Class CustomDocumentProperties

java.lang.Object
  extended by DocumentPropertyCollection
      extended by com.aspose.words.CustomDocumentProperties
All Implemented Interfaces:
java.lang.Iterable

public class CustomDocumentProperties 
extends DocumentPropertyCollection

A collection of custom document properties.

Each DocumentProperty object represents a custom property of a container document.

The names of the properties are case-insensitive.

The properties in the collection are sorted alphabetically by name.

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.
// 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:");
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()));
}

getCount

→ inherited from DocumentPropertyCollection
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.
// The document has a fixed list of built-in properties. The user creates all of the custom properties.

}

get

→ inherited from DocumentPropertyCollection
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.
// 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());

for (DocumentProperty customDocumentProperty : doc.getCustomDocumentProperties()) {
    System.out.println(customDocumentProperty.getName());
    System.out.println(MessageFormat.format("\tType:\t{0}", customDocumentProperty.getType()));

}

get

→ inherited from DocumentPropertyCollection
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.

Document doc = new Document();

doc.getCustomDocumentProperties().add("AuthorizationDate", new Date());

removeAt

→ inherited from DocumentPropertyCollection
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());
