DigSignatureBox

public DigSignatureBox(java.io.RandomAccessFile raf,
                       BoxHolder parent)

Parameters:
parent - parent superbox of this box
Method Detail

readBox

public boolean readBox()
                throws java.io.IOException
Reads the box, putting appropriate information in the RepInfo object. setModule, setBoxHeader, setRepInfo and setDataInputStream must be called before readBox is called. readBox must completely consume the box, so that the next byte to be read by the DataInputStream is the FF byte of the next Box.

Specified by:
