Returns the string representation.

| UInt32 heartbeatInterval |
Specifies maximal time interval between two network packets.
If no data is received during specified time frame, corresponding warning is raised.
Interval is measured in seconds.

| UInt32 lostPacketWaitTime |
Indicates for how long Handler should wait for the packet before it's considered as totally lost.
Due to unreliable nature of multicast, data transmitted by MDP may come in order other than original or be completely lost. When Handler receives packet with sequence number greater than expected, it considers received data as out-of-order. If for a certain time interval Handler receives missing data, Handler resumes normal data processing. However, if no data is received for predefined time frame, Handler considers missing data as lost and raises packet gap event. Given parameter defines size of time interval Handler waits for missing data.
Time interval is measured in microseconds (uSec).

| unsigned short maxPacketSize |
Max size for network packet transmitted by Euronext Optiq MDG.
Definition at line 262 of file HandlerSettings.h.
| std::string networkInterface |
Specifies one or more network interfaces to use while joining the multicast group; use semi-colon delimited list if more than one.
On Linux the network interfaces is specified by its name, on Windows - by IP address.
Definition at line 163 of file HandlerSettings.h.
| std::string networkInterfaceA |
Specifies one or more network interfaces to use while joining the multicast group A; use semi-colon delimited list if more than one.
On Linux the network interfaces is specified by its name, on Windows - by IP address.
Definition at line 172 of file HandlerSettings.h.
| std::string networkInterfaceB |
Specifies one or more network interfaces to use while joining the multicast group B; use semi-colon delimited list if more than one.
On Linux the network interfaces is specified by its name, on Windows - by IP address.
Definition at line 181 of file HandlerSettings.h.
| UInt32 outOfOrderPacketMaxInterval |
Defines value of threshold used by Handler to differ out-of-order packets from gaps.
Due to unreliable nature of multicast, packets transmitted by exchange may be received in the order different to original. To differ the case when Handler received out-of-order packets from the case when some of packets were completely lost, Handler uses given parameter. It defines size of interval for incoming packets starting from the last received. Packet is considered as out-of-order if its sequence number fits into interval [seqNumberOfLastReceivedPacket, seqNumberOfLastReceivedPacket + outOfOrderPacketsMaxInterval]. In that case Handler waits for other packets to fulfill the incoming sequence. If received packet has greater sequence number than 'seqNumberOfLastReceivedPacket + outOfOrderPacketsMaxInterval', then Handler makes a decision on packets lost and gap is reported.
