Class DocumentPropertyCollection

java.lang.Object
    com.aspose.words.DocumentPropertyCollection

All Implemented Interfaces:

java.lang.Iterable

Direct Known Subclasses:

BuiltInDocumentProperties, CustomDocumentProperties

public abstract class DocumentPropertyCollection 
extends java.lang.Object

See Also:

BuiltInDocumentProperties, CustomDocumentProperties

public int getCount()

Gets number of items in the collection.

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()));
}

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:

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()));
}

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:

Retrieves a custom document property by name.

Document doc = new Document(getMyDir() + "Properties.doc");

DocumentProperty prop = doc.getCustomDocumentProperties().get("Authorized Date");

if (prop != null)
{
    System.out.println(prop.toDateTime());
}
else
{
    System.out.println("The document is not authorized. Authorizing...");
    doc.getCustomDocumentProperties().add("AuthorizedDate", new Date());
}

public void clear()

Removes all properties from the collection.

public boolean contains(java.lang.String name)

Returns true if a property with the specified name exists in the collection.

Parameters:

name - The case-insensitive name of the property.

Returns:

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

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.

Parameters:

name - The case-insensitive name of the property.

Returns:

The zero based index. Negative value if not found.

public java.util.Iterator iterator()

Returns an iterator object that can be used to iterate over all items in the collection.

public void remove(java.lang.String name)

Removes a property with the specified name from the collection.

Parameters:

name - The case-insensitive name of the property.

Example:

Removes a custom document property.

Document doc = new Document(getMyDir() + "Properties.doc");

doc.getCustomDocumentProperties().remove("Authorized Date");

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.
