Member Function Documentation

bool lar_content::LArHitWidthHelper::ConstituentHit::SortByDistanceToPoint::operator()	(	const ConstituentHit &	lhs,
		const ConstituentHit &	rhs
	)

Sort constituent hits by their position relative to a referencePoint.

Parameters

lhs	first constituent hit
rhs	second constituent hit

Returns

whether lhs hit is closer to the referencePoint than the rhs hit

{
    const CartesianVector &lhsPosition(lhs.GetPositionVector());
    const CartesianVector &rhsPosition(rhs.GetPositionVector());

    return (m_referencePoint.GetDistanceSquared(lhsPosition) < m_referencePoint.GetDistanceSquared(rhsPosition));
}
