Property Getters/Setters Detail

• getConnection/setConnection

  public java.lang.String getConnection() / public void setConnection(java.lang.String value)
  

  Gets or sets a connection to the data.

  Example:

  Shows how to extract data from a database and insert it as a field into a document.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // This DATABASE field will run a query on a database, and display the result in a table.
  FieldDatabase field = (FieldDatabase)builder.insertField(FieldType.FIELD_DATABASE, true);

• 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");
  
  Assert.assertEquals("= 2 + 3", field.getFieldCode());
  Assert.assertEquals("5", field.getResult());
  
  // We can apply a format to a field's result using the field's attributes.
  // Below are three types of formats that we can apply to a field's result.
  // 1 -  Numeric format:
  FieldFormat format = field.getFormat();
  format.setNumericFormat("$###.00");
  field.update();
  
  Assert.assertEquals("= 2 + 3 \\# $###.00", field.getFieldCode());
  Assert.assertEquals("$  5.00", field.getResult());
  
  // 2 -  Date/time format:
  field = builder.insertField("DATE");
  format = field.getFormat();
  format.setDateTimeFormat("dddd, MMMM dd, yyyy");
  field.update();
  
  Assert.assertEquals("DATE \\@ \"dddd, MMMM dd, yyyy\"", field.getFieldCode());
  System.out.println("Today's date, in {format.DateTimeFormat} format:\n\t{field.Result}");
  
  // 3 -  General format:
  field = builder.insertField("= 25 + 33");
  format = field.getFormat();
  format.getGeneralFormats().add(GeneralFormat.LOWERCASE_ROMAN);
  format.getGeneralFormats().add(GeneralFormat.UPPER);
  field.update();
  
  int index = 0;
  Iterator<Integer> generalFormatEnumerator = format.getGeneralFormats().iterator();
  while (generalFormatEnumerator.hasNext()) {
      int value = generalFormatEnumerator.next();
      System.out.println(MessageFormat.format("General format index {0}: {1}", index++, value));
  }
  
  Assert.assertEquals("= 25 + 33 \\* roman \\* Upper", field.getFieldCode());
  Assert.assertEquals("LVIII", field.getResult());
  Assert.assertEquals(2, format.getGeneralFormats().getCount());
  Assert.assertEquals(GeneralFormat.LOWERCASE_ROMAN, format.getGeneralFormats().get(0));
  
  // We can remove our formats to revert the field's result to its original form.
  format.getGeneralFormats().remove(GeneralFormat.LOWERCASE_ROMAN);
  format.getGeneralFormats().removeAt(0);
  Assert.assertEquals(0, format.getGeneralFormats().getCount());
  field.update();
  
  Assert.assertEquals("= 25 + 33  ", field.getFieldCode());
  Assert.assertEquals("58", field.getResult());
  Assert.assertEquals(0, format.getGeneralFormats().getCount());

  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.
  // Not all field types require updating, exceptions include BARCODE and MERGEFIELD.
  doc.getBuiltInDocumentProperties().setAuthor("John Doe");
  builder.write("This document was written by ");
  builder.insertField(FieldType.FIELD_AUTHOR, updateInsertedFieldsImmediately);
  
  builder.insertParagraph();
  builder.write("\nThis is page ");
  builder.insertField(FieldType.FIELD_PAGE, updateInsertedFieldsImmediately);
  
  Assert.assertEquals(" AUTHOR ", doc.getRange().getFields().get(0).getFieldCode());
  Assert.assertEquals(" PAGE ", doc.getRange().getFields().get(1).getFieldCode());
  
  if (updateInsertedFieldsImmediately)
  {
      Assert.assertEquals("John Doe", doc.getRange().getFields().get(0).getResult());
      Assert.assertEquals("1", doc.getRange().getFields().get(1).getResult());
  }
  else
  {
      Assert.assertEquals("", doc.getRange().getFields().get(0).getResult());
      Assert.assertEquals("", doc.getRange().getFields().get(1).getResult());
  
      // We will need to update these fields using the update methods manually.
      doc.getRange().getFields().get(0).update();
  
      Assert.assertEquals("John Doe", doc.getRange().getFields().get(0).getResult());
  
  doc.updateFields();
  
  Assert.assertEquals("1", doc.getRange().getFields().get(1).getResult());
  }

• 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.
