  // The field type defines what type of field in the Document this is. In this case the type is "FieldDate"
  System.out.println(MessageFormat.format("FieldType: {0}", 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();

  Example:

  Shows how to get text between field start and field separator (or field end if there is no separator)

  Document doc = new Document(getMyDir() + "Field.FieldCode.docx");

          } else {
              fieldCode = fieldIf.getFieldCode(false);
          }
      }
  }

• getFieldCode

  public java.lang.String getFieldCode(boolean includeChildFieldCodes)

  Returns text between field start and field separator (or field end if there is no separator).

  Parameters:

  includeChildFieldCodes - True if child field codes should be included.

  Example:

  Shows how to get text between field start and field separator (or field end if there is no separator)

  Document doc = new Document(getMyDir() + "Field.FieldCode.docx");
  
  for (Field field : doc.getRange().getFields()) {

          FieldIf fieldIf = (FieldIf) field;
  
          String fieldCode = fieldIf.getFieldCode();
  
          if (containsNestedFields) {
              fieldCode = fieldIf.getFieldCode(true);
          } else {
              fieldCode = fieldIf.getFieldCode(false);
          }
      }
  }

• remove

  public Node remove()
             throws java.lang.Exception

  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.

  Example:

  Shows how to work with a document's field collection.

  public void fieldCollection() throws Exception {
      // Open a document that has fields
      Document doc = new Document(getMyDir() + "Document.ContainsFields.docx");
  
      // Get the collection that contains all the fields in a document
      FieldCollection fields = doc.getRange().getFields();
      Assert.assertEquals(fields.getCount(), 6);
  
      // 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.");
          }
      }
  
      System.out.println(fieldVisitor.getText());
  
      // Get a field to remove itself
      fields.get(0).remove();
      Assert.assertEquals(fields.getCount(), 5);
  
      // Remove a field by reference
      Field lastField = fields.get(3);
      fields.remove(lastField);
      Assert.assertEquals(fields.getCount(), 4);
  
      // Remove a field by index
      fields.removeAt(2);
      Assert.assertEquals(fields.getCount(), 3);
  
      // Remove all fields from the document
      fields.clear();
      Assert.assertEquals(fields.getCount(), 0);

  Example:

  Inserts a field into a document using DocumentBuilder and FieldCode.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Insert a simple Date field into the document.
  // When we insert a field through the DocumentBuilder class we can get the
  // special Field object which contains information about the field.
  Field dateField = builder.insertField("DATE \\* MERGEFORMAT");
  
  // 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.
  System.out.println(MessageFormat.format("FieldResult: {0}", dateField.getResult()));
  
  // Display the field code which defines the behaviour of the field. This can been seen in Microsoft Word by pressing ALT+F9.
  System.out.println(MessageFormat.format("FieldCode: {0}", dateField.getFieldCode()));
  
  // The field type defines what type of field in the Document this is. In this case the type is "FieldDate"
  System.out.println(MessageFormat.format("FieldType: {0}", 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();

• 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() + "Field.UnlinkFields.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:

  Inserts a field into a document using DocumentBuilder and FieldCode.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Insert a simple Date field into the document.
  // When we insert a field through the DocumentBuilder class we can get the
  // special Field object which contains information about the field.
  Field dateField = builder.insertField("DATE \\* MERGEFORMAT");
  
  // 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.
  System.out.println(MessageFormat.format("FieldResult: {0}", dateField.getResult()));
  
  // Display the field code which defines the behaviour of the field. This can been seen in Microsoft Word by pressing ALT+F9.
  System.out.println(MessageFormat.format("FieldCode: {0}", dateField.getFieldCode()));
  
  // The field type defines what type of field in the Document this is. In this case the type is "FieldDate"
  System.out.println(MessageFormat.format("FieldType: {0}", 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.UpdateFieldIgnoringMergeFormat.docx", loadOptions);
  
  for (Field field : doc.getRange().getFields()) {
      if (((field.getType()) == (FieldType.FIELD_INCLUDE_PICTURE))) {
          FieldIncludePicture includePicture = (FieldIncludePicture) field;
          includePicture.setSourceFullName(getImageDir() + "dotnet-logo.png");
          includePicture.update(true);
      }
  }
  
  doc.updateFields();
  doc.save(getArtifactsDir() + "Field.UpdateFieldIgnoringMergeFormat.docx");
