public abstract class DocumentPropertyCollection implements Iterable
Base class for BuiltInDocumentProperties and CustomDocumentProperties collections.
To learn more, visit the Work with Document Properties documentation article.
Remarks:
The names of the properties are case-insensitive.
The properties in the collection are sorted alphabetically by name.
Examples:
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 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());

get(int index)
public DocumentProperty get(int index)
Returns a DocumentProperty object by index.
Remarks:
Note: In Java this method is slow because iterates over all nodes.
Examples:
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.
// The document has a fixed list of built-in properties. The user creates all of the 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:");

System.out.println(MessageFormat.format("\tType:\t{0}", customDocumentProperty.getType()));
System.out.println(MessageFormat.format("\tValue:\t\"{0}\"", customDocumentProperty.getValue()));
}
Parameters:
| Parameter | Type | Description |
|---|---|---|
| index | int | Zero-based index of the DocumentProperty to retrieve. |
Returns: DocumentProperty - A DocumentProperty object by index.
get(String name)
public DocumentProperty get(String name)
Provides access to the collection items. Returns a DocumentProperty object by the name of the property.
Remarks:
Returns null if a property with the specified name is not found.
Examples:
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(MessageFormat.format("Document authorized on {0}", doc.getCustomDocumentProperties().get("AuthorizationDate")));
Parameters:
