Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`void`	`cleanup()` Should close any open streams and remove references to all instantiated objects.
`boolean`	`endOfStream()` Should return false if there is still more data available to be read in.
`AudioFormat`	`getAudioFormat()` Should return the audio format of the data being returned by the read() and readAll() methods.
`boolean`	`initialize(URL url)` Should make any preperations required before reading from the audio stream.
`boolean`	`initialized()` Should return false if the stream is busy initializing.
`SoundBuffer`	`read()` Should read in one stream buffer worth of audio data.
`SoundBuffer`	`readAll()` Should read in all the audio data from the stream (up to the default "maximum file size".
`void`	`reverseByteOrder(boolean b)` Should tell derived classes when they may need to reverse the byte order of the data before returning it in the read() and readAll() methods.

- Method Detail
  - reverseByteOrder
```
void reverseByteOrder(boolean b)
```
    Should tell derived classes when they may need to reverse the byte order of the data before returning it in the read() and readAll() methods. The reason for the reversBytOrder method is because some external codec libraries produce audio data in a format that some external audio libraries require to be reversed. Derivatives of the Library and Source classes for audio libraries which require this type of data to be reversed should call the reverseByteOrder() method for all instances of ICodec that they use. Derivatives of the ICodec interface for codec libraries which which produce this type of data should use the reverseByteOrder() method to know when the data needs to be reversed before returning it in the read() and readAll() methods. If a particular codec library does not produce this type of data, its derived ICodec class may disregard any calls to the reverseByteOrder() method.
    
    Parameters:
    
    b - True if the calling audio library requires byte-reversal by some codec libraries.
  - initialize
```
boolean initialize(URL url)
```
    Should make any preperations required before reading from the audio stream. If another stream is already opened, it should be closed and a new audio stream opened in its place. This method is used internally by SoundSystem not only to initialize a stream, but also to rewind streams and to switch stream sources on the fly.
    
    Returns:
    
    False if an error occurred or if end of stream was reached.
  - initialized
```
boolean initialized()
```
    Should return false if the stream is busy initializing. To prevent bad data from being returned by this method, derived classes should internally synchronize with any elements used by both the initialized() and initialize() methods.
    
    Returns:
    
    True if steam is initialized.
  - read
```
SoundBuffer read()
```
    Should read in one stream buffer worth of audio data. See SoundSystemConfig for more information about accessing and changing default settings.
    
    Returns:
    
    The audio data wrapped into a SoundBuffer context.
  - readAll
```
SoundBuffer readAll()
```
    Should read in all the audio data from the stream (up to the default "maximum file size". See SoundSystemConfig for more information about accessing and changing default settings.
    
    Returns:
    
    the audio data wrapped into a SoundBuffer context.
  - endOfStream
```
boolean endOfStream()
```
    Should return false if there is still more data available to be read in. To prevent bad data from being returned by this method, derived classes should internally synchronize with any elements used in both the endOfStream() and the read() or readAll() methods.
    
    Returns:
    
    True if end of stream was reached.
  - cleanup
```
void cleanup()
```
    Should close any open streams and remove references to all instantiated objects.
  - getAudioFormat
```
AudioFormat getAudioFormat()
```
    Should return the audio format of the data being returned by the read() and readAll() methods.
    
    Returns:
    
    Information wrapped into an AudioFormat context.
