Invoice extends BusinessDocument uses InvoiceTrait
An invoice — the final billing document of the quote → purchase order → invoice cycle, issued once the goods or services have been delivered.
Reuses Schema.org's own Invoice property names (accountId,
billingPeriod, broker, category, confirmationNumber,
paymentDueDate, paymentStatus, provider, referencesOrder,
scheduledPaymentDate) rather than inventing new ones, per this
namespace's Schema.org-first naming rule (see Quote::$validThrough).
Deliberately does NOT share a property trait with Invoice,
even though both classes hydrate through the same
ThingTrait::__construct raw-array path and are
therefore equally subject to the null|array|X typing rule documented on
BusinessDocument. Two of the candidate properties block a
genuinely shared trait:
referencesOrdermust point at this namespace's own PurchaseOrder (the business document actually being invoiced), notorg\schema\Order— the twoInvoiceclasses need incompatible types for the same property name.- The mirror's
broker/category/billingPeriodunions predate thenull|array|Xconvention and lackarray; widening them to fit a shared trait would editorg\schema\Invoice, contradicting this namespace's "mirror stays untouched" rule (see BusinessDocument).
The properties are therefore declared directly here, correctly typed, rather than forcing a partial/asymmetric trait for no real benefit.
$paymentStatus reuses PaymentStatusType and its existing member
classes (PaymentComplete,
PaymentDue, PaymentDeclined, PaymentPastDue,
PaymentAutomaticallyApplied) rather than new constants, following the
one-class-per-member convention of the StatusEnumeration family.

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.

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.
Tags
Return values
array<string|int, mixed> —JSON-LD representation of the object.
withAtContext()
Sets the internal JSON-LD `@context` attribute.
public
withAtContext(string $context) : $this
Useful if you need a custom JSON-LD context.
Parameters
- $context : string
-
Optional JSON-LD context.
Return values
$thiswithAtType()
Sets the internal JSON-LD `@type` attribute.
public
withAtType(string $type) : $this
Allows overriding the default type inferred from the class.
Parameters
- $type : string
-
Optional JSON-LD type
Return values
$thiswithJSONLDMeta()
Initializes both JSON-LD metadata: `@type` and `@context`.
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
- $atContext : string|null = null
-
Optional JSON-LD context
