Hash#compare_by_identity() es un método de clase Hash que compara la clave hash con su identidad y considera exactamente los mismos objetos que las mismas claves.
Sintaxis: Hash.compare_by_identity()
Parámetro: array hash
Retorno: compara la clave hash con su identidad
Ejemplo 1 :
# Ruby code for compare_by_identity () method
# declaring Hash value
a = {a:100, b:nil}
# declaring Hash value
b = {a:100, c:nil, b:"b"}
# declaring Hash value
c = {a:100}
puts "compare_by_identity a : #{a.compare_by_identity}\n\n"
puts "compare_by_identity b : #{b.compare_by_identity}\n\n"
puts "compare_by_identity b : #{c.compare_by_identity}\n\n"
Producción :
compare_by_identity a : {:a=>100, :b=>nil}
compare_by_identity b : {:a=>100, :c=>nil, :b=>"b"}
compare_by_identity b : {:a=>100}
Ejemplo #2:
# Ruby code for compare_by_identity () method
# declaring Hash value
a = { "a" => 100, "b" => 200 }
# declaring Hash value
b = {"a" => 100}
# declaring Hash value
c = {"a" => 100, "c" => "c", "b" => 200}
puts "compare_by_identity a : #{a.compare_by_identity}\n\n"
puts "compare_by_identity b : #{b.compare_by_identity}\n\n"
puts "compare_by_identity b : #{c.compare_by_identity}\n\n"
Producción :
compare_by_identity a : {"a"=>100, "b"=>200}
compare_by_identity b : {"a"=>100}
compare_by_identity b : {"a"=>100, "c"=>"c", "b"=>200}
