Detailed Description

Ruby's ordinal objects.

Unless otherwise special cased, all predefined and user-defined classes share this struct to hold their instances.

Definition at line 93 of file robject.h.

Field Documentation

Embedded instance variables.

When an object is small enough, it uses this area to store the instance variables.

Definition at line 131 of file robject.h.

union { ... } RObject::as

Object's specific fields.

struct RBasic RObject::basic

Basic part, including flags and class.

Definition at line 96 of file robject.h.

struct { ... } RObject::heap

Object that use separated memory region for instance variables use this pattern.

struct st_table* RObject::iv_index_tbl

This is a table that holds instance variable name to index mapping.

Used when accessing instance variables using names.

Definition at line 124 of file robject.h.

VALUE* RObject::ivptr

Pointer to a C array that holds instance variables.

Definition at line 114 of file robject.h.

uint32_t RObject::numiv

Number of instance variables.

This is per object; objects might differ in this field even if they have the identical classes.
