Modules, Services and Interfaces 68 In addition to the module and service terms, UNO introduces the term 'interface'. While this term may be familiar to Java programmers, it is not used in Basic. An interface combines several methods. In the strictest sense of the word, a service in UNO does not support methods, but rather interfaces, which in turn provide different methods. In other words, the methods are assigned (as combinations) to the service in interfaces. This detail may be of interest in particular to Java- or C++ programmers, since in these languages, the interface is needed to request a method. In OpenOffice.org Basic, this is irrelevant. Here, the methods are called directly by means of the relevant object. For an understanding of the API, it is, however, useful to have the assignment of methods to various interfaces handy, since many interfaces are used in the different services. If you are familiar with an interface, then you can transfer your knowledge from one service to another. Some central interfaces are used so frequently, triggered by different services, that they are shown again at the end of this chapter.

In addition to this guide, you can get more information about objects from the following sources: the supportsService method, the debug methods as well as the Developer's Guide, and the API reference. The supportsService Method A number of UNO objects support the supportsService method, with which you can establish whether an object supports a particular service. The following call, for example, determines whether the TextElement object supports the service. com.sun.star.text.Paragraph Ok = TextElement.supportsService("com.sun.star.text.Paragraph")
Tools for Working with UNO 69 Debug Properties Every UNO object in OpenOffice.org Basic knows what properties, methods and interfaces it already contains. It provides properties that return these in the form of a list. The corresponding properties are: DBG_properties returns a string containing all properties of an object DBG_methods returns a string containing all methods of an object DBG_supportedInterfaces returns a string containing all interfaces which support an object. The following program code shows how DBG_properties and DBG_methods can be used in real-life applications. It first creates the com.sun.star.frame.Desktop service and then displays the supported properties and methods in message boxes. Dim Obj As Object Obj = createUnoService("com.sun.star.frame.Desktop") MsgBox Obj.DBG_Properties MsgBox Obj.DBG_methods When using DBG_properties, note that the function returns all properties that one particular service can theoretically support. No assurances are, however, provided for whether these can also be used by the object in question. Before calling up properties, you must therefore use the IsEmpty function to check whether this is actually available. API Reference More information about the available services, and their interfaces, methods and properties can be found in the reference for the OpenOffice.org API [1] .
