!"));
        
        // Below are two ways of cloning a composite node.
        // 1 -  Create a clone of a node, and create a clone of each of its child nodes as well.
        Node cloneWithChildren = para.deepClone(true);
