Class AudioDeviceFactory
java.lang.Object
javazoom.jl.player.AudioDeviceFactory
public abstract class AudioDeviceFactory
extends java.lang.Object
An
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.)
createAudioDevice
public abstract AudioDevice createAudioDevice()
throws JavaLayerException
Creates a new AudioDevice
.
- a new instance of a specific class of
AudioDevice
.
instantiate
protected AudioDevice instantiate(ClassLoader loader,
String name)
throws ClassNotFoundException,
IllegalAccessException,
InstantiationException
Creates an instance of an AudioDevice implementation.
loader
- The ClassLoader
to use to
load the named class, or null to use the
system class loader.name
- The name of the class to load.
- A newly-created instance of the audio device class.
