public class FieldCitation 
extends Field

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() + "Document.HasBibliography.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 field = (FieldCitation) builder.insertField(FieldType.FIELD_CITATION, true);

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

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

// We can make a more detailed citation and make it cite 2 sources
builder.write("Text to be cited with two sources.");
field = (FieldCitation) builder.insertField(FieldType.FIELD_CITATION, true);
field.setSourceTag("Book1");
field.setAnotherSourceTag("Book2");
field.setFormatLanguageId("en-US");
field.setPageNumber("19");
field.setPrefix("Prefix ");
field.setSuffix(" Suffix");
field.setSuppressAuthor(false);
field.setSuppressTitle(false);
field.setSuppressYear(false);
field.setVolumeNumber("VII");

Assert.assertEquals(field.getFieldCode(), " CITATION  Book1 \\m Book2 \\l en-US \\p 19 \\f \"Prefix \" \\s \" Suffix\" \\v VII");

// Insert a new page which will contain our bibliography
builder.insertBreak(BreakType.PAGE_BREAK);

// All our sources can be displayed using a BIBLIOGRAPHY field
FieldBibliography fieldBibliography = (FieldBibliography) builder.insertField(FieldType.FIELD_BIBLIOGRAPHY, true);
fieldBibliography.setFormatLanguageId("1124");

Assert.assertEquals(fieldBibliography.getFieldCode(), " BIBLIOGRAPHY  \\l 1124");

doc.updateFields();
doc.save(getArtifactsDir() + "Field.Citation.docx");

        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:

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

        Example:

        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();

        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");
