remove()

public Node remove()

Removes the field from the document. Returns a node right after the field. If the field’s end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns null .

Examples:

Shows how to remove fields from a field collection.


 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();

 FieldCollection fields = doc.getRange().getFields();

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

 // Below are four ways of removing fields from a field collection.
 // 1 -  Get a field to remove itself:
 fields.get(0).remove();
 Assert.assertEquals(5, fields.getCount());

 // 2 -  Get the collection to remove a field that we pass to its removal method:
 Field lastField = fields.get(3);
 fields.remove(lastField);
 Assert.assertEquals(4, fields.getCount());

 // 3 -  Remove a field from a collection at an index:
 fields.removeAt(2);
 Assert.assertEquals(3, fields.getCount());

 // 4 -  Remove all the fields from the collection at once:
 fields.clear();
 Assert.assertEquals(0, fields.getCount());

Shows how to process PRIVATE fields.


 public void fieldPrivate() throws Exception {

     Document doc = new Document(getMyDir() + "Field sample - PRIVATE.docx");

     // WordPerfect 5.x/6.x documents like the one we have loaded may contain PRIVATE fields.

     // These fields are not a viable way of protecting sensitive information.
     // Unless backward compatibility with older versions of WordPerfect is essential,
     // we can safely remove these fields. We can do this using a DocumentVisiitor implementation.
     Assert.assertEquals(2, doc.getRange().getFields().getCount());

     FieldPrivateRemover remover = new FieldPrivateRemover();

setLocaleId(int value)

public void setLocaleId(int value)

Sets the LCID of the field.

Examples:

Shows how to insert a field and work with its locale.


 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 // Insert a DATE field, and then print the date it will display.
 // Your thread's current culture determines the formatting of the date.
 Field field = builder.insertField("DATE");
 System.out.println(MessageFormat.format("Today''s date, as displayed in the \"{0}\" culture: {1}", Locale.getDefault().getDisplayLanguage(), field.getResult()));

 Assert.assertEquals(1033, field.getLocaleId());
 // Changing the culture of our thread will impact the result of the DATE field.
 // Another way to get the DATE field to display a date in a different culture is to use its LocaleId property.
 // This way allows us to avoid changing the thread's culture to get this effect.
 doc.getFieldOptions().setFieldUpdateCultureSource(FieldUpdateCultureSource.FIELD_CODE);
 CultureInfo de = new CultureInfo("de-DE");
 field.setLocaleId(1031);
 field.update();

 System.out.println(MessageFormat.format("Today''s date, as displayed according to the \"{0}\" culture: {1}", Locale.forLanguageTag(LocaleUtil.getLocaleFromLCID(field.getLocaleId())).getDisplayLanguage(), field.getResult()));

Parameters:

ParameterTypeDescription
valueintThe LCID of the field.

setResult(String value)

public void setResult(String value)

Parameters:

ParameterTypeDescription
valuejava.lang.StringText that is between the field separator and field end.
public boolean unlink()

Performs the field unlink.

Remarks:

Replaces the field with its most recent result.

Some fields, such as XE (Index Entry) fields and SEQ (Sequence) fields, cannot be unlinked.

Examples:

Shows how to unlink a field.


 Document doc = new Document(getMyDir() + "Linked fields.docx");
 doc.getRange().getFields().get(1).unlink();

Returns: boolean - true if the field has been unlinked, otherwise false .

update()

public void update()

Performs the field update. Throws if the field is being updated already.

Examples:

Shows how to insert a field into a document using FieldType.


 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 // Insert two fields while passing a flag which determines whether to update them as the builder inserts them.
 // In some cases, updating fields could be computationally expensive, and it may be a good idea to defer the update.
 doc.getBuiltInDocumentProperties().setAuthor("John Doe");
 builder.write("This document was written by ");
 builder.insertField(FieldType.FIELD_AUTHOR, updateInsertedFieldsImmediately);

 builder.insertParagraph();
 builder.write("\nThis is page ");

 Field field = builder.insertField("= 2 + 3");

 Assert.assertEquals("= 2 + 3", field.getFieldCode());
 Assert.assertEquals("5", field.getResult());

 // We can apply a format to a field's result using the field's properties.
 // Below are three types of formats that we can apply to a field's result.
 // 1 -  Numeric format:

 format.setNumericFormat("$###.00");
 field.update();

 Assert.assertEquals("= 2 + 3 \\# $###.00", field.getFieldCode());

 format.setDateTimeFormat("dddd, MMMM dd, yyyy");
 field.update();

 Assert.assertEquals("DATE \\@ \"dddd, MMMM dd, yyyy\"", field.getFieldCode());
 System.out.println("Today's date, in {format.DateTimeFormat} format:\n\t{field.Result}");

 // 3 -  General format:

 format = field.getFormat();
 format.getGeneralFormats().add(GeneralFormat.LOWERCASE_ROMAN);
 format.getGeneralFormats().add(GeneralFormat.UPPER);
 field.update();
