  Gets or sets the comparison operator.

  Example:

  Shows how to skip pages in a mail merge using the SKIPIF field.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Insert a SKIPIF field. If the current row of a mail merge operation fulfills the condition
  // which the expressions of this field state, then the mail merge operation aborts the current row,
  // discards the current merge document, and then immediately moves to the next row to begin the next merge document.
  FieldSkipIf fieldSkipIf = (FieldSkipIf) builder.insertField(FieldType.FIELD_SKIP_IF, true);
  
  // Move the builder to the SKIPIF field's separator so we can place a MERGEFIELD inside the SKIPIF field.
  builder.moveTo(fieldSkipIf.getSeparator());
  FieldMergeField fieldMergeField = (FieldMergeField) builder.insertField(FieldType.FIELD_MERGE_FIELD, true);
  fieldMergeField.setFieldName("Department");

  // Add content to our document, create the data source, and execute the mail merge.
  builder.moveToDocumentEnd();

  // This table has three rows, and one of them fulfills the condition of our SKIPIF field. 
  // The mail merge will produce two pages.
  DataTable table = new DataTable("Employees");

  fieldMergeField.setFieldName("Name");
  fieldSkipIf.setLeftExpression("=");
  fieldSkipIf.setRightExpression("John Doe");
  
  // Create a data source with 3 rows, one of them having "John Doe" as a value for the "Name" column.

• getType

  public int getType()
  

  Gets the Microsoft Word field type. The value of the property is FieldType integer constant.

  Example:

  Shows how to insert a field into a document using a field code.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  Field dateField = builder.insertField("DATE \\* MERGEFORMAT");
  
  Assert.assertEquals(FieldType.FIELD_DATE, dateField.getType());
  Assert.assertEquals("DATE \\* MERGEFORMAT", dateField.getFieldCode());

Method Detail

• getFieldCode

  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 get a field's field code.

  // Open a document which contains a MERGEFIELD inside an IF field.
  Document doc = new Document(getMyDir() + "Nested fields.docx");
  FieldIf fieldIf = (FieldIf)doc.getRange().getFields().get(0);
  
  // There are two ways of getting a field's field code:
  // 1 -  Omit its inner fields:
  Assert.assertEquals(" IF  > 0 \" (surplus of ) \" \"\" ", fieldIf.getFieldCode(false));
  
  // 2 -  Include its inner fields:
  Assert.assertEquals(" IF \u0013 MERGEFIELD NetIncome \u0014\u0015 > 0 \" (surplus of \u0013 MERGEFIELD  NetIncome \\f $ \u0014\u0015) \" \"\" ",
      fieldIf.getFieldCode(true));
  
  // By default, the GetFieldCode method displays inner fields.
  Assert.assertEquals(fieldIf.getFieldCode(), fieldIf.getFieldCode(true));

  Example:

  Shows how to insert a field into a document using a field code.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  Field dateField = builder.insertField("DATE \\* MERGEFORMAT");
  
  Assert.assertEquals(FieldType.FIELD_DATE, dateField.getType());
  Assert.assertEquals("DATE \\* MERGEFORMAT", dateField.getFieldCode());

• 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 a field's field code.

  // Open a document which contains a MERGEFIELD inside an IF field.
  Document doc = new Document(getMyDir() + "Nested fields.docx");
  FieldIf fieldIf = (FieldIf)doc.getRange().getFields().get(0);
  
  // There are two ways of getting a field's field code:

  Assert.assertEquals(fieldIf.getFieldCode(), fieldIf.getFieldCode(true));

• 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 process PRIVATE fields.

  public void fieldPrivate() throws Exception
  {
      // Open a Corel WordPerfect document which we have converted to .docx format.
      Document doc = new Document(getMyDir() + "Field sample - PRIVATE.docx");

      // Microsoft Word preserves PRIVATE fields during load/save operations,

      // These fields are not a viable way of protecting sensitive information.
      // Unless backward compatibility with older versions of WordPerfect is essential,
      // we can safely remove these fields. We can do this using a DocumentVisiitor implementation.
      Assert.assertEquals(2, doc.getRange().getFields().getCount());
  
      FieldPrivateRemover remover = new FieldPrivateRemover();
      doc.accept(remover);
  
      Assert.assertEquals(remover.getFieldsRemovedCount(), 2);
      Assert.assertEquals(doc.getRange().getFields().getCount(), 0);

          }
  
          return VisitorAction.CONTINUE;

  Example:

  Shows how to remove fields from a field collection.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  builder.insertField(" DATE \\@ \"dddd, d MMMM yyyy\" ");
  builder.insertField(" TIME ");

  // This collection stores all of a document's fields.
  FieldCollection fields = doc.getRange().getFields();
  
  Assert.assertEquals(6, fields.getCount());
  
  // Below are four ways of removing fields from a field collection.
  // 1 -  Get a field to remove itself:
  fields.get(0).remove();
  Assert.assertEquals(5, fields.getCount());
  
  // 2 -  Get the collection to remove a field that we pass to its removal method:
  Field lastField = fields.get(3);

  // 3 -  Remove a field from a collection at an index:
  fields.removeAt(2);

  // 4 -  Remove all the fields from the collection at once:
  fields.clear();
  Assert.assertEquals(0, fields.getCount());

• 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 a field.

  Document doc = new Document(getMyDir() + "Linked fields.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:

  Shows how to format field results.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Use a document builder to insert a field that displays a result with no format applied.
  Field field = builder.insertField("= 2 + 3");

  field.update();
  
  Assert.assertEquals("= 25 + 33  ", field.getFieldCode());

  Example:

  Shows how to insert a field into a document using FieldType.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Insert two fields while passing a flag which determines whether to update them as the builder inserts them.
  // In some cases, updating fields could be computationally expensive, and it may be a good idea to defer the update.

  }

• 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.
