Informations about the package interval
Interval
This library provides some tools to handle intervals. For instance, you can compute the union or intersection of two intervals.
Use cases
- Availabilities calculation.
- Scheduling/calendar/planning.
- Mathematics interval computation with open/closed boundaries
- etc
Features
- It computes some operations between two intervals: union, intersection and exclusion.
- It computes some operations between two sets of intervals: exclusion for now.
- It handles several types of boundaries : float, \DateTime and integer.
- It handles infinity type as boundary.
- Ability to combine infinity with \DateTime and other types.
- filter, sort, map.
- Immutability.
- Chain operations.
Quality
- Code coverage
- Mutation test : Code coverage more than 90%
- Takes care of performance and memory usage
- PSR1/PSR2, Code Smell
Install
composer require kirouane/interval
Basic usage
Let's assume an interval [20, 40]. We instantiate a new Interval object .
or
We can do some operations like :
-
Intersection :
- Union :
or
- Exclusion :
or
We can compare two intervals as well:
-
Overlapping test :
- Inclusion test :
Use DateTimeInterface as boundary
- Union :
Use Infinity as boundary
- Exclusion :
Operations on sets (arrays) of intervals
- Exclusion :
Chaining
Advanced usage
You can create intervals with open boundaries :
