getFieldCode | → inherited from Field |
public java.lang.String getFieldCode() |
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 behavior 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();
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() + "Nested fields.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); } } }

unlink | → inherited from Field |
public boolean unlink() throws java.lang.Exception |
Replaces the field with its most recent result.
Some fields, such as XE (Index Entry) fields and SEQ (Sequence) fields, cannot be unlinked.
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 |
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.

update | → inherited from Field |
public void update(boolean ignoreMergeFormat) throws java.lang.Exception |
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 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");
