This class implements a ring buffer for spike delivery. Spikes are scheduled to be delivered at a time t + delay using SpikeBuffer::schedule. All scheduled spikes can then be retrieved by iterating over the list, from first element SpikeIterator::front until SpikeIterator::back.

SpikeBuffer | ( | int | minDelay, |
int | maxDelay | ||
) |
A SpikeBuffer is used to schedule and deliver spikes after a certain delay t + delay. Spikes are scheduled to be delivered at a time t + delay using SpikeBuffer::schedule. All scheduled spikes can then be retrieved by iterating over the list, from first element SpikeIterator::front until SpikeIterator::back.
[in] | minDelay | Minimum delay (in number of time steps) the buffer can handle |
[in] | maxDelay | Maximum delay (in number of time steps) the buffer can handle |

~SpikeBuffer | ( | ) |
The destructor deallocates all scheduled spikes.

void reset | ( | int | minDelay, |

This method resets all allocated data. Must be called at the beginning of a simulation.

This method schedules a spike to be delivered to neuron with ID neurID, after a delay of t + delay time steps.
[in] | neurId | corresponding neuron ID |
[in] | delay | scheduling delay (in number of time steps) |
