Scheduler

PHP script providing basic scheduling functionality.

Installation

Install the latest version using composer require riesenia/scheduler

Or add to your composer.json file as a requirement:

{
    "require": {
        "riesenia/scheduler": "~1.0"
    }
}

Usage

Constructor takes two parameters:

• items - array of integers - item IDs
• terms - array of TermInterface

use Riesenia\Scheduler\Scheduler;

$items = [1, 2];
$terms = [$term1, $term2, $term3, $term4];

$scheduler = new Scheduler($items, $terms);

Adding terms and Items

Items and Terms can be also added separately. All added terms have to implement TermInterface.

$scheduler->addItem(3);
$scheduler->addTerm($term5);

TermInterface

Term is defined by its starting and ending date (getFrom() and getTo() methods). Moreover it can be locked to specific item by providing its ID in getLockedId() method.

Scheduling

Calling schedule() method distibutes terms to items correctly. If this is not possible, scheduler throws SchedulerException with the information which terms overlap.

use Riesenia\Scheduler\SchedulerException;

try {
    $scheduler->schedule();

    // get all the terms with reassigned item IDs
    $scheduler->getTerms();
} catch (SchedulerException $e) {
    \var_dump($e->getConflictingTerms());
}
