Adjustment extends StructuredValue uses AdjustmentTrait

A price adjustment applied on a {@see BusinessDocumentLine} or on a whole {@see BusinessDocument} — inspired by UBL's `AllowanceCharge`.

Covers discounts, surcharges, shipping fees, environmental fees, deposits and packaging, all through the single type property (see PriceComponentType) rather than one boolean/property per kind. Environmental fees are always carried this way — never through a dedicated "eco tax" property — with EcoFeeRule and AppliedEcoFee documenting the rule that produced the amount.

Exactly one of amount or percentage is expected to be set ; when both are absent the adjustment carries no monetary effect (informational only).

An adjustment with a monetary effect may carry the taxes it owes, at a rate of its own : the tax on a shipping fee answers to the carrier, not to the goods.

Constants

CONTEXT

The @context of the json-ld representation of the thing.

public string CONTEXT = \xyz\oihana\schema\constants\Oihana::SCHEMA

JSON_PRIORITY_KEYS

Defines the priority order of keys when serializing the object to JSON-LD.

public array<string|int, mixed> JSON_PRIORITY_KEYS = [\org\schema\constants\Schema::AT_TYPE, \org\schema\constants\Schema::AT_CONTEXT, \org\schema\constants\Schema::_KEY, \org\schema\constants\Schema::_FROM, \org\schema\constants\Schema::_TO, \org\schema\constants\Schema::ID, \org\schema\constants\Schema::NAME, \org\schema\constants\Schema::URL, \org\schema\constants\Schema::CREATED, \org\schema\constants\Schema::MODIFIED]

Keys listed here will always appear first in the serialized array, in the order specified. All remaining public properties will be sorted alphabetically after these priority keys.

This ensures that important JSON-LD metadata and system fields (like @type, @context, _key, id, url, created, modified, etc.) appear at the top of the output for consistency and readability.

Usage:

$orderedKeys = self::JSON_PRIORITY_KEYS;

Notes:

  • Can be overridden in a subclass by redefining the constant.
  • Late static binding (static::JSON_PRIORITY_KEYS) allows child classes to modify the serialization order.

List of JSON-LD keys in priority order.

$description

A short description of the item.

public string|object|array<string|int, mixed>|null $description

$disambiguatingDescription

$subjectOf

A CreativeWork or Event about this Thing.

public null|string|array<string|int, mixed>|CreativeWork|Event $subjectOf

$taxes

The taxes owed on the adjustment itself.

public null|array<string|int, mixed>|TaxDetail $taxes

A charge is rarely tax-free : a shipping fee is taxed at its own rate, which is not necessarily the rate of the goods it delivers. Stating it here — rather than folding it into a document-level total — is what lets a reader tell where each part of the tax came from, and keeps a document whose lines and charges are taxed differently readable line by line.

Same shape as BusinessDocumentLine::$taxes : one TaxDetail per rate, each carrying the basis it applies to and the amount it produces. An adjustment carrying no monetary effect carries no tax either.

Attributes
#[HydrateWith]
\xyz\oihana\schema\business\documents\TaxDetail::class

$url

URL of the item.

public int|string|null $url

$atContext

The JSON-LD `@context` value.

protected string|null $atContext = null

Default is https://schema.org.

$atType

The JSON-LD `@type` value.

protected string|null $atType = null

This can be manually set or automatically inferred from the class name.

$DEFAULT_JSON_SERIALIZE_OPTIONS

protected static array<string|int, mixed> $DEFAULT_JSON_SERIALIZE_OPTIONS = []

$schemaTypeCache

Internal cache for resolved schema types.

private static array<string, string> $schemaTypeCache = []

Methods

__construct()

Constructor to hydrate public properties from an array or stdClass.

public __construct([array<string|int, mixed>|object|null $init = null ]) : mixed

This allows objects to be quickly populated with associative data without manually setting each property.

Parameters
$init : array<string|int, mixed>|object|null = null

A data array or object used to initialize the instance. Keys must match public property names.

Tags
throws
ReflectionException
example
use org\schema\Person;
use org\schema\constants\Prop;

$person = new Person
([
    Prop::NAME => 'Jane Doe',
    Prop::URL  => 'https://example.com/janedoe'
]);

echo $person->name; // Outputs: Jane Doe

getJsonSerializeOptions()

Returns the default JSON serialization options.

public getJsonSerializeOptions() : array<string|int, mixed>

This method determines how the jsonSerialize() output is reduced or compressed, etc. It can be overridden in child classes to customize serialization behavior.

Return values
array<string|int, mixed>

Returns the reduction/compression options for JSON serialization.

getSchemaType()

Returns the fully qualified URI of the schema type.

public static getSchemaType() : string

This method combines the class's CONTEXT constant with its short name to produce a globally unique identifier for the entity type.

  • It uses Late Static Binding to ensure the correct context is retrieved even when called from an inherited class (e.g., Corporation vs. Affiliate).
  • Performance Optimization: Results are stored in a static cache ($schemaTypeCache) to avoid redundant Reflection calls during the same execution lifecycle.
Return values
string

The absolute URI of the type (e.g., "https://schema.org/Thing"). ** @example

echo Thing::getSchemaType();      // https://schema.org/Thing
echo Affiliate::getSchemaType();  // https://schema.oihana.xyz/Pagination

jsonSerialize()

Serializes the current object into a JSON-LD array.

public jsonSerialize() : array<string|int, mixed>

Includes public properties, the JSON-LD @context and @type. Null values are automatically removed.

Tags
throws
ReflectionException

example
use org\schema\Person;
use org\schema\constants\Prop;

$person = new Person
([
    Prop::NAME => 'John Smith',
    Prop::ID   => 'jsmith-001'
]);

echo json_encode($person, JSON_PRETTY_PRINT);

Output:

{
   "@type": "Person",

   "id": "jsmith-001",
   "name": "John Smith"
}
