Module#autoload

(::interned _module, ::String filename) -> ::NilClass

mod.autoload(const, filename) → nil

static VALUE
rb_mod_autoload(VALUE mod, VALUE sym, VALUE file)
{
    ID id = rb_to_id(sym);

    FilePathValue(file);
    rb_autoload_str(mod, id, file);
    return Qnil;
}

Registers filename to be loaded (using Kernel::require) the first time that const (which may be a String or a symbol) is accessed in the namespace of mod.

Example

module A
end
A.autoload(:B, "b")
A::B.doit            # autoloads "b"

If const in mod is defined as autoload, the file name to be loaded is replaced with filename. If const is defined but not as autoload, does nothing.
