each_pair

struct.each_pair {|sym, obj| block } â struct
struct.each_pair â an_enumerator

Instance Public methods

Calls block once for each instance variable, passing the name (as a symbol) and the value as parameters.

If no block is given, an enumerator is returned instead.

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.each_pair {|name, value| puts("#{name} => #{value}") }

produces:

name => Joe Smith
address => 123 Maple, Anytown NC
zip => 12345
