• getAuthor/setAuthor

  public java.lang.String getAuthor() / public void setAuthor(java.lang.String value)
  

  Gets or sets the name of the document's author.

  Example:

  Shows how to work with built-in document properties in the "Description" category.

  properties.setAuthor("John Doe");
  builder.write("Author:\t");
  builder.insertField(FieldType.FIELD_AUTHOR, true);
  
  // 2 -  "Title" property, which we can display using a TITLE field:

• getHeadingPairs/setHeadingPairs

  public java.lang.Object[] getHeadingPairs() / public void setHeadingPairs(java.lang.Object[] value)
  

  Specifies document headings and their names.

  Every heading pair occupies two elements in this array.

  The first element of the pair is a java.lang.String and specifies the heading name. The second element of the pair is an int and specifies the count of document parts for this heading in the TitlesOfParts property.

  The total sum of counts for all heading pairs in this property must be equal to the number of elements in the TitlesOfParts property.

  Aspose.Words does not update this property.

  Example:

  Shows the relationship between "HeadingPairs" and "TitlesOfParts" properties.

  Document doc = new Document(getMyDir() + "Heading pairs and titles of parts.docx");
  
  // We can find the combined values of these collections via "File" -> "Properties" -> "Advanced Properties" > "Contents" tab.
  // The HeadingPairs property is a collection of <string, int> pairs that determines
  // how many document parts a heading spans across.
  Object[] headingPairs = doc.getBuiltInDocumentProperties().getHeadingPairs();
  
  // The TitlesOfParts property contains the names of parts that belong to the above headings.
  String[] titlesOfParts = doc.getBuiltInDocumentProperties().getTitlesOfParts();
  
  int headingPairsIndex = 0;
  int titlesOfPartsIndex = 0;
  while (headingPairsIndex < headingPairs.length)
  {

  // The document we are trying to link to is in a different directory to the one we are planning to save the document in.
  // We could fix links like this by putting an absolute filename in each one. 
  // Alternatively, we could provide a base link that every hyperlink with a relative filename
  // will prepend to its link when we click on it. 
  BuiltInDocumentProperties properties = doc.getBuiltInDocumentProperties();
  properties.setHyperlinkBase(getMyDir());
  
  Assert.assertTrue(new File(properties.getHyperlinkBase() + ((FieldHyperlink)doc.getRange().getFields().get(0)).getAddress()).exists());

• getSecurity/setSecurity

  public int getSecurity() / public void setSecurity(int value)
  

  Specifies the security level of a document as a numeric value. The value of the property is DocumentSecurity integer constant.

  Use this property for informational purposes only because Microsoft Word does not always set this property. This property is available in DOC and OOXML documents only.

  To protect or unprotect a document use the Document.protect(int,java.lang.String) and Document.unprotect() methods.

  Aspose.Words updates this property to a correct value before saving a document.

  Example:

  Shows how to use document properties to display the security level of a document.

  Document doc = new Document();
  
  Assert.assertEquals(DocumentSecurity.NONE, doc.getBuiltInDocumentProperties().getSecurity());
  
  // If we configure a document to be read-only, it will display this status using the "Security" built-in property.
  doc.getWriteProtection().setReadOnlyRecommended(true);
  doc.save(getArtifactsDir() + "DocumentProperties.Security.ReadOnlyRecommended.docx");
  
  Assert.assertEquals(DocumentSecurity.READ_ONLY_RECOMMENDED, 
      new Document(getArtifactsDir() + "DocumentProperties.Security.ReadOnlyRecommended.docx").getBuiltInDocumentProperties().getSecurity());
  
  // Write-protect a document, and then verify its security level.
  doc = new Document();
  
  Assert.assertFalse(doc.getWriteProtection().isWriteProtected());
  
  doc.getWriteProtection().setPassword("MyPassword");
  
  Assert.assertTrue(doc.getWriteProtection().validatePassword("MyPassword"));
  Assert.assertTrue(doc.getWriteProtection().isWriteProtected());
  
  doc.save(getArtifactsDir() + "DocumentProperties.Security.ReadOnlyEnforced.docx");
  
  Assert.assertEquals(DocumentSecurity.READ_ONLY_ENFORCED,
      new Document(getArtifactsDir() + "DocumentProperties.Security.ReadOnlyEnforced.docx").getBuiltInDocumentProperties().getSecurity());
  
  // "Security" is a descriptive property. We can edit its value manually.
  doc = new Document();
  
  doc.protect(ProtectionType.ALLOW_ONLY_COMMENTS, "MyPassword");
  doc.getBuiltInDocumentProperties().setSecurity(DocumentSecurity.READ_ONLY_EXCEPT_ANNOTATIONS);
  doc.save(getArtifactsDir() + "DocumentProperties.Security.ReadOnlyExceptAnnotations.docx");
  
  Assert.assertEquals(DocumentSecurity.READ_ONLY_EXCEPT_ANNOTATIONS,
      new Document(getArtifactsDir() + "DocumentProperties.Security.ReadOnlyExceptAnnotations.docx").getBuiltInDocumentProperties().getSecurity());

• getSubject/setSubject

  public java.lang.String getSubject() / public void setSubject(java.lang.String value)

  Example:

  Shows how to work with built-in document properties in the "Description" category.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  BuiltInDocumentProperties properties = doc.getBuiltInDocumentProperties();
  
  // Below are four built-in document properties that have fields that can display their values in the document body.
  // 1 -  "Author" property, which we can display using an AUTHOR field:
  properties.setAuthor("John Doe");
  builder.write("Author:\t");
  builder.insertField(FieldType.FIELD_AUTHOR, true);
  
  // 2 -  "Title" property, which we can display using a TITLE field:
  properties.setTitle("John's Document");
  builder.write("\nDoc title:\t");
  builder.insertField(FieldType.FIELD_TITLE, true);
  
  // 3 -  "Subject" property, which we can display using a SUBJECT field:
  properties.setSubject("My subject");
  builder.write("\nSubject:\t");
  builder.insertField(FieldType.FIELD_SUBJECT, true);
  
  // 4 -  "Comments" property, which we can display using a COMMENTS field:
  properties.setComments(MessageFormat.format("This is {0}'s document about {1}", properties.getAuthor(), properties.getSubject()));
  builder.write("\nComments:\t\"");
  builder.insertField(FieldType.FIELD_COMMENTS, true);
  builder.write("\"");
  
  // The "Category" built-in property does not have a field that can display its value.
  properties.setCategory("My category");
  
  // We can set multiple keywords for a document by separating the string value of the "Keywords" property with semicolons.
  properties.setKeywords("Tag 1; Tag 2; Tag 3");
  
  // We can right-click this document in Windows Explorer and find these properties in "Properties" -> "Details".
  // The "Author" built-in property is in the "Origin" group, and the others are in the "Description" group.
  doc.save(getArtifactsDir() + "DocumentProperties.Description.docx");

• getTemplate/setTemplate

  public java.lang.String getTemplate() / public void setTemplate(java.lang.String value)
  

  Gets or sets the informational name of the document template.

  In Microsoft Word, this property is for informational purposes only and usually contains only the file name of the template without the path.

  Empty string means the document is attached to the Normal template.

  To get or set the actual name of the attached template, use the Document.AttachedTemplate property.

  Example:

  Shows how to work with document properties in the "Origin" category.

  // Open a document that we have created and edited using Microsoft Word.
  Document doc = new Document(getMyDir() + "Properties.docx");
  BuiltInDocumentProperties properties = doc.getBuiltInDocumentProperties();
  
  // The following built-in properties contain information regarding the creation and editing of this document.
  // We can right-click this document in Windows Explorer and find
  // these properties via "Properties" -> "Details" -> "Origin" category.
  // Fields such as PRINTDATE and EDITTIME can display these values in the document body.
  System.out.println(MessageFormat.format("Created using {0}, on {1}", properties.getNameOfApplication(), properties.getCreatedTime()));
  System.out.println(MessageFormat.format("Minutes spent editing: {0}", properties.getTotalEditingTime()));
  System.out.println(MessageFormat.format("Date/time last printed: {0}", properties.getLastPrinted()));
  System.out.println(MessageFormat.format("Template document: {0}", properties.getTemplate()));
  
  // We can also change the values of built-in properties.
  properties.setCompany("Doe Ltd.");
  properties.setManager("Jane Doe");
  properties.setVersion(5);
  properties.setRevisionNumber(properties.getRevisionNumber() + 1);
  
  // Microsoft Word updates the following properties automatically when we save the document.
  // To use these properties with Aspose.Words, we will need to set values for them manually.
  properties.setLastSavedBy("John Doe");
  properties.setLastSavedTime(new Date());
  
  // We can right-click this document in Windows Explorer and find these properties in "Properties" -> "Details" -> "Origin".
  doc.save(getArtifactsDir() + "DocumentProperties.Origin.docx");

• getThumbnail/setThumbnail

  public byte[] getThumbnail() / public void setThumbnail(byte[] value)
  

  Gets or sets the thumbnail of the document.

  For now this property is used only when a document is being exported to ePub, it's not read from and written to other document formats.

  Image of arbitrary format can be set to this property, but the format is checked during export. System.InvalidOperationException is thrown if the image is invalid or its format is unsupported for specific format of document.

  Only gif, jpeg and png images can be used for ePub publication.

  Example:

  Shows how to add a thumbnail to a document that we save as an Epub.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  builder.writeln("Hello world!");
  
  // If we save a document, whose "Thumbnail" property contains image data that we added, as an Epub,
  // a reader that opens that document may display the image before the first page.
  BuiltInDocumentProperties properties = doc.getBuiltInDocumentProperties();
  
  byte[] thumbnailBytes = DocumentHelper.getBytesFromStream(new FileInputStream(getImageDir() + "Logo.jpg"));
  properties.setThumbnail(thumbnailBytes);
  
  doc.save(getArtifactsDir() + "DocumentProperties.Thumbnail.epub");
  
  // We can extract a document's thumbnail image and save it to the local file system.
  DocumentProperty thumbnail = doc.getBuiltInDocumentProperties().get("Thumbnail");
  FileUtils.writeByteArrayToFile(new File(getArtifactsDir() + "DocumentProperties.Thumbnail.gif"), thumbnail.toByteArray());

• getTitle/setTitle

  public java.lang.String getTitle() / public void setTitle(java.lang.String value)
  

  Gets or sets the title of the document.

  Example:

  Shows how to work with built-in document properties in the "Description" category.

  Document doc = new Document();

  properties.setTitle("John's Document");
  builder.write("\nDoc title:\t");
  builder.insertField(FieldType.FIELD_TITLE, true);
  
  // 3 -  "Subject" property, which we can display using a SUBJECT field:
  properties.setSubject("My subject");
  builder.write("\nSubject:\t");
  builder.insertField(FieldType.FIELD_SUBJECT, true);
  
  // 4 -  "Comments" property, which we can display using a COMMENTS field:
  properties.setComments(MessageFormat.format("This is {0}'s document about {1}", properties.getAuthor(), properties.getSubject()));
  builder.write("\nComments:\t\"");
  builder.insertField(FieldType.FIELD_COMMENTS, true);
  builder.write("\"");
  
  // The "Category" built-in property does not have a field that can display its value.
  properties.setCategory("My category");
  
  // We can set multiple keywords for a document by separating the string value of the "Keywords" property with semicolons.

• getTitlesOfParts/setTitlesOfParts

  public java.lang.String[] getTitlesOfParts() / public void setTitlesOfParts(java.lang.String[] value)
  

  Each string in the array specifies the name of a part in the document.

  Aspose.Words does not update this property.

  Example:

  Shows the relationship between "HeadingPairs" and "TitlesOfParts" properties.

  Document doc = new Document(getMyDir() + "Heading pairs and titles of parts.docx");
  
  // We can find the combined values of these collections via "File" -> "Properties" -> "Advanced Properties" > "Contents" tab.
  // The HeadingPairs property is a collection of <string, int> pairs that determines
  // how many document parts a heading spans across.
  Object[] headingPairs = doc.getBuiltInDocumentProperties().getHeadingPairs();
  
  // The TitlesOfParts property contains the names of parts that belong to the above headings.
  String[] titlesOfParts = doc.getBuiltInDocumentProperties().getTitlesOfParts();
  
  int headingPairsIndex = 0;
  int titlesOfPartsIndex = 0;
  while (headingPairsIndex < headingPairs.length)
  {
      System.out.println(MessageFormat.format("Parts for {0}:", headingPairs[headingPairsIndex++]));
      int partsCount = (int)headingPairs[headingPairsIndex++];
  
      for (int i = 0; i < partsCount; i++)

• 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());

  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.

  The string names of the properties correspond to the names of the typed properties available from BuiltInDocumentProperties.

  If you request a property that is not present in the document, but the name of the property is recognized as a valid built-in name, a new DocumentProperty is created, added to the collection and returned. The newly created property is assigned a default value (empty string, zero, false or DateTime.MinValue depending on the type of the built-in property).

  If you request a property that is not present in the document and the name is not recognized as a built-in name, a null is returned.

  Parameters:

  name - The case-insensitive name of the property 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()));
  }

Method Detail

• clear

  public void clear()

  Parameters:

  name - The case-insensitive name of the property.

  Returns:

  True if the property exists in the collection; false otherwise.

  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.

• indexOf

  public int indexOf(java.lang.String name)

  Gets the index of a property by name.

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

  Returns:

  The zero based index. Negative value if not found.

  Example:

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