class Module

Extend module with the additional accessor utility.

Public Instance Methods

attr_combined_accessor(*syms) click to toggle source

Creates a combined accessor that allows getting and setting from the same endpoint. It will operate in getter mode if you don't pass any arguments when calling it, otherwise it will work in setter mode. The setter mode returns self. This is really super useful when needing to chain methods (you can't chain standard attr_writer methods because of the `= something` part) or when trying to create a nice looking DSL.

We also create the usual writer though so you can use both.

# File lib/attr_combined_accessor.rb, line 13
def attr_combined_accessor(*syms)
  syms.each do |sym|
    add_attr_combined_accessor(sym)
    attr_writer(sym)
  end
end

# File lib/attr_combined_accessor.rb, line 22
def add_attr_combined_accessor(sym)
  define_method(sym) do |*args|
    if args.empty?
      instance_variable_get(:"@#{sym}")
    else
      instance_variable_set(:"@#{sym}", *args)
      self
    end
  end
end
