Method: ClassyEnum::ClassMethods#enum_classes

Defined in:
lib/classy_enum/class_methods.rb

#enum_classes(*enums) ⇒ Object

Macro for defining enum members within a ClassyEnum class. Accepts an array of symbols or strings which are converted to ClassyEnum members as descents of their parent class.

Example

# Define an enum called Priority with three child classes
class Priority < ClassyEnum::Base
  enum_classes :low, :medium, :high
end

The child classes will be defined with the following constants:
PriorityLow, PriorityMedium, and PriorityHigh

These child classes can be instantiated with either:
Priority.build(:low) or PriorityLow.new
