Обсуждение: PgNotificationHelper
Hello i try to use PgNotificationHelper (http://wiki.postgresql.org/wiki/PgNotificationPoller) , the method:
// not synchronized, must not access pub members
private boolean poll() {
assert(status == Status.LISTENING);
assert(Thread.currentThread().
// not synchronized, must not access pub members
private boolean poll() {
assert(status == Status.LISTENING);
assert(Thread.currentThread().
equals(this));
try {
lastPollTimeMs = System.currentTimeMillis();
helper.poll();
return true;
} catch (SQLException e) {
reportSQLException("Polling for notifications failed, will try to reconnect", e);
return false;
}
}
method poll in class notify.PgNotificationHelper cannot be applied to given types required: java.sql.Connection, long, boolean found: no argument.
i know i need to add the parameters, because the parent class have:
public void poll(Connection conn, long pg_backend_pid, boolean useDummyStatement) throws SQLException {
but, why in PgNotificationHelper don't pass the arguments? is an error?
