Struct

v1_8_7_72 - Show latest stable - Superclass: Object

A Struct is a convenient way to bundle a number of attributes together, using accessor methods, without having to write an explicit class.

The Struct class is a generator of specific classes, each one of which is defined to hold a set of variables and their accessors. In these examples, we’ll call the generated class ``CustomerClass,’‘ and we’ll show an example instance of that class as ``CustomerInst.’‘

In the descriptions that follow, the parameter symbol refers to a symbol, which is either a quoted string or a Symbol (such as :name).

==== Code example

Google = Struct.new(:address) do
def latitude
  -1
end

def longitude
  -2
end

def with_address
  "with #{address}"
end
end

g = Google.new("Some Addres")

puts g.address
puts g.latitude
puts g.longitude
puts g.with_address

==== Result

# >> Some Addres
# >> -1
# >> -2
# >> with Some Addres
