Method Detail

nextBytes

public static void nextBytes(byte[] buffer)

Completely fills the designated buffer with random data generated by the underlying singleton.

Parameters:

buffer - the place holder of random bytes generated by this PRNG singleton. On output, the contents of buffer are replaced with pseudo-random data, iff the buffer size is not zero.

nextBytes

public static void nextBytes(byte[] buffer,
                             int offset,
                             int length)

Fills the designated buffer, starting from byte at position offset with, at most, length bytes of random data generated by the underlying singleton.
