    extended by com.aspose.words.DocumentProperty
All Implemented Interfaces:
java.lang.Cloneable

public class DocumentProperty 
extends java.lang.Object

Represents a custom or built-in document property.

Example:

Enumerates through all built-in and custom properties in a document using indexed access.
String fileName = getMyDir() + "Properties.doc";
Document doc = new Document(fileName);

System.out.println(MessageFormat.format("1. Document name: {0}", fileName));

System.out.println("2. Built-in Properties");
for (int i = 0; i < doc.getBuiltInDocumentProperties().getCount(); i++)
{
    DocumentProperty prop = doc.getBuiltInDocumentProperties().get(i);
    System.out.println(MessageFormat.format("{0}({1}) : {2}", prop.getName(), prop.getType(), prop.getValue()));
}

System.out.println("3. Custom Properties");
for (int i = 0; i < doc.getCustomDocumentProperties().getCount(); i++)
{
    DocumentProperty prop = doc.getCustomDocumentProperties().get(i);
    System.out.println(MessageFormat.format("{0}({1}) : {2}", prop.getName(), prop.getType(), prop.getValue()));
}

Converts a boolean property into "Y" or "N". Converts a date property into a short date string. For all other types converts a property using Object.ToString().

Example:

Retrieves the types and values of the custom document properties.
Document doc = new Document(getMyDir() + "Properties.doc");

for (DocumentProperty prop : doc.getCustomDocumentProperties())
{
    System.out.println(prop.getName());
    switch (prop.getType())
    {
        case PropertyType.STRING:

            System.out.println(prop.toString());
            break;
        case PropertyType.BOOLEAN:
            System.out.println("It's a boolean value.");
            System.out.println(prop.toBool());
            break;
        case PropertyType.NUMBER:
            System.out.println("It's an integer value.");
            System.out.println(prop.toInt());
            break;
        case PropertyType.DATE_TIME:
            System.out.println("It's a date time value.");
            System.out.println(prop.toDateTime());
            break;
        case PropertyType.DOUBLE:
            System.out.println("It's a double value.");
            System.out.println(prop.toDouble());
            break;
        case PropertyType.OTHER:
            System.out.println("Other value.");
            break;
        default:
            throw new Exception("Unknown property type.");
    }
}

Example:

Retrieves a built-in document property by name.
Document doc = new Document(getMyDir() + "Properties.doc");

DocumentProperty prop = doc.getBuiltInDocumentProperties().get("Keywords");
