Slab Class Reference

A chunk of time. Every element must reach slab boundaries exactly, no matter how it actually takes time steps to get there. The simulation can only be assumed to have global data available at slab boundaries. More...

Public Member Functions
	Slab () noexcept=default
	Default constructor gives an invalid Slab.
	Slab (double start, double end) noexcept
	Construct a slab running between two times (exactly).
Time	start () const noexcept
Time	end () const noexcept
TimeDelta	duration () const noexcept
Slab	advance () const noexcept
	Create a new slab immediately following this one with the same (up to roundoff) duration.
Slab	retreat () const noexcept
	Create a new slab immediately preceeding this one with the same (up to roundoff) duration.
Slab	advance_towards (const TimeDelta &dt) const noexcept
	Create a slab adjacent to this one in the direction indicated by the argument, as with advance() or retreat().
Slab	with_duration_from_start (double duration) const noexcept
	Create a new slab with the same start time as this one with the given duration (up to roundoff).
Slab	with_duration_to_end (double duration) const noexcept
	Create a new slab with the same end time as this one with the given duration (up to roundoff).
bool	is_followed_by (const Slab &other) const noexcept
	Check if this slab is immediately followed by the other slab.
bool	is_preceeded_by (const Slab &other) const noexcept
	Check if this slab is immediately preceeded by the other slab.
bool	overlaps (const Slab &other) const noexcept
	Check if slabs overlap. Abutting slabs do not overlap.
void	pup (PUP::er &p) noexcept

Static Public Member Functions
static Slab	with_duration_from_start (double start, double duration) noexcept
	Construct a slab with a given start time and duration. The actual duration may differ by roundoff from the supplied value.
static Slab	with_duration_to_end (double end, double duration) noexcept
	Construct a slab with a given end time and duration. The actual duration may differ by roundoff from the supplied value.

Friends
class	Time
class	TimeDelta
bool	operator== (const Slab &a, const Slab &b) noexcept
bool	operator< (const Slab &a, const Slab &b) noexcept
	Slab comparison operators give the time ordering. Overlapping unequal slabs should not be compared (and will trigger an assertion).
bool	operator== (const Time &a, const Time &b) noexcept

Detailed Description

A chunk of time. Every element must reach slab boundaries exactly, no matter how it actually takes time steps to get there. The simulation can only be assumed to have global data available at slab boundaries.
