dump
public static void dump(byte[] data, long offset, OutputStream stream, int index, int length) throws IOException, ArrayIndexOutOfBoundsException, IllegalArgumentException dump an array of bytes to an OutputStream- Parameters:
data- the byte array to be dumpedoffset- its offset, whatever that might meanstream- the OutputStream to which the data is to be writtenindex- initial index into the byte arraylength- number of characters to output- Throws:
IOException- is thrown if anything goes wrong writing the data to streamArrayIndexOutOfBoundsException- if the index is outside the data array's boundsIllegalArgumentException- if the output stream is null
