C# Класс javazoom.jl.decoder.Bitstream

The Bistream class is responsible for parsing an MPEG audio bitstream. * REVIEW: much of the parsing currently occurs in the various decoders. This should be moved into this class and associated inner classes.

Открытые методы

Метод	Описание
close ( ) : void
closeFrame ( ) : void
get_bits ( int number_of_bits ) : int	Read bits from buffer into the lower bits of an unsigned int. The LSB contains the latest read bit of the stream. (1 <= number_of_bits <= 16)
isSyncCurrentPosition ( int syncmode ) : bool	Determines if the next 4 bytes of the stream represent a frame header.
isSyncMark ( int headerstring, int syncmode, int word ) : bool
readBits ( int n ) : int
readCheckedBits ( int n ) : int
unreadFrame ( ) : void	Unreads the bytes read from the frame. @throws BitstreamException

Приватные методы

Метод	Описание
Bitstream ( BackStream in_Renamed ) : System	Construct a IBitstream that reads data from a given InputStream. *
InitBlock ( ) : void
nextFrame ( ) : void	*
parse_frame ( ) : void	Parses the data previously read with read_frame_data().
readBytes ( sbyte b, int offs, int len ) : int	Simlar to readFully, but doesn't throw exception when EOF is reached.
readFrame ( ) : Header	Reads and parses the next frame from the input source.
readFully ( sbyte b, int offs, int len ) : void	Reads the exact number of bytes from the source input stream into a byte array. *
readNextFrame ( ) : Header
read_frame_data ( int bytesize ) : void	Reads the data for the next frame. The frame is not parsed until parse frame is called.
set_syncword ( int syncword0 ) : void	Set the word we want to sync the header to. In Big-Endian byte order
syncHeader ( sbyte syncmode ) : int	Get next 32 bits from bitstream. They are stored in the headerstring. syncmod allows Synchro flag ID The returned value is False at the end of stream.
