# Sass::Util::NormalizedMap

### Public Class Methods

new(map = nil) click to toggle source

Create a normalized map

    # File lib/sass/util/normalized_map.rb, line 12
    def initialize(map = nil)
      @key_strings = {}
      @map = Util.ruby1_8? ? OrderedHash.new : {}

      map.each {|key, value| self[key] = value} if map
    end

### Public Instance Methods

[](k) click to toggle source

@private

    # File lib/sass/util/normalized_map.rb, line 44
    def [](k)
      @map[normalize(k)]
    end

[]=(k, v) click to toggle source

@private

    # File lib/sass/util/normalized_map.rb, line 36
    def []=(k, v)
      normalized = normalize(k)
      @map[normalized] = v
      @key_strings[normalized] = k
      v
    end

as_stored() click to toggle source

@return [Hash] Hash with the keys as they were stored (before normalization).

    # File lib/sass/util/normalized_map.rb, line 61
    def as_stored
      Sass::Util.map_keys(@map) {|k| @key_strings[k]}
    end

delete(k) click to toggle source

@private

    # File lib/sass/util/normalized_map.rb, line 54
    def delete(k)
      normalized = normalize(k)
      @key_strings.delete(normalized)
      @map.delete(normalized)
    end

denormalize(key) click to toggle source

Returns the version of `key` as it was stored before normalization. If `key` isn't in the map, returns it as it was passed in.

@return [String]

    # File lib/sass/util/normalized_map.rb, line 31
    def denormalize(key)
      @key_strings[normalize(key)] || key
    end

      d = super
      d.send(:instance_variable_set, "@map", @map.dup)
      d
    end

    def keys
      @map.keys
    end

map() click to toggle source

    # File lib/sass/util/normalized_map.rb, line 93

      end
      @map.send(method, *args, &block)
    end

normalize(key) click to toggle source

Specifies how to transform the key.

This can be overridden to create other normalization behaviors.

    # File lib/sass/util/normalized_map.rb, line 22
    def normalize(key)
      key.tr("-", "_")
    end

    # File lib/sass/util/normalized_map.rb, line 107
    def update(map)
      map = map.as_stored if map.is_a?(NormalizedMap)

    end
