Class Method Details

.constructor_wrap(ptr) ⇒ Object

Wraps a pointer retrieved from a constructor method. Here, it is simply defined as a wrapper around direct_wrap, but, e.g., InitiallyUnowned overrides it to sink the floating object.

Unlike wrap, this method assumes the pointer will always be of the type corresponding to the current class, and never of a subtype.

Parameters:

  • ptr —

    Pointer to the object’s C structure

Returns:

  • An object of the current class wrapping the pointer
