Examples of org.lealone.util.Task

org.lealone.util.Task
A method call that is executed in a separate thread. If the method throws an exception, it is wrapped in a RuntimeException.

            final JdbcConnection c = conn;
            // PipedReader / PipedWriter are a lot slower
            // than PipedInputStream / PipedOutputStream
            // (Sun/Oracle Java 1.6.0_20)
            final PipedInputStream in = new PipedInputStream();
            final Task task = new Task() {
                public void call() {
                    value = c.createClob(IOUtils.getReader(in), -1);
                }
            };
            PipedOutputStream out = new PipedOutputStream(in) {
                public void close() throws IOException {
                    super.close();
                    try {
                        task.get();
                    } catch (Exception e) {
                        throw DbException.convertToIOException(e);
                    }
                }
            };
            task.execute();
            return IOUtils.getBufferedWriter(out);
        } catch (Exception e) {
            throw logAndConvert(e);
        }
