CreateTypeInstance

CreateTypeInstance[type,arg1,arg2,…]

creates an instance of a type in compiled code.

CreateTypeInstance[productType,field1x1,field2x2,…|>]

creates an instance of a product type and initializes its fields.

Details

  • The arguments in CreateTypeInstance[type,arg1,arg2,…] can vary from type to type and are often documented with the type itself.
  • For many types, CreateTypeInstance[type,arg] creates a copy of arg if arg is an instance of type.
  • Some types that can be instantiated with CreateTypeInstance are not automatically memory managed and must be manually freed with DeleteObject.
