Field Documentation

◆ flags

VALUE RBasic::flags

Per-object flags.

Each ruby objects have their own characteristics apart from their classes. For instance whether an object is frozen or not is not controlled by its class. This is where such properties are stored.

enum ruby_fl_type
Note
This is VALUE rather than an enum for alignment purpose. Back in the 1990s there were no such thing like _Alignas in C.

Definition at line 77 of file rbasic.h.

◆ klass

const VALUE RBasic::klass

Class of an object.

Every object has its class. Also, everything is an object in Ruby. This means classes are also objects. Classes have their own classes, classes of classes have their classes, too ... and it recursively continues forever.

Also note the const qualifier. In ruby an object cannot "change" its class.
