Document Code Enum

All document types are defined in the CodigoDocumento enum: 
use libredte\lib\Core\Package\Billing\Component\Document\Enum\CodigoDocumento;

// Access document codes
CodigoDocumento::FACTURA_AFECTA->value; // 33
CodigoDocumento::BOLETA_AFECTA->value; // 39
CodigoDocumento::NOTA_CREDITO->value; // 61
Each document type has its own interface in the Contract\Document namespace, ensuring type safety and clear separation of concerns.

​
Common Properties

All document types share common functionality through the base DocumentInterface:
  • Document code (código)
  • Document name (nombre)
  • Short name (nombre corto)
  • Alias for programmatic access
  • Associated PHP interface

​
Using Document Types

You can retrieve document information using the enum methods: 
$factura = CodigoDocumento::FACTURA_AFECTA;

// Get official SII code
$codigo = $factura->getCodigo(); // 33

// Get full name
$nombre = $factura->getNombre(); // "Factura electrónica"

// Get short name (without "electrónica")
$nombreCorto = $factura->getNombreCorto(); // "Factura"

// Get alias
$alias = $factura->getAlias(); // "factura_afecta"

// Get associated interface
$interface = $factura->getInterface(); // FacturaAfectaInterface::class
