public static void dump(byte[] data, long offset, java.io.OutputStream stream, int index) throws java.io.IOException, java.lang.ArrayIndexOutOfBoundsException, java.lang.IllegalArgumentException
The offset argument specifies the start offset of the data array within a larger entity like a file or an incoming stream. For example, if the data array contains the third kibibyte of a file, then the offset argument should be set to 2048. The offset value printed at the beginning of each line indicates where in that larger entity the first byte on that line is located.
All bytes between the given index (inclusive) and the end of the data array are dumped.
