Parameters:   file - the underlying file. Parameters:   ra - the randomly-accessible version of the file. Parameters:   blocksize - the block size to use for accessing the file. Method Detail makeDigest byte[] makeDigest(String s)(Code) read public void read(long blockNum, byte[] buf) throws IOException(Code) Read a block into a buffer. If the specified block is beyond the current end of file, then grow the file Parameters:   blockNum - the number of the block to read. Parameters:   buf - the buffer into which the data is read. setKey public void setKey(SymmetricKey key) throws IOException(Code) write public void write(long blockNum, byte[] buf) throws IOException(Code) Write a block from a buffer into the file. Parameters:   blockNum - the number of the block to write. Parameters:   buf - the buffer from which the data is written. exception:   IOException - if an I/O error occurs.
