public class FieldIndex 
extends Field

Implements the INDEX field.
Builds an index using the index entries specified by XE fields, and inserts that index at this place in the document.

Example:

Shows how to omit entries while populating an INDEX field with entries from XE fields.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Create an INDEX field which will display the page locations of XE fields in the document body
FieldIndex index = (FieldIndex) builder.insertField(FieldType.FIELD_INDEX, true);

// Set these attributes so that an XE field shows up in the INDEX field's result
// only if it is within the bounds of a bookmark named "MainBookmark", and is of type "A"
index.setBookmarkName("MainBookmark");
index.setEntryType("A");

Assert.assertEquals(" INDEX  \\b MainBookmark \\f A", index.getFieldCode());

// Our index will take up the first page
builder.insertBreak(BreakType.PAGE_BREAK);

// Start the bookmark that will contain all eligible XE entries
builder.startBookmark("MainBookmark");

// This entry will be picked up by the INDEX field because it is inside the bookmark
// and its type matches the INDEX field's type
// Note that even though the type is a string, it is defined by only the first character
FieldXE indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Index entry 1");
indexEntry.setEntryType("A");

Assert.assertEquals(" XE  \"Index entry 1\" \\f A", indexEntry.getFieldCode());

// Insert an XE field that will not appear in the INDEX field because it is of the wrong type
builder.insertBreak(BreakType.PAGE_BREAK);
indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Index entry 2");
indexEntry.setEntryType("B");

// End the bookmark and insert an XE field afterwards
// It is of the same type as the INDEX field, but will not appear since it is outside of the bookmark
// Note that the INDEX field itself does not have to be within its bookmark
builder.endBookmark("MainBookmark");
builder.insertBreak(BreakType.PAGE_BREAK);
indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Index entry 3");
indexEntry.setEntryType("A");

doc.updateFields();
doc.save(getArtifactsDir() + "Field.INDEX.XE.Filtering.docx");

Example:

Shows how to modify an INDEX field's appearance while populating it with XE field entries.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Create an INDEX field which will display the page locations of XE fields in the document body
FieldIndex index = (FieldIndex) builder.insertField(FieldType.FIELD_INDEX, true);
index.setLanguageId("1033");

// Setting this attribute's value to "A" will group all the entries by their first letter
// and place that letter in uppercase above each group
index.setHeading("A");

// Set the table created by the INDEX field to span over 2 columns
index.setNumberOfColumns("2");

// Set any entries with starting letters outside the "a-c" character range to be omitted
index.setLetterRange("a-c");

Assert.assertEquals(" INDEX  \\z 1033 \\h A \\c 2 \\p a-c", index.getFieldCode());

// These next two XE fields will show up under the "A" heading,
// with their respective text stylings also applied to their page numbers 
builder.insertBreak(BreakType.PAGE_BREAK);
FieldXE indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Apple");
indexEntry.isItalic(true);

Assert.assertEquals(" XE  Apple \\i", indexEntry.getFieldCode());

builder.insertBreak(BreakType.PAGE_BREAK);
indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Apricot");
indexEntry.isBold(true);

Assert.assertEquals(" XE  Apricot \\b", indexEntry.getFieldCode());

// Both the next two XE fields will be under a "B" and "C" heading in the INDEX fields table of contents
builder.insertBreak(BreakType.PAGE_BREAK);
indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Banana");

builder.insertBreak(BreakType.PAGE_BREAK);
indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Cherry");

// All INDEX field entries are sorted alphabetically, so this entry will show up under "A" with the other two
builder.insertBreak(BreakType.PAGE_BREAK);
indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Avocado");

// This entry will be excluded because, starting with the letter "D", it is outside the "a-c" range
builder.insertBreak(BreakType.PAGE_BREAK);
indexEntry = (FieldXE) builder.insertField(FieldType.FIELD_INDEX_ENTRY, true);
indexEntry.setText("Durian");

        Example:

      • unlink

        public boolean unlink()
                      throws java.lang.Exception
        Performs the field unlink.

        Replaces the field with its most recent result.

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

        Returns:
        True if the field has been unlinked, otherwise false.

        Example:

        Shows how to unlink specific field.
        Document doc = new Document(getMyDir() + "Linked fields.docx");
        doc.getRange().getFields().get(1).unlink();
      • update

        public void update()
                   throws java.lang.Exception
        Performs the field update. Throws if the field is being updated already.

        Example:

        Shows how to insert a field into a document by FieldCode.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

        // Update this particular field in the document so we can get the FieldResult
        dateField.update();
        
        // Display some information from this field
        // The field result is where the last evaluated value is stored. This is what is displayed in the document
        // When field codes are not showing

        Assert.assertEquals(FieldType.FIELD_DATE, dateField.getType());
        
        // Finally let's completely remove the field from the document. This can easily be done by invoking the Remove method on the object
        dateField.remove();
      • update

        public void update(boolean ignoreMergeFormat)
                   throws java.lang.Exception
        Performs a field update. Throws if the field is being updated already.
        Parameters:
        ignoreMergeFormat - If true then direct field result formatting is abandoned, regardless of the MERGEFORMAT switch, otherwise normal update is performed.

        Example:

        Shows a way to update a field ignoring the MERGEFORMAT switch.
        LoadOptions loadOptions = new LoadOptions();
        {
            loadOptions.setPreserveIncludePictureField(true);
        }
        Document doc = new Document(getMyDir() + "Field sample - INCLUDEPICTURE.docx", loadOptions);
        
        for (Field field : doc.getRange().getFields()) {
            if (((field.getType()) == (FieldType.FIELD_INCLUDE_PICTURE))) {
                FieldIncludePicture includePicture = (FieldIncludePicture) field;
                includePicture.setSourceFullName(getImageDir() + "Transparent background logo.png");
                includePicture.update(true);
        
                doc.updateFields();
                doc.save(getArtifactsDir() + "Field.UpdateFieldIgnoringMergeFormat.docx");
