Detailed Description

Stereopermutator implementation details.

Function Documentation

bool Scine::Molassembler::Stereopermutators::cycleModelContradictsGraph	(	const std::vector< Utils::ElementType > &	elementTypes,
		const std::vector< double > &	cycleEdgeLengths,
		const std::vector< BaseAtom > &	bases
	)

Checks whether spatially modeling a cycle contradicts the graph.

Parameters

elementTypes	Element types of the cycle, laid out as A, I, J, ..., X, B
cycleEdgeLengths	Edge lengths forming a cyclic polygon, laid out as A-I, I-J, ..., X-B, B-A
bases	Base atoms to check distances to atoms of the cyclic polygon against. Each base is distanceToLeft away from A and distanceToRight away from B

Complexity \(\Theta(N)\)

Returns: If any distances to atoms of the cyclic polygon are shorter than a single bond

bool Scine::Molassembler::Stereopermutators::triangleBondTooClose	(	const double	a,
		const double	b,
		const double	angle,
		const double	bondRadius
	)

Checks whether the far bond in a triangle is too close to the originating atom.

Parameters

a	Bond length to first atom of triangle
b	Bond length to second atom of triangle
angle	Angle between bonds `a` and `b`
bondRadius	Bond radius of the originating atom

Complexity \(\Theta(1)\)

Returns: Whether the altitude of the originating atom in the resulting triangle is shorter or equal to the bond radius
