Member Function Documentation

void LateralLongRangeOrientationConnectionPredicate::init	(	SimObjectPopulation const &	src,
		SimObjectPopulation const &	dst,
		RandomEngine *	rnd
	)			[virtual]

This function will be called to tell the decision predicate about the source and destination poulation.

This is a generic implementation which checks the actual type of the src and dst populations and stores references to the populations in the two protected members m_sourcePopulation and m_destinationPopulation.

Reimplemented from ConnectionDecisionPredicateSpecialization< AugmentedSpatialPopulation, AugmentedSpatialPopulation >.

Definition at line 47 of file LateralLongRangeOrientationConnectionPredicate.cpp.

References ConnectionDecisionPredicateSpecialization< AugmentedSpatialPopulation, AugmentedSpatialPopulation >::init().

Here is the call graph for this function:

bool LateralLongRangeOrientationConnectionPredicate::decide	(	size_t	src,
		size_t	dst,
		RandomEngine *	rnd
	)			[virtual]

Return true if a uniform distributed random number is smaller than C * exp( -|px-py|^2 / lambda^2 ).

Self connections are not made by returning false if ID(src) == ID(dst).
