Examples of org.lealone.store.Data.checkCapacity()

org.lealone.store.Data.checkCapacity()
Check if there is still enough capacity in the buffer. This method extends the buffer if required. @param plus the number of additional bytes required

                Data buff = rowBuff;
                buff.reset();
                int min = Constants.FILE_BLOCK_SIZE;
                file.readFully(buff.getBytes(), 0, min);
                int len = buff.readInt() * Constants.FILE_BLOCK_SIZE;
                buff.checkCapacity(len);
                if (len - min > 0) {
                    file.readFully(buff.getBytes(), min, len - min);
                }
                while (true) {
                    r = readRow(buff);
