# Usually key value pairs are handled something like this:
|
|
#
|
|
# h = ActiveSupport::OrderedOptions.new
|
|
# h[:boy] = 'John'
|
|
# h[:girl] = 'Mary'
|
|
# h[:boy] # => 'John'
|
|
# h[:girl] # => 'Mary'
|
|
#
|
|
# Using <tt>OrderedOptions</tt> above code could be reduced to:
|
|
#
|
|
# h = ActiveSupport::OrderedOptions.new
|
|
# h.boy = 'John'
|
|
# h.girl = 'Mary'
|
|
# h.boy # => 'John'
|
|
# h.girl # => 'Mary'
