Detailed Description

Sends spikes out to external device using UDP synchronized method Does not technically operate as a server, but called such because it is a provider of spikes to the external device, rather than a receiver.

bool UDPSynchronizedServer::closeDevice (   )

Closes the socket. Definition at line 67 of file UDPSynchronizedServer.cpp. References socketHandle, and socketOpen. Referenced by DeviceManager::closeDevice(), and ~UDPSynchronizedServer().

bool UDPSynchronizedServer::openSocket (  string  address, int  port )

Opens the UDP socket. Adapted from: http://ntrg.cs.tcd.ie/undergrad/4ba2/multicast/antony/index.html. Definition at line 76 of file UDPSynchronizedServer.cpp. References socketAddress, socketHandle, socketOpen, and SpikeStreamSimulation::systemError(). Referenced by DeviceManager::loadDeviceInformation().

UDPSynchronizedServer UDPSynchronizedServer::operator= (  const UDPSynchronizedServer &   )  [private]

Declare assignment private so it cannot be used.

bool UDPSynchronizedServer::sendSpikeData (   )

Sends spike data to the receiving socket. Definition at line 97 of file UDPSynchronizedServer.cpp. References SimulationClock::getTimeStep(), neuronGrpWidth, neuronVectorPtr, SpikeStreamSimulation::simulationClock, simulationSynchronizationDelay(), socketAddress, socketHandle, socketOpen, startNeuronID, STEP_COUNTER_MAX, and SpikeStreamSimulation::systemError().

void UDPSynchronizedServer::setNeuronVector (  vector< unsigned int > *  neurVectPtr, unsigned int  startNeurID )

Passes a reference to the neuron vector in SpikeStreamSimulation to this class. This contains the ids of the currently firing neurons. Definition at line 179 of file UDPSynchronizedServer.cpp. References neuronVectorPtr, and startNeuronID. Referenced by DeviceManager::setNeuronVector().

bool UDPSynchronizedServer::simulationSynchronizationDelay (   )  [private]

Returns true if there is 1 or more entries in the synchronization delay database These entries indicate that another task is delaying itself to synchronize up with an external device. Definition at line 188 of file UDPSynchronizedServer.cpp. References deviceDBInterface, and SpikeStreamSimulation::systemError(). Referenced by sendSpikeData().
