Symbol
class Symbol
Symbol
objects represent names and some strings inside the Ruby interpreter. They are generated using the :name
and :"string"
literals syntax, and by the various to_sym
methods. The same Symbol
object will be created for a given name or string for the duration of a program's execution, regardless of the context or meaning of that name. Thus if Fred
is a constant in one context, a method in another, and a class in a third, the Symbol
:Fred
will be the same object in all three contexts.
