Detailed Description

Correlomatrixdetector class.

Note: Correlomatrix detectors IGNORE any connection delays.; Correlomatrix detector breaks with the persistence scheme as follows: the internal buffers for storing spikes are part of State_, but are initialized by init_buffers_().

Todo:

The correlation detector could be made more efficient as follows (HEP 2008-07-01):

incoming_ is vector of two deques
let handle() push_back() entries in incoming_ and do nothing else
keep index to last "old spike" in each incoming_; cannot be iterator since that may change
update() deletes all entries before now-tau_max, sorts the new entries, then registers new entries in histogram

Member Function Documentation

void nest::correlomatrix_detector::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.

void nest::correlomatrix_detector::get_status ( DictionaryDatum & d ) const

inline

References nest::names::element_type, and nest::names::recorder.

void nest::correlomatrix_detector::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::Scheduler::get_min_delay(), nest::SpikeEvent::get_multiplicity(), nest::Event::get_rport(), nest::Event::get_stamp(), nest::Time::get_steps(), nest::Event::get_weight(), and nest::names::other.

port nest::correlomatrix_detector::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

Reimplemented from nest::Node.

References nest::Node::get_name(), nest::correlomatrix_detector::Parameters_::N_channels_, P_, and nest::names::receptor_type.

bool nest::correlomatrix_detector::has_proxies ( ) const

inlinevirtual

This device has proxies, so that it will receive spikes also from sources which live on other threads.

Reimplemented from nest::Node.

void nest::correlomatrix_detector::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.

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

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 device_, nest::Node::init_state(), and S_.

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

inline

References nest::correlomatrix_detector::Parameters_::set().

void nest::correlomatrix_detector::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.
