Implements the CITATION field. Inserts the contents of the Source element with a specified Tag element using a bibliographic style.

Example:

Shows how to work with CITATION and BIBLIOGRAPHY fields.
// Open a document that has bibliographical sources
Document doc = new Document(getMyDir() + "Bibliography.docx");

// Add text that we can cite
DocumentBuilder builder = new DocumentBuilder(doc);
builder.write("Text to be cited with one source.");

// Create a citation field using the document builder
FieldCitation fieldCitation = (FieldCitation) builder.insertField(FieldType.FIELD_CITATION, true);

// A simple citation can have just the page number and author's name
fieldCitation.setSourceTag("Book1"); // We refer to sources using their tag names
fieldCitation.setPageNumber("85");
fieldCitation.setSuppressAuthor(false);
fieldCitation.setSuppressTitle(true);
fieldCitation.setSuppressYear(true);

Assert.assertEquals(" CITATION  Book1 \\p 85 \\t \\y", fieldCitation.getFieldCode());

// We can make a more detailed citation and make it cite 2 sources
builder.insertParagraph();
builder.write("Text to be cited with two sources.");
fieldCitation = (FieldCitation) builder.insertField(FieldType.FIELD_CITATION, true);
fieldCitation.setSourceTag("Book1");

Method Detail

getFieldCode

→ inherited from Field
public java.lang.String getFieldCode()
Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.

Example:

Shows how to insert a field into a document by 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
Assert.assertEquals(LocalDate.now().format(DateTimeFormatter.ofPattern("M/d/YYYY")), dateField.getResult());

// Display the field code which defines the behavior of the field. This can been seen in Microsoft Word by pressing ALT+F9
Assert.assertEquals("DATE \\* MERGEFORMAT", dateField.getFieldCode());

// The field type defines what type of field in the Document this is. In this case the type is "FieldDate" 
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();

Example:

Shows how to get text between field start and field separator (or field end if there is no separator).
// Open a document which contains a MERGEFIELD inside an IF field
Document doc = new Document(getMyDir() + "Nested fields.docx");

// Get the outer IF field and print its full field code
FieldIf fieldIf = (FieldIf) doc.getRange().getFields().get(0);
System.out.println("Full field code including child fields:\n\t{fieldIf.GetFieldCode()}");

// All inner nested fields are printed by default
Assert.assertEquals(fieldIf.getFieldCode(), fieldIf.getFieldCode(true));

// Print the field code again but this time without the inner MERGEFIELD
System.out.println("Field code with nested fields omitted:\n\t{fieldIf.GetFieldCode(false)}");

getFieldCode

→ inherited from Field
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).
// Open a document which contains a MERGEFIELD inside an IF field
Document doc = new Document(getMyDir() + "Nested fields.docx");

// Get the outer IF field and print its full field code
FieldIf fieldIf = (FieldIf) doc.getRange().getFields().get(0);
System.out.println("Full field code including child fields:\n\t{fieldIf.GetFieldCode()}");

// All inner nested fields are printed by default
Assert.assertEquals(fieldIf.getFieldCode(), fieldIf.getFieldCode(true));

// Print the field code again but this time without the inner MERGEFIELD
System.out.println("Field code with nested fields omitted:\n\t{fieldIf.GetFieldCode(false)}");

remove

→ inherited from Field
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 insert a field into a document by 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
Assert.assertEquals(LocalDate.now().format(DateTimeFormatter.ofPattern("M/d/YYYY")), dateField.getResult());

// Display the field code which defines the behavior of the field. This can been seen in Microsoft Word by pressing ALT+F9
Assert.assertEquals("DATE \\* MERGEFORMAT", dateField.getFieldCode());

// The field type defines what type of field in the Document this is. In this case the type is "FieldDate" 
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();

unlink

→ inherited from Field
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

→ inherited from Field
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);

// 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
Assert.assertEquals(LocalDate.now().format(DateTimeFormatter.ofPattern("M/d/YYYY")), dateField.getResult());

// Display the field code which defines the behavior of the field. This can been seen in Microsoft Word by pressing ALT+F9
Assert.assertEquals("DATE \\* MERGEFORMAT", dateField.getFieldCode());

// The field type defines what type of field in the Document this is. In this case the type is "FieldDate" 
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

→ inherited from Field
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");
