Public Class Methods

_load(repr) click to toggle source

@private

# File lib/sass/cache_stores/memory.rb, line 18
def self._load(repr)
  Memory.new
end
new() click to toggle source

Create a new, empty cache store.

# File lib/sass/cache_stores/memory.rb, line 23
def initialize
  @contents = {}
end

Public Instance Methods

_dump(depth) click to toggle source

Since the {Memory} store is stored in the Sass tree's options hash, when the options get serialized as part of serializing the tree, you get crazy exponential growth in the size of the cached objects unless you don't dump the cache.

@private

# File lib/sass/cache_stores/memory.rb, line 11
def _dump(depth)
  ""
end
reset!() click to toggle source

Destructively clear the cache.

# File lib/sass/cache_stores/memory.rb, line 42
def reset!
  @contents = {}
end
retrieve(key, sha) click to toggle source

@see Sass::CacheStores::Base#retrieve

# File lib/sass/cache_stores/memory.rb, line 28
def retrieve(key, sha)
  if @contents.has_key?(key)
    return unless @contents[key][:sha] == sha
    obj = @contents[key][:obj]
    obj.respond_to?(:deep_copy) ? obj.deep_copy : obj.dup
  end
end
store(key, sha, obj) click to toggle source

@see Sass::CacheStores::Base#store

# File lib/sass/cache_stores/memory.rb, line 37
def store(key, sha, obj)
  @contents[key] = {:sha => sha, :obj => obj}
