nullreference parameter to methods is incorrect unless explicitly documented on the method as having a meaningful interpretation. Usage to the contrary is incorrect coding and may result in a run time exception either immediately or at some later time.
NullPointerExceptionis an example of typical and acceptable run time exception for such cases.
PackageDescriptionSupplies abstract classes for service providers to subclass when offering new audio devices, sound file readers and writers, or audio format converters.
Clipinterface represents a special kind of data line whose audio data can be loaded prior to playback, instead of being streamed in real time.
DataLineadds media-related functionality to its superinterface,
Lineinterface represents a mono or multi-channel audio feed.Instances of classes that implement the
LineListenerinterface can register to receive events when a line's status changes.A mixer is an audio device with one or more lines.Ports are simple lines for input or output of audio to or from audio devices.A source data line is a data line to which data may be written.A target data line is a type of
DataLinefrom which audio data can be read.
ClassDescriptionAn instance of the
AudioFileFormatclass describes an audio file, including the file type, the file's length in bytes, the length in sample frames of the audio data contained in the file, and the format of the audio data.An instance of the
Typeclass represents one of the standard types of audio file.
AudioFormatis the class that specifies a particular arrangement of data in a sound stream.The
Encodingclass names the specific type of data representation used for an audio stream.An audio input stream is an input stream with a specified audio format and length.The
AudioPermissionclass represents access rights to the audio system resources.The
AudioSystemclass acts as the entry point to the sampled-audio system resources.A
BooleanControlprovides the ability to switch between two possible settings that affect a line's audio.An instance of the
BooleanControl.Typeclass identifies one kind of boolean control.A
CompoundControl, such as a graphic equalizer, provides control over two or more related properties, each of which is itself represented as a
Control.An instance of the
CompoundControl.Typeinner class identifies one kind of compound control.
Linesoften have a set of controls, such as gain and pan, that affect the audio signal passing through the line.An instance of the
Typeclass represents the type of the control.Besides the class information inherited from its superclass,
DataLine.Infoprovides additional information specific to data lines.An
EnumControlprovides control over a set of discrete possible values, each represented by an object.An instance of the
EnumControl.Typeinner class identifies one kind of enumerated control.A
FloatControlobject provides control over a range of floating-point values.An instance of the
FloatControl.Typeinner class identifies one kind of float control.A
Line.Infoobject contains information about a line.The
LineEventclass encapsulates information that a line sends its listeners whenever the line opens, closes, starts, or stops.The LineEvent.Type inner class identifies what kind of event occurred on a line.The
Mixer.Infoclass represents information about an audio mixer, including the product's name, version, and vendor, along with a textual description.The
Line.Infowith additional information specific to ports, including the port's name and whether it is a source or a target for its mixer.The
ReverbTypeclass provides methods for accessing various reverberation settings to be applied to an audio signal.
LineUnavailableExceptionis an exception indicating that a line cannot be opened because it is unavailable.An
UnsupportedAudioFileExceptionis an exception indicating that an operation failed because a file did not contain valid data of a recognized file type and format.
