Class FieldSeparator

  • All Implemented Interfaces:
    java.lang.Cloneable
    public class FieldSeparator 
    extends FieldChar

Represents a Word field separator that separates the field code from the field result.

FieldSeparator is an inline-level node and represented by the ControlChar.FIELD_SEPARATOR_CHAR control character in the document.

FieldSeparator can only be a child of Paragraph.

A complete field in a Microsoft Word document is a complex structure consisting of a field start character, field code, field separator character, field result and field end character. Some fields only have field start, field code and field end.

To easily insert a new field into a document, use the DocumentBuilder.insertField(java.lang.String) method.

Example:

Shows how to work with a collection of fields.
public void fieldCollection() throws Exception
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    builder.insertField(" DATE \\@ \"dddd, d MMMM yyyy\" ");
    builder.insertField(" TIME ");
    builder.insertField(" REVNUM ");
    builder.insertField(" AUTHOR  \"John Doe\" ");
    builder.insertField(" SUBJECT \"My Subject\" ");
    builder.insertField(" QUOTE \"Hello world!\" ");
    doc.updateFields();

    // This collection stores all of a document's fields.
    FieldCollection fields = doc.getRange().getFields();

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

    // Iterate over the field collection, and print contents and type
    // of every field using a custom visitor implementation.
    FieldVisitor fieldVisitor = new FieldVisitor();

    Iterator<Field> fieldEnumerator = fields.iterator();

    while (fieldEnumerator.hasNext()) {
        if (fieldEnumerator.next() != null) {
            Field currentField = fieldEnumerator.next();

            currentField.getStart().accept(fieldVisitor);
            if (currentField.getSeparator() != null) {
                currentField.getSeparator().accept(fieldVisitor);
            }
            currentField.getEnd().accept(fieldVisitor);
        } else {
            System.out.println("There are no fields in the document.");
        }

    • Property Getters/Setters Detail

      • 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.
        // 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
System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));

// But the paragraph node knows its document
System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));

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

// The paragraph node is now a child of the Body node
System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));

      • getFieldType

        public int getFieldType()
        Returns the type of the field. The value of the property is FieldType integer constant.

        Shows how to work with a FieldStart node.
        Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

FieldDate field = (FieldDate) builder.insertField(FieldType.FIELD_DATE, true);
field.getFormat().setDateTimeFormat("dddd, MMMM dd, yyyy");
field.update();

FieldChar fieldStart = field.getStart();

Assert.assertEquals(FieldType.FIELD_DATE, fieldStart.getFieldType());
Assert.assertEquals(false, fieldStart.isDirty());
Assert.assertEquals(false, fieldStart.isLocked());

// Retrieve the facade object which represents the field in the document.
field = (FieldDate)fieldStart.getField();

Assert.assertEquals(false, field.isLocked());
Assert.assertEquals(" DATE  \\@ \"dddd, MMMM dd, yyyy\"", field.getFieldCode());

// Update the field to show the current date.
field.update();

      • getFont

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

        Example:

        Shows how to construct an Aspose Words document node by node.
        Document doc = new Document();

// A newly created blank document still comes one section, one body and one paragraph
// Calling this method will remove all those nodes to completely empty the document
doc.removeAllChildren();

// This document now has no composite nodes that content can be added to
// If we wish to edit it, we will need to repopulate its node collection,
// which we will start to do with by creating a new Section node
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// A section needs a body, which will contain all other nodes that can be edited
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// Now we can begin adding content to the document
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);

Assert.assertEquals("Hello World!" + ControlChar.SECTION_BREAK_CHAR, doc.getText());

doc.save(getArtifactsDir() + "Section.CreateFromScratch.docx");

      • 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 efficiently visit all direct and indirect children of a composite node.
        public void recurseAllNodes() throws Exception {
    Document doc = new Document(getMyDir() + "Paragraphs.docx");

    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) {
    // Loop through immediate children of a node
    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
        if (childNode.isComposite()) {
            System.out.println();
            traverseAllNodes((CompositeNode) childNode, depth + 1);
        } else if (childNode instanceof Inline) {
            System.out.println(" - \"{childNode.GetText().Trim()}\"");

        }
    }
}

      • isDeleteRevision

        public boolean isDeleteRevision()

// Get the parent paragraph
Paragraph firstParagraph = run.getParentParagraph();
RunCollection runs = firstParagraph.getRuns();

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

// The text in the run at index #2 was typed after revisions were tracked, so it will count as an insert revision
// The font was changed, so it will also be a format revision
Assert.assertTrue(runs.get(2).isInsertRevision());
Assert.assertTrue(runs.get(2).isFormatRevision());

// If one node was moved from one place to another while changes were tracked,
// the node will be placed at the departure location as a "move to revision",
// and a "move from revision" node will be left behind at the origin, in case we want to reject changes
// Highlighting text and dragging it to another place with the mouse and cut-and-pasting (but not copy-pasting) both count as "move revisions"
// The node with the "IsMoveToRevision" flag is the arrival of the move operation, and the node with the "IsMoveFromRevision" flag is the departure point
Assert.assertTrue(runs.get(1).isMoveToRevision());
Assert.assertTrue(runs.get(4).isMoveFromRevision());

// If an Inline node gets deleted while changes are being tracked, it will leave behind a node with the IsDeleteRevision flag set to true until changes are accepted

        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.
        Document doc = new Document();

// Get the document's first paragraph and append a child node to it in the form of a run with text
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();

// When inserting a new node, the document that the node will belong to must be provided as an argument
Run run = new Run(doc, "Hello world!");
para.appendChild(run);

// The node lineage can be traced back to the document itself
Assert.assertEquals(para, run.getParentNode());
Assert.assertEquals(doc.getFirstSection().getBody(), para.getParentNode());
Assert.assertEquals(doc.getFirstSection(), doc.getFirstSection().getBody().getParentNode());
Assert.assertEquals(doc, doc.getFirstSection().getParentNode());

        Example:

        Shows how to create a node and set its owning document.
        // 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
System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));

// But the paragraph node knows its document
System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));

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

// The paragraph node is now a child of the Body node
System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));

      • getParentParagraph

        public Paragraph getParentParagraph()
        Retrieves the parent Paragraph of this node.

        Example:

        Shows how to view revision-related properties of Inline nodes.
        Document doc = new Document(getMyDir() + "Revision runs.docx");

// This document has 6 revisions
Assert.assertEquals(doc.getRevisions().getCount(), 6);

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

// Get the parent paragraph
Paragraph firstParagraph = run.getParentParagraph();
RunCollection runs = firstParagraph.getRuns();

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

// The text in the run at index #2 was typed after revisions were tracked, so it will count as an insert revision
// The font was changed, so it will also be a format revision
Assert.assertTrue(runs.get(2).isInsertRevision());
Assert.assertTrue(runs.get(2).isFormatRevision());

// If one node was moved from one place to another while changes were tracked,
// the node will be placed at the departure location as a "move to revision",
// and a "move from revision" node will be left behind at the origin, in case we want to reject changes
// Highlighting text and dragging it to another place with the mouse and cut-and-pasting (but not copy-pasting) both count as "move revisions"
// The node with the "IsMoveToRevision" flag is the arrival of the move operation, and the node with the "IsMoveFromRevision" flag is the departure point
Assert.assertTrue(runs.get(1).isMoveToRevision());
Assert.assertTrue(runs.get(4).isMoveFromRevision());

// If an Inline node gets deleted while changes are being tracked, it will leave behind a node with the IsDeleteRevision flag set to true until changes are accepted
Assert.assertTrue(runs.get(5).isDeleteRevision());

      • getPreviousSibling

        public Node getPreviousSibling()
        Gets the node immediately preceding this node. If there is no preceding node, a null is returned.

        Example:

        Shows how to use of methods of Node and CompositeNode to remove a section before the last section in the document.
        Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Create a second section by inserting a section break and add text to both sections
builder.writeln("Section 1 text.");
builder.insertBreak(BreakType.SECTION_BREAK_CONTINUOUS);
builder.writeln("Section 2 text.");

// Both sections are siblings of each other
Section lastSection = (Section) doc.getLastChild();
Section firstSection = (Section) lastSection.getPreviousSibling();

// Remove a section based on its sibling relationship with another section
if (lastSection.getPreviousSibling() != null)
    doc.removeChild(firstSection);

// The section we removed was the first one, leaving the document with only the second
Assert.assertEquals("Section 2 text.", doc.getText().trim());

      • getRange

        public Range getRange()
        Returns a Range object that represents the portion of a document that is contained in this node.

        Example:

        Shows how to delete all characters of a range.
        // Insert two sections into a blank document
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.write("Section 1. ");
builder.insertBreak(BreakType.SECTION_BREAK_CONTINUOUS);
builder.write("Section 2.");

// Verify the whole text of the document
Assert.assertEquals("Section 1. \fSection 2.", doc.getText().trim());

// Delete the first section from the document
doc.getSections().get(0).getRange().delete();

// Check the first section was deleted by looking at the text of the whole document again
Assert.assertEquals("Section 2.", doc.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.

        Example:

        Exports the content of a node to String in HTML format.
        Document doc = new Document(getMyDir() + "Document.docx");

// Extract the last paragraph in the document to convert to HTML
Node node = doc.getLastSection().getBody().getLastParagraph();

// When ToString is called using the html SaveFormat overload then the node is converted directly to html
Assert.assertEquals("<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%; font-size:12pt\">" +
        "<span style=\"font-family:'Times New Roman'\">Hello World!</span>" +
        "</p>", node.toString(SaveFormat.HTML));

// We can also modify the result of this conversion using a SaveOptions object
HtmlSaveOptions saveOptions = new HtmlSaveOptions();
saveOptions.setExportRelativeFontSize(true);

Assert.assertEquals("<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%\">" +
        "<span style=\"font-family:'Times New Roman'\">Hello World!</span>" +
        "</p>", node.toString(saveOptions));

        Example:

        Shows the difference between calling the GetText and ToString methods on a node.
        Document doc = new Document();

DocumentBuilder builder = new DocumentBuilder(doc);
builder.insertField("MERGEFIELD Field");

// GetText will retrieve the visible text as well as field codes and special characters.
Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());

// ToString will give us the document's appearance if saved to a passed save format.
Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));
