Detailed Description

template<class T>
struct EBGeometry::RayDetail::CrossingPairer< T >

Pairs crossings, in order, into spans: a span from each crossing the ray enters at to the next it leaves at.

Internal helper; not part of the public API. A crossing the ray leaves at before any it enters at closes a span from the start of the interval; a repeated crossing of the same kind (a ray through an edge shared by two faces crosses both) is skipped.

Template Parameters

T	Floating-point precision.

Member Function Documentation

finish()

template<class T >

void EBGeometry::RayDetail::CrossingPairer< T >::finish ( const T  a_t, RaySpansT< T > &  a_spans  )

inlinenoexcept

Close the open span, if any, at an Open end.

Parameters

[in]	a_t	Where it ends.
[in,out]	a_spans	The list.

take()

template<class T >

void EBGeometry::RayDetail::CrossingPairer< T >::take ( const SpanEndT< T > &  a_end, const bool  a_entering, const T  a_t0, RaySpansT< T > &  a_spans  )

inlinenoexcept

Take the next crossing.

Parameters

[in]	a_end	The crossing.
[in]	a_entering	Whether the ray enters there.
[in]	a_t0	Start of the interval.
[in,out]	a_spans	The list.
