Public Member Functions | |
__init__ (ConnectionManager manager) | |
bool | dataAvailable () |
Returns true if a datagram is available on the queue; call get_data() to extract the datagram. More... | |
bool | getData (Datagram result) |
This flavor of RecentConnectionReader::get_data(), works like the other, except that it only fills a Datagram object, not a NetDatagram object. More... | |
bool | getData (NetDatagram result) |
If a previous call to data_available() returned true, this function will return the datagram that has become available. More... | |
![]() | |
bool | addConnection (Connection connection) |
Adds a new socket to the list of sockets the ConnectionReader will monitor. More... | |
ConnectionManager | getManager () |
Returns a pointer to the ConnectionManager object that serves this ConnectionReader. More... | |
int | getNumThreads () |
Returns the number of threads the ConnectionReader has been created with. More... | |
bool | getRawMode () |
Returns the current setting of the raw mode flag. More... | |
int | getTcpHeaderSize () |
Returns the current setting of TCP header size. More... | |
bool | isConnectionOk (Connection connection) |
Returns true if the indicated connection has been added to the ConnectionReader and is being monitored properly, false if it is not known, or if there was some error condition detected on the connection. More... | |
bool | isPolling () |
Returns true if the reader is a polling reader, i.e. More... | |
poll () | |
Explicitly polls the available sockets to see if any of them have any noise. More... | |
bool | removeConnection (Connection connection) |
Removes a socket from the list of sockets being monitored. More... | |
setRawMode (bool mode) | |
Sets the ConnectionReader into raw mode (or turns off raw mode). More... | |
setTcpHeaderSize (int tcp_header_size) | |
Sets the header size of TCP packets. More... | |
shutdown () | |
Terminates all threads cleanly. More... | |
This flavor of ConnectionReader will read from its sockets and retain only the single most recent datagram for inspection by client code.
It's useful particularly for reading telemetry-type data from UDP sockets where you don't care about getting every last socket, and in fact if the sockets are coming too fast you'd prefer to skip some of them.
This class will always create one thread for itself.
__init__ | ( | ConnectionManager | manager | ) |
bool dataAvailable | ( | ) |
Returns true if a datagram is available on the queue; call get_data() to extract the datagram.
bool getData | ( | Datagram | result | ) |
This flavor of RecentConnectionReader::get_data(), works like the other, except that it only fills a Datagram object, not a NetDatagram object.
This means that the Datagram cannot be queried for its source Connection and/or NetAddress, but it is useful in all other respects.
bool getData | ( | NetDatagram | result | ) |
If a previous call to data_available() returned true, this function will return the datagram that has become available.
The return value is true if a datagram was successfully returned, or false if there was, in fact, no datagram available. (This may happen if there are multiple threads accessing the RecentConnectionReader).
