示例1:
void
nest::mip_generator::event_hook( DSSpikeEvent& e )
{
// note: event_hook() receives a reference of the spike event that
// was originally created in the update function. there we set
// the multiplicty to store the number of mother spikes. the *same*
// reference will be delivered multiple times to the event hook,
// once for every receiver. when calling handle() of the receiver
// above, we need to change the multiplicty to the number of copied
// child process spikes, so afterwards it needs to be reset to correctly
// store the number of mother spikes again during the next call of event_hook().
// reichert
librandom::RngPtr rng = net_->get_rng( get_thread() );
ulong_t n_mother_spikes = e.get_multiplicity();
ulong_t n_spikes = 0;
for ( ulong_t n = 0; n < n_mother_spikes; n++ )
{
if ( rng->drand() < P_.p_copy_ )
n_spikes++;
}
if ( n_spikes > 0 )
{
e.set_multiplicity( n_spikes );
e.get_receiver().handle( e );
}
e.set_multiplicity( n_mother_spikes );
}示例2: kernel
void
nest::poisson_generator::event_hook( DSSpikeEvent& e )
{
librandom::RngPtr rng = kernel().rng_manager.get_rng( get_thread() );
long n_spikes = V_.poisson_dev_.ldev( rng );
if ( n_spikes > 0 ) // we must not send events with multiplicity 0
{
e.set_multiplicity( n_spikes );
e.get_receiver().handle( e );
}
}示例3: assert
void
nest::ppd_sup_generator::event_hook( DSSpikeEvent& e )
{
// get port number
const port prt = e.get_port();
// we handle only one port here, get reference to vector element
assert( 0 <= prt && static_cast< size_t >( prt ) < B_.age_distributions_.size() );
// age_distribution object propagates one time step and returns number of spikes
ulong_t n_spikes =
B_.age_distributions_[ prt ].update( V_.hazard_step_t_, net_->get_rng( get_thread() ) );
if ( n_spikes > 0 ) // we must not send events with multiplicity 0
{
e.set_multiplicity( n_spikes );
e.get_receiver().handle( e );
}
}示例4: assert
void nest::mip_generator::update(Time const & T, const long_t from, const long_t to)
{
assert(to >= 0 && (delay) from < Scheduler::get_min_delay());
assert(from < to);

// generate spikes of mother process for each time slice
