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");

// A document's built in properties contains a set of predetermined keys
// with values such as the author's name or document's word count
// We can add our own keys and values to a custom properties collection also
// Before we add a custom property, we need to make sure that one with the same name doesn't already exist
Assert.assertEquals("Value of custom document property", doc.getCustomDocumentProperties().get("CustomProperty").toString());

doc.getCustomDocumentProperties().add("CustomProperty2", "Value of custom document property #2");

// Iterate over all the custom document properties
System.out.println("Custom Properties:");
for (DocumentProperty customDocumentProperty : (Iterable<DocumentProperty>) doc.getCustomDocumentProperties()) {
    System.out.println(customDocumentProperty.getName());
    System.out.println("\tType:\t{customDocumentProperty.Type}");
    System.out.println("\tValue:\t\"{customDocumentProperty.Value}\"");
}

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");

// A document's built in properties contains a set of predetermined keys
// with values such as the author's name or document's word count
// We can add our own keys and values to a custom properties collection also
// Before we add a custom property, we need to make sure that one with the same name doesn't already exist
Assert.assertEquals("Value of custom document property", doc.getCustomDocumentProperties().get("CustomProperty").toString());

doc.getCustomDocumentProperties().add("CustomProperty2", "Value of custom document property #2");

// Iterate over all the custom document properties
System.out.println("Custom Properties:");
for (DocumentProperty customDocumentProperty : (Iterable<DocumentProperty>) doc.getCustomDocumentProperties()) {
    System.out.println(customDocumentProperty.getName());
    System.out.println("\tType:\t{customDocumentProperty.Type}");
    System.out.println("\tValue:\t\"{customDocumentProperty.Value}\"");
}

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 with the value of a date and time.

Document doc = new Document();

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

System.out.println("Document authorized on {doc.CustomDocumentProperties[");

public void clear()

Removes all properties from the collection.

Example:

Shows how to add custom properties to a document.

Document doc = new Document();
