FieldEnd
Inheritance: java.lang.Object, com.aspose.words.Node, com.aspose.words.Inline, com.aspose.words.SpecialChar, com.aspose.words.FieldChar
public class FieldEnd extends FieldChar
Represents an end of a Word field in a document.
To learn more, visit the Working with Fields documentation article.
Remarks:
FieldEnd is an inline-level node and represented by the ControlChar.FIELD_END_CHAR control character in the document.
FieldEnd 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.
Examples:
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 ");

// 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.

|---|---|---|
| rootNode | Node | The top node (limit) of traversal. |
Returns: Node - Previous node in pre-order order. Null if reached the rootNode .
remove()
public void remove()
Removes itself from the parent.
Examples:
Shows how to remove all child nodes of a specific type from a composite node.
Document doc = new Document(getMyDir() + "Tables.docx");
Assert.assertEquals(2, doc.getChildNodes(NodeType.TABLE, true).getCount());
Node curNode = doc.getFirstSection().getBody().getFirstChild();
while (curNode != null) {
// Save the next sibling node as a variable in case we want to move to it after deleting this node.
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();
}
curNode = nextNode;
}
Assert.assertEquals(0, doc.getChildNodes(NodeType.TABLE, true).getCount());
Shows how to delete all shapes with images from a document.
Document doc = new Document(getMyDir() + "Images.docx");
ArrayList shapes = (ArrayList) IterableUtils.toList(doc.getChildNodes(NodeType.SHAPE, true));
Assert.assertEquals(9, IterableUtils.countMatches(shapes, s -> {
try {

removeMoveRevisions()
public void removeMoveRevisions()
removeRunAttr(int key)
public void removeRunAttr(int key)
Parameters:
| Parameter | Type | Description |
|---|---|---|
| key | int |
setCustomNodeId(int value)
public void setCustomNodeId(int value)
Specifies custom node identifier.
Remarks:
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.
Examples:
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(NodeType.ANY, false);
Assert.assertEquals(3, paragraph.getChildNodes(NodeType.ANY, false).getCount());
for (Node child : (Iterable) children)
switch (child.getNodeType()) {
case NodeType.RUN:
System.out.println("Run contents:");
System.out.println(MessageFormat.format("\t\"{0}\"", child.getText().trim()));
break;
case NodeType.SHAPE:
Shape childShape = (Shape)child;
System.out.println("Shape:");
System.out.println(MessageFormat.format("\t{0}, {1}x{2}", childShape.getShapeType(), childShape.getWidth(), childShape.getHeight()));
break;
}
Parameters:
| Parameter | Type | Description |
|---|---|---|
| value | int | The corresponding int value. |
setRunAttr(int key, Object value)
public void setRunAttr(int key, Object value)
Parameters:
| Parameter | Type | Description |
|---|---|---|
| key | int | |
| value | java.lang.Object |
toString()
public String toString()
Returns: java.lang.String
toString(SaveOptions saveOptions)
public String toString(SaveOptions saveOptions)
Exports the content of the node into a string using the specified save options.
Examples:
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,
// it converts the node's contents to their raw html representation.
Assert.assertEquals(" " +
"Hello World!" +
"", 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(" " +
"Hello World!" +
"", node.toString(saveOptions));
Parameters:
| Parameter | Type | Description |
|---|---|---|
| saveOptions | SaveOptions | Specifies the options that control how the node is saved. |
Returns: java.lang.String - The content of the node in the specified format.
toString(int saveFormat)
public String toString(int saveFormat)
Parameters:
| Parameter | Type | Description |
|---|---|---|
| saveFormat | int |
Returns: java.lang.String
