public abstract class AudioDeviceFactory extends Object
AudioDeviceFactory
class is responsible for creating
a specific AudioDevice
implementation. A factory implementation
can be as simple or complex as desired and may support just one implementation
or may return several implementations depending upon the execution
environment.
When implementing a factory that provides an AudioDevice that uses class that may not be present, the factory should dynamically link to any specific implementation classes required to instantiate or test the audio implementation. This is so that the application as a whole can run without these classes being present. The audio device implementation, however, will usually statically link to the classes required. (See the JavaSound deivce and factory for an example of this.)
