Detailed Description

A class to represent ranges of integers.

Can be unbounded above or below, but they cannot be empty.

Member Function Documentation

everything()

static ConstantInterval Halide::Internal::ConstantInterval::everything ( )

static

The interval representing everything.

single_point()

static ConstantInterval Halide::Internal::ConstantInterval::single_point ( int64_t  x )

static

Construct an interval representing a single point.

bounded_below()

static ConstantInterval Halide::Internal::ConstantInterval::bounded_below ( int64_t  min )

static

Construct intervals bounded above or below.

bounded_above()

static ConstantInterval Halide::Internal::ConstantInterval::bounded_above ( int64_t  max )

static

is_everything()

bool Halide::Internal::ConstantInterval::is_everything

(

)

const

Is the interval the entire range.

is_single_point() [1/2]

bool Halide::Internal::ConstantInterval::is_single_point

(

)

const

Is the interval just a single value (min == max)

is_single_point() [2/2]

bool Halide::Internal::ConstantInterval::is_single_point

(

int64_t

x

)

const

Is the interval a particular single value.

has_upper_bound()

bool Halide::Internal::ConstantInterval::has_upper_bound

(

)

const

Does the interval have a finite least upper bound.

has_lower_bound()

bool Halide::Internal::ConstantInterval::has_lower_bound

(

)

const

Does the interval have a finite greatest lower bound.

is_bounded()

bool Halide::Internal::ConstantInterval::is_bounded

(

)

const

Does the interval have a finite upper and lower bound.

include() [1/2]

void Halide::Internal::ConstantInterval::include

(

const ConstantInterval &

i

)

Expand the interval to include another Interval.

include() [2/2]

void Halide::Internal::ConstantInterval::include

(

int64_t

x

)

Expand the interval to include a point.

make_union()

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

static

Construct the smallest interval containing two intervals.

operator==()

bool Halide::Internal::ConstantInterval::operator==

(

const ConstantInterval &

other

)

const

Equivalent to same_as.

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