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)
