Constructor & Destructor Documentation

◆ RBasic()

RBasic::RBasic ( )

inline

We need to define this explicit constructor because the field klass is const-qualified above, which effectively defines the implicit default constructor as "deleted" (as of C++11) – No way but to define one by ourselves.

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.

See also: 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 75 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.
