An <code>AudioDeviceFactory</code> class is responsible for creating
|
||
|
a specific <code>AudioDevice</code> 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.
|
||
|
<p>
|
||
|
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.)
