BusinessDocumentLine extends StructuredValue uses BusinessDocumentLineTrait, HasColor, HasPhysicalMeasures
A single line of a {@see BusinessDocument} : the item sold, its quantity and price, the taxes and adjustments applying to it, and the resulting line totals.
taxes and adjustments are scoped to this line — a document can mix
lines taxed at different rates, or carry a line-specific discount,
independently of the document-level DocumentTotals.

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.

Why the goods on this line leave without being invoiced — a gift, a breakage, a sample, goods that were the customer's to begin with.

DefinedTerm|array<string|int, mixed>|null
$freeReason
= null
🔑 Its presence is what says the line is offered. There is deliberately no boolean beside it : an ERP carrying both a flag and a reason has been observed with the two drifting apart, and a line claiming to be a gift while still charging money is the one thing this property exists to prevent.
The term is frozen by its code and its label (id + name), never by its
storage key : a controlled vocabulary re-harvested into a fresh collection
is renumbered, and a line pointing at a key would silently designate
another term.

$includedInTotal
Whether this line counts towards the document totals.
public
bool|null
$includedInTotal
= null
🔑 Its absence means the line counts. Only a line left out says so, which keeps every document written before this property existed exactly as true as it was.
A priced line is not always a line to pay for. A quote may offer the same work twice — two floorings, two finishes — and expect the customer to keep one : both are printed, both are costed, one is billed. The lines of the discarded option are ordinary lines, with an item, a quantity and a price ; nothing about their content sets them apart. Summing them anyway has been measured to overstate a real quote by a factor of two.
The same slot serves anything shown but not owed — an informational fee, a figure quoted for reference.
⚠️ Do not read it as « this line is a variant » : the reason a line is left out is not its business, only the fact is.

$quantityOrigin
Where the quantity above comes from — worked out by the system, or typed by someone ({@see QuantityOrigin}).
public
string|QuantityOrigin|null
$quantityOrigin
= null
A line written as the consequence of another — a treatment that comes
with the timber, a service an article carries — holds a quantity nobody
typed : it is worked out from the line it serves, and the two are bound.
Four boards of 0.019 cubic metres each make 0.076 cubic metres of
treatment, and nothing else.
🚨 Two rules are right, and they exclude each other. A bound quantity
that stops following under-bills in silence — raise the boards to a hundred
and the treatment stays at 0.076, twenty-five times short of the work that
will be done, with nothing on screen to say so. A typed quantity that gets
overwritten erases a decision just as quietly : whoever typed it had
measured, or agreed a lump sum.
The line therefore has to remember which of the two it is under, and this is
where it does. It is born CALCULATED and turns ENTERED on the first
figure typed into it ; it does not come back on its own.
⚠️ An absent value states nothing, and must not be read as ENTERED : a
line written before the property existed says nothing about where its number
came from.
🔑 This says where the number came from, never what it is bound to. The
line it follows — when it follows one — is named by the inherited isPartOf,
and the two answer different questions : one is a provenance, the other a
relation.

$section
The heading this line belongs to, when the document is written in chapters — « roof frame », « oak flooring », « laying ».
public
string|null
$section
= null
A plain label, repeated on every line of the same group, and deliberately nothing more : no section class, no nesting, no subtotal of its own. The grouping is whatever shares the label, which is enough to print a document in chapters and cheap enough to be worth carrying even when nothing reads it yet.
🚨 Never store the group's subtotal here or beside it. A recap amount living next to the lines it recaps is the shortest path to counting the same goods twice — it is derived, and it stays derived.
Distinct from the inherited description, which names the item itself :
a description belongs to one line, a heading is shared by several.

The twin of HasPhysicalMeasures::$weight, and read the same way : a

is stated ({ value: 1.403, unitCode: "MTQ" }) ; an array is hydrated as
the latter and sits there until it is.
On a line, the quantity multiplied by what the unit it is counted in occupies. Summed over the lines, it gives the document's own volume.

$weight
On a line, the quantity multiplied by what the unit it is counted in weighs. Summed over the lines, it gives the document's own weight.
A plain number carries it when the unit is implicit, a
QuantitativeValue when the unit is stated
({ value: 537.6, unitCode: "KGM" }) ; an array is hydrated as the
latter. The same union as
BusinessDocument::$weight, so
a weight reads the same wherever it is met.
Deliberately neutral about gross and net. Should the distinction ever be
needed, it belongs to the additionalType of a QuantitativeValue, never
to a second property — two weights held in parallel eventually disagree.

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
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.

public
withJSONLDMeta([string|null $atType = null ][, string|null $atContext = null ]) : $this
Can be called from constructor or later to override default values.
Parameters
- $atType : string|null = null
-
Optional JSON-LD type
