Property Getters/Setters Detail

• getCount

  public int getCount()
  

  Gets number of items in the collection.

  Example:

  Shows how to work with custom document properties.

  Document doc = new Document(getMyDir() + "Properties.docx");
  
  // Every document contains a collection of custom properties, which, like the built-in properties, are key-value pairs.
  // Unlike the built-in properties, many of which the document maintains by itself, we need to create all of our own custom properties. 
  Assert.assertEquals("Value of custom document property", doc.getCustomDocumentProperties().get("CustomProperty").toString());
  
  doc.getCustomDocumentProperties().add("CustomProperty2", "Value of custom document property #2");
  
  System.out.println("Custom Properties:");
  for (DocumentProperty customDocumentProperty : doc.getCustomDocumentProperties())
  {
      System.out.println(customDocumentProperty.getName());
      System.out.println(MessageFormat.format("\tType:\t{0}", customDocumentProperty.getType()));
      System.out.println(MessageFormat.format("\tValue:\t\"{0}\"", customDocumentProperty.getValue()));
  }

• get

  public DocumentProperty get(int index)
  

  Returns a DocumentProperty object by index.

  Note: In Java this method is slow because iterates over all nodes.

  Parameters:

  index - Zero-based index of the DocumentProperty to retrieve.

  Example:

  Shows how to work with custom document properties.

  Document doc = new Document(getMyDir() + "Properties.docx");
  
  // Every document contains a collection of custom properties, which, like the built-in properties, are key-value pairs.
  // Unlike the built-in properties, many of which the document maintains by itself, we need to create all of our own custom properties. 
  Assert.assertEquals("Value of custom document property", doc.getCustomDocumentProperties().get("CustomProperty").toString());
  
  doc.getCustomDocumentProperties().add("CustomProperty2", "Value of custom document property #2");
  
  System.out.println("Custom Properties:");
  for (DocumentProperty customDocumentProperty : doc.getCustomDocumentProperties())
  {
      System.out.println(customDocumentProperty.getName());
      System.out.println(MessageFormat.format("\tType:\t{0}", customDocumentProperty.getType()));
      System.out.println(MessageFormat.format("\tValue:\t\"{0}\"", customDocumentProperty.getValue()));
  }

• get

  public DocumentProperty get(java.lang.String name)
  

  Returns a DocumentProperty object by the name of the property.

  Returns null if a property with the specified name is not found.

  Parameters:

  name - The case-insensitive name of the property to retrieve.

  Example:

  Shows how to create a custom document property which contains a date and time.

  Document doc = new Document();
  
  doc.getCustomDocumentProperties().add("AuthorizationDate", new Date());
  
  System.out.println("Document authorized on {doc.CustomDocumentProperties[");

• removeAt

  public void removeAt(int index)

  Removes a property at the specified index.

  Note: In Java this method is slow because iterates over all nodes.

  Parameters:

  index - The zero based index.

  Example:

  Shows how to work with a document's custom properties.

  Document doc = new Document();
  CustomDocumentProperties properties = doc.getCustomDocumentProperties();
  
  Assert.assertEquals(0, properties.getCount());
  
  // Custom document properties are key-value pairs that we can add to the document.
  properties.add("Authorized", true);
  properties.add("Authorized By", "John Doe");
  properties.add("Authorized Date", new Date());
  properties.add("Authorized Revision", doc.getBuiltInDocumentProperties().getRevisionNumber());
  properties.add("Authorized Amount", 123.45);
  
  // The collection sorts the custom properties in alphabetic order.
  Assert.assertEquals(1, properties.indexOf("Authorized Amount"));
  Assert.assertEquals(5, properties.getCount());
  
  // Print every custom property in the document.
  Iterator<DocumentProperty> enumerator = properties.iterator();
  while (enumerator.hasNext()) {
      DocumentProperty property = enumerator.next();
      System.out.println(MessageFormat.format("Name: \"{0}\"\n\tType: \"{1}\"\n\tValue: \"{2}\"", property.getName(), property.getType(), property.getValue()));
  }
  
  // Display the value of a custom property using a DOCPROPERTY field.
  DocumentBuilder builder = new DocumentBuilder(doc);
  FieldDocProperty field = (FieldDocProperty)builder.insertField(" DOCPROPERTY \"Authorized By\"");
  field.update();
  
  Assert.assertEquals("John Doe", field.getResult());
  
  // We can find these custom properties in Microsoft Word via "File" -> "Properties" > "Advanced Properties" > "Custom".
  doc.save(getArtifactsDir() + "DocumentProperties.DocumentPropertyCollection.docx");
  
  // Below are three ways or removing custom properties from a document.
  // 1 -  Remove by index:
  properties.removeAt(1);
  
  Assert.assertFalse(properties.contains("Authorized Amount"));
  Assert.assertEquals(4, properties.getCount());
  
  // 2 -  Remove by name:
  properties.remove("Authorized Revision");
  
  Assert.assertFalse(properties.contains("Authorized Revision"));
  Assert.assertEquals(3, properties.getCount());
  
  // 3 -  Empty the entire collection at once:
  properties.clear();
  
  Assert.assertEquals(0, properties.getCount());
