Constructor Detail

SeekableInputStream

public SeekableInputStream(long contentLength,
                           long maxSkipDistance)

Parameters:

contentLength - Total stream length

maxSkipDistance - Maximum distance that should be skipped by reading and discarding

Method Detail

getContentLength

public long getContentLength()

Returns:

Length of the stream

getMaxSkipDistance

public long getMaxSkipDistance()

Returns:

Maximum distance that this stream will skip without doing a direct seek on the underlying resource.

getPosition

public abstract long getPosition()

Returns:

Current position in the stream

seekHard

protected abstract void seekHard(long position)
                          throws java.io.IOException

Throws:

java.io.IOException

canSeekHard

public abstract boolean canSeekHard()

Returns:

true if it is possible to seek to an arbitrary position in this stream, even when it is behind the current position.

skipFully

public void skipFully(long distance)
               throws java.io.IOException

Skip the specified number of bytes in the stream. The result is either that the requested number of bytes were skipped or an EOFException was thrown.

Parameters:

distance - The number of bytes to skip

Throws:

java.io.IOException - On IO error

seek

public void seek(long position)
          throws java.io.IOException

Seek to the specified position

Parameters:

position - The position to seek to

Throws:

java.io.IOException - On a read error or if the position is beyond EOF

getTrackInfoProviders

public abstract java.util.List<AudioTrackInfoProvider> getTrackInfoProviders()
