Module: Lutaml::Xml::Schema::BuiltinTypes

Defined in:
lib/lutaml/xml/schema/builtin_types.rb

Overview

W3C XML Schema 1.1 Part 2: Datatypes www.w3.org/TR/xmlschema11-2/

This module defines all built-in XSD types for validation purposes. Used by XSD generation and validation to identify standard W3C types.

Class Method Summary collapse

Class Method Details

.builtin?(type_name) ⇒ Boolean

Check if a type name is a W3C XML Schema built-in type

Examples:

BuiltinTypes.builtin?("xs:string")  #=> true
BuiltinTypes.builtin?("xs:integer") #=> true
BuiltinTypes.builtin?("CustomType") #=> false

Parameters:

  • type_name (String) —

    The XSD type name to check (e.g., “xs:string”)

Returns:

  • (Boolean) —

    true if the type is a standard W3C built-in type

def self.builtin?(type_name)
  ALL_TYPES.include?(type_name)
end

.category(type_name) ⇒ Symbol?

Get the category of a built-in type

Examples:

BuiltinTypes.category("xs:string")  #=> :primitive
BuiltinTypes.category("xs:integer") #=> :derived
BuiltinTypes.category("CustomType") #=> nil

Parameters:

  • type_name (String) —

    The XSD type name

Returns:

  • (Symbol, nil) —

    :primitive, :derived, :special, or nil if not built-in
