Public interface

new/3

Constructs a new interval given start and end points. The start point must strictly precede the end point.

Compilation flags:
static
Template:
new(Start,End,Interval)
Mode and number of proofs:
new(@ground,@ground,-interval) - zero_or_one

valid/1

True if Interval is a valid interval.

Compilation flags:
static
Template:
valid(Interval)
Mode and number of proofs:
valid(@interval) - zero_or_one

before/2

True if Interval1 takes place before Interval2.

Compilation flags:
static
Template:
before(Interval1,Interval2)
Mode and number of proofs:
before(@interval,@interval) - zero_or_one

meets(@interval,@interval) - zero_or_one

met_by/2

True if Interval1 is met by Interval2.

Compilation flags:
static
