# Ramaze::Struct

### Public Instance Methods

values_at(*keys) click to toggle source

Makes it possible to access the keys directly by their name, not only their index. The original Struct#values_at tries to call to_int on the arguments. in Ruby < 1.9 this would lead to a quite unintuitive IndexError, while in 1.9 it will say outright that it cannot convert Symbol into Integer. I think this is neither useful nor expected, so we extend Struct#values_at to recognize valid members of the Struct passed into the method and return their values in the same order, just like Hash#values_at.

Example:

    Point = Struct.new(:x, :y)
    point = Point.new(15, 10)

    # Old behaviour:
    point.values_at(0, 1)
    # => [15, 10]
    point.values_at(0..1)
    # => [15, 10]
    point.values_at(:y, :x)
    # => IndexError: offset 20697 too large for struct(size:2)

    # Added new behaviour:
    point.values_at(:y, :x)
    # => [10, 15]

    # File lib/ramaze/snippets/ramaze/struct.rb, line 32
    def values_at(*keys)
      keys.map do |key|
        case key
        when String, Symbol
          self[key]
        else
          return super
        end
      end
    end
