      extended by com.aspose.words.FieldPrint

public class FieldPrint 
extends Field

Implements the PRINT field. An instruction to send the printer-specific control code characters to the selected printer when the document is printed.

Example:

Shows to insert a PRINT field.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.write("My paragraph");

// The PRINT field can send instructions to the printer that we use to print our document
FieldPrint field = (FieldPrint) builder.insertField(FieldType.FIELD_PRINT, true);

// Set the area for the printer to perform instructions over
// In this case it will be the paragraph that contains our PRINT field
field.setPostScriptGroup("para");

// When our document is printed using a printer that supports PostScript,
// this command will turn the entire area that we specified in field.PostScriptGroup white
field.setPrinterInstructions("erasepage");

Assert.assertEquals(field.getFieldCode(), " PRINT  erasepage \\p para");

builder.insertParagraph();

// PRINTDATE field will display "0/0/0000" by default
// When a document is printed by a printer or printed as a PDF (but not exported as PDF),
// these fields will display the date/time of the printing operation, in various calendars
FieldPrintDate fieldPrintDate = (FieldPrintDate) builder.insertField(FieldType.FIELD_PRINT_DATE, true);
fieldPrintDate.setUseLunarCalendar(true);
builder.writeln();

Assert.assertEquals(fieldPrintDate.getFieldCode(), " PRINTDATE  \\h");

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

for (Field field : doc.getRange().getFields()) {
    if (field.getType() == FieldType.FIELD_IF) {
        FieldIf fieldIf = (FieldIf) field;

        String fieldCode = fieldIf.getFieldCode();

        if (containsNestedFields) {
            fieldCode = fieldIf.getFieldCode(true);
        } else {
            fieldCode = 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 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);

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() + "Field.UnlinkFields.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:

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

→ 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.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");
