Member Function Documentation

void nest::hh_psc_alpha::calibrate ( )

privatevirtual

Re-calculate dependent parameters of the node.

This function is called each time a simulation is begun/resumed. It must re-calculate all internal Variables of the node required for spike handling or updating the node.

Implements nest::Node.

References assert(), numerics::e, and nest::Time::get_steps().

double_t nest::hh_psc_alpha::get_potential ( Time const & ) const

Return membrane potential at time t.

potentials_.connect_logging_device(); This function is not thread-safe and should not be used in threaded contexts to access the current membrane potential values.

Parameters

Time	the current network time

double_t nest::hh_psc_alpha::get_y_elem_ ( ) const

inlineprivate

void nest::hh_psc_alpha::handle ( SpikeEvent & e )

virtual

Handle incoming spike events.

Default implementation of event handlers just throws an UnexpectedEvent exception.

Parameters

thrd	Id of the calling thread.
e	Event object.

This handler has to be implemented if a Node should accept spike events.

See also: class SpikeEvent; class UnexpectedEvent

Exceptions

UnexpectedEvent This is the default event to throw.

Reimplemented from nest::Node.

References assert(), nest::Event::get_delay(), nest::SpikeEvent::get_multiplicity(), nest::Event::get_rel_delivery_steps(), and nest::Event::get_weight().

void nest::hh_psc_alpha::handle ( CurrentEvent & e )

virtual

Handler for current events.

See also: handle(thread, SpikeEvent&)

Exceptions

UnexpectedEvent

Reimplemented from nest::Node.

References assert(), nest::names::c, nest::CurrentEvent::get_current(), nest::Event::get_delay(), nest::Event::get_rel_delivery_steps(), nest::Event::get_weight(), and nest::names::w.

void nest::hh_psc_alpha::handle ( DataLoggingRequest & e )

virtual

Handler for universal data logging request.

See also: handle(SpikeEvent&)

Exceptions

UnexpectedEvent

Reimplemented from nest::Node.

port nest::hh_psc_alpha::handles_test_event	(	SpikeEvent &	,
		rport	receptor_type
	)

inlinevirtual

Check if the node can handle a particular event and receptor type.

This function is called upon connection setup by send_test_event().

handles_test_event() function is used to verify that the receiver can handle the event. It can also be used by the receiver to return information to the sender in form of the returned port. The default implementation throws an IllegalConnection exception. Any node class should define handles_test_event() functions for all those event types it can handle.

See Kunkel et al, Front Neuroinform 8:78 (2014), Sec 3.

Note: The semantics of all other handles_test_event() functions is identical.

Exceptions

IllegalConnection

void nest::hh_psc_alpha::init_buffers_ ( )

privatevirtual

Private function to initialize the buffers of a node.

This function, which must be overloaded by all derived classes, provides the implementation for initializing the buffers of a node.

See also: Node::init_buffers()

Implements nest::Node.

References nest::Archiving_Node::clear_history(), numerics::e, nest::Time::get_ms(), nest::Time::get_resolution(), and nest::hh_psc_alpha_dynamics().

void nest::hh_psc_alpha::init_state_ ( const Node & )

privatevirtual

Private function to initialize the state of a node to model defaults.

This function, which must be overloaded by all derived classes, provides the implementation for initializing the state of a node to the model defaults; the state is the set of observable dynamic variables.

Parameters

Reference to model prototype object.

See also: Node::init_state()

Note: To provide a reasonable behavior during the transition to the new scheme, init_state_() has a default implementation calling init_dynamic_state_().

Implements nest::Node.

References S_.

port nest::hh_psc_alpha::send_test_event	(	Node &	receiving_node,
		rport	receptor_type,
		synindex	syn_id,
		bool	dummy_target
	)

inlinevirtual

Send an event to the receiving_node passed as an argument.

Default implementation of check_connection just throws UnexpectedEvent.

This is required during the connection handshaking to test, if the receiving_node can handle the event type and receptor_type sent by the source node.

If dummy_target is true, this indicates that receiving_node is derived from ConnTestDummyNodeBase and used in the first call to send_test_event(). This can be ignored in most cases, but Nodes sending DS*Events to their own event hooks and then *Events to their proper targets must send DS*Events when called with the dummy target, and *Events when called with the real target, see #478.

Reimplemented from nest::Node.

References numerics::e, nest::Node::handles_test_event(), and nest::Event::set_sender().

void nest::hh_psc_alpha::set_potential	(	Time const &	,
		double_t
	)

Define current membrane potential.

This function is thread-safe and should be used in threaded contexts to change the current membrane potential value.

Parameters

Time	the current network time
double_t	new value of the mebrane potential

void nest::hh_psc_alpha::set_status ( const DictionaryDatum & d )

inline

References P_, S_, nest::hh_psc_alpha::Parameters_::set(), nest::hh_psc_alpha::State_::set(), and nest::Archiving_Node::set_status().

void nest::hh_psc_alpha::update	(	Time const &	,
		const long_t	,
		const long_t
	)

privatevirtual

Bring the node from state $t$ to $t+n*dt$.

n->update(T, from, to) performs the update steps beginning at T+from .. T+to-1, ie, emitting events with time stamps T+from+1 .. T+to.

Parameters

Time	network time at beginning of time slice.
long_t	initial step inside time slice
long_t	post-final step inside time slice

Implements nest::Node.

References assert(), nest::Scheduler::get_min_delay(), and nest::Time::get_steps().

Friends And Related Function Documentation

int hh_psc_alpha_dynamics	(	double	,
		const double *	,
		double *	,
		void *
	)

friend

Function computing right-hand side of ODE for GSL solver.

Note: Must be declared here so we can befriend it in class.; Must have C-linkage for passing to GSL. Internally, it is a first-class C++ function, but cannot be a member function because of the C-linkage.; No point in declaring it inline, since it is called through a function pointer.

Parameters

void* Pointer to model neuron instance.
