Constructor Detail

CuttingInputStream

public CuttingInputStream(java.io.InputStream is,
                          long off,
                          long length)

Creates editing InputStream. Only the data bytes from the given position with the given length of the underlying InputStream are read. (the bytes from 'off' to 'off+length')

Parameters:

is - the underlying (source) InputStream

off - read data starts from this frame position

length - read length frames

CuttingInputStream

public CuttingInputStream(java.io.InputStream is,
                          int frameSize,
                          long off,
                          long length)

Creates editing InputStream. Only the data frames from the given position with the given length of the underlying InputStream are read. (the bytes from 'off * frameSize' to '(off+length) * frameSize')

Parameters:

is - the underlying (source) InputStream

frameSize - size of the data frames

off - read data starts from this frame position

length - read length frames
