Detailed Description

Ruby object's base components.

All Ruby objects have them in common.

Field Documentation

flags

VALUE RBasic::flags

Per-object flags.

Each Ruby object has its own characteristics apart from its class. 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 purposes. Back in the 1990s there were no such thing like _Alignas in C.

Definition at line 81 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.
