static <T> T	createInstanceMCF(@NonNull XComponentContext context, @NonNull Class<T> type, @NonNull String serviceName) Create an interface object of the given class from the given named service; uses given XComponentContext and 'new' XMultiComponentFactory so only a bridge to office is needed.
static <T> T	createInstanceMSF(@NonNull com.sun.star.lang.XComponent component, @NonNull Class<T> type, @NonNull String serviceName) Create an interface object of the given class from the given named service; uses given XComponent and 'old' XMultiServiceFactory, so a document must have been already loaded/created.
static <T> T	createInstanceMSF(@NonNull com.sun.star.lang.XMultiServiceFactory factory, @NonNull Class<T> type, @NonNull String serviceName) Create an interface object of the given class from the given named service; uses given 'old' XMultiServiceFactory, so a document must have been already loaded/created.
static @NonNull com.sun.star.lang.XMultiServiceFactory	getServiceFactory(@NonNull com.sun.star.lang.XComponent component) Gets the XMultiServiceFactory for the given component.
static <T> T	qi(@NonNull Class<T> type, @NonNull Object object) Queries the given UNO object for the given Java class (which must represent a UNO interface type).
static <T> @NonNull Optional<T>	qiOptional(@NonNull Class<T> type, @NonNull Object object) Queries the given UNO object for the given Java class (which must represent a UNO interface type).

Method Detail

qi

public static <T> T qi(@NonNull Class<T> type,
                       @NonNull Object object)

Queries the given UNO object for the given Java class (which must represent a UNO interface type).

Type Parameters:

T - The requested UNO interface type.

Parameters:

type - A Java class representing a UNO interface type; cannot be null.

object - A reference to any Java object representing (a facet of) a UNO object; cannot be null.

Returns:

A reference to the requested UNO interface type.

UnoRuntime.queryInterface(Class, Object)

qiOptional

public static <T> @NonNull Optional<T> qiOptional(@NonNull Class<T> type,
                                                  @NonNull Object object)

Queries the given UNO object for the given Java class (which must represent a UNO interface type).

Type Parameters:

T - the requested UNO interface type.

Parameters:

type - A Java class representing a UNO interface type; may be null.

object - A reference to any Java object representing (a facet of) a UNO object; may be null.

Returns:

A reference to the requested UNO interface type if available, otherwise null.

getServiceFactory

public static @NonNull com.sun.star.lang.XMultiServiceFactory getServiceFactory(@NonNull com.sun.star.lang.XComponent component)

Gets the XMultiServiceFactory for the given component.

Parameters:

component - The component.

Returns:

The service factory.

createInstanceMSF

public static <T> T createInstanceMSF(@NonNull com.sun.star.lang.XComponent component,
                                      @NonNull Class<T> type,
                                      @NonNull String serviceName)

Create an interface object of the given class from the given named service; uses given XComponent and 'old' XMultiServiceFactory, so a document must have been already loaded/created.

Type Parameters:
