◆ is_single_point() [2/2]

bool Halide::Internal::Interval::is_single_point ( const Expr & e ) const

Is the interval a particular single value.

◆ has_upper_bound()

bool Halide::Internal::Interval::has_upper_bound ( ) const

Does the interval have a finite least upper bound.

◆ has_lower_bound()

bool Halide::Internal::Interval::has_lower_bound ( ) const

Expand the interval to include another Interval.

◆ include() [2/2]

void Halide::Internal::Interval::include ( const Expr & e )

Expand the interval to include an Expr.

◆ make_union()

static Interval Halide::Internal::Interval::make_union	(	const Interval &	a,
		const Interval &	b
	)

static

Construct the smallest interval containing two intervals.

◆ make_intersection()

	)

static

An eagerly-simplifying min of two Exprs that respects infinities.

◆ operator==()

bool Halide::Internal::Interval::operator== ( const Interval & other ) const

Equivalent to same_as.

Exists so that the autoscheduler can compare two map<string, Interval> for equality in order to cache computations.
