Examples of java.io.RandomAccessFile.readFully()

java.io.RandomAccessFile.readFully()
Reads bytes from this stream into the byte array buffer. This method will block until buffer.length number of bytes have been read. @param buffer the buffer to read bytes into @throws IOException If a problem occurs reading from this DataInputStream. @see DataOutput#write(byte[]) @see DataOutput#write(byte[],int,int)

        final RandomAccessFile raf = new RandomAccessFile(imageFileName, "r");

            final byte[] data = new byte[length];
            raf.readFully(data);


            File tmpFile = File.createTempFile("jnode", "bin");
            FileOutputStream os = new FileOutputStream(tmpFile);
            os.write(data);
            os.close();
