Detailed Description

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.

Constructor & Destructor Documentation

◆ SpikeBuffer()

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.

Parameters
[in]minDelayMinimum delay (in number of time steps) the buffer can handle
[in]maxDelayMaximum delay (in number of time steps) the buffer can handle

Definition at line 214 of file spike_buffer.cpp.

◆ ~SpikeBuffer()

The destructor deallocates all scheduled spikes.

◆ front()

SpikeBuffer::SpikeIterator front ( int  stepOffset = 0)

◆ length()

size_t length ( )

Definition at line 222 of file spike_buffer.cpp.

◆ reset()

void reset ( int  minDelay,
int  maxDelay 
)

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

Parameters
[in]minDelayMinimum delay (in number of time steps) the buffer can handle
[in]maxDelayMaximum delay (in number of time steps) the buffer can handle

Definition at line 221 of file spike_buffer.cpp.

◆ schedule()

void schedule ( int  neurId,
int  grpId,
unsigned short int  delay 
)

This method schedules a spike to be delivered to neuron with ID neurID, after a delay of t + delay time steps.

Parameters
[in]neurIdcorresponding neuron ID
[in]delayscheduling delay (in number of time steps)
