cast_to_float(*attributes) click to toggle source

Same as attr_accessor but will always convert to Float internally

# File lib/tracksperanto/casts.rb, line 9
def cast_to_float(*attributes)
  attributes.each do | an_attr |
    define_method(an_attr) { instance_variable_get("@#{an_attr}").to_f }
    define_method("#{an_attr}=") { |to| instance_variable_set("@#{an_attr}", to.to_f) }
  end
end
cast_to_int(*attributes) click to toggle source

Same as attr_accessor but will always convert to Integer/Bignum internally

# File lib/tracksperanto/casts.rb, line 17
def cast_to_int(*attributes)
  attributes.each do | an_attr |
    define_method(an_attr) { instance_variable_get("@#{an_attr}").to_i }
    define_method("#{an_attr}=") { |to| instance_variable_set("@#{an_attr}", to.to_i) }
  end
end
cast_to_string(*attributes) click to toggle source

Same as attr_accessor but will always convert to String internally

# File lib/tracksperanto/casts.rb, line 25
