int SquarePulseSpikeResponse::reset ( double dt ) [virtual]

Called at the beginning of a simulation at t=0.

Reimplemented from FiniteSpikeResponse.

Here is the call graph for this function:

int SquarePulseSpikeResponse::advance ( AdvanceInfo const & ) [virtual]

Calculate the next state and output/propagate the result to succesors/outgoing objects.

The return value of advance contains several bits of information which can be decoded with the bit masks ADVANCEFLAG_* like ADVANCEFLAG_HASSPIKED and ADVANCEFLAG_DEACTIVATE.

Here is the call graph for this function:

int SquarePulseSpikeResponse::spikeHit	(	spikeport_t	port,
		SpikeEvent const &	spike
	)			`[virtual]`

Function to be called if the object is hit by a spike Called by spike exchange mechanims if a spike hits (arrives at) the object A return value of greater 0 indicates that the object is currently not active and the sim engine has to put this object into its list of active spike receivers. A return value of 0 indicates the the object is currently active (i.e. is already in the list of active receviers) and need not to be put into the list of active synapses.
