Entry that is put into caches. It supports expiration time on entries and can compress values to save space in the cache.
Create an entry with internal attributes set. This method is intended to be used by implementations that store cache entries in a native format instead of as serialized Ruby objects.
# File lib/active_support/cache.rb, line 540 def create (raw_value, created_at, options = {}) entry = new(nil) entry.instance_variable_set(:@value, raw_value) entry.instance_variable_set(:@created_at, created_at.to_f) entry.instance_variable_set(:@compressed, !!options[:compressed]) entry.instance_variable_set(:@expires_in, options[:expires_in]) entry end
Create a new cache entry for the specified value. Options supported are :compress, :compress_threshold, and :expires_in.
# File lib/active_support/cache.rb, line 552 def initialize(value, options = {}) @compressed = false @expires_in = options[:expires_in] @expires_in = @expires_in.to_f if @expires_in @created_at = Time.now.to_f if value if should_compress?(value, options) @value = Zlib::Deflate.deflate(Marshal.dump(value)) @compressed = true else @value = value end else @value = nil end end
# File lib/active_support/cache.rb, line 585 def compressed? @compressed end
Check if the entry is expired. The expires_in parameter can override the value set when the entry was created.
# File lib/active_support/cache.rb, line 591 def expired? if @expires_in && @created_at + @expires_in <= Time.now.to_f true else false end end
Seconds since the epoch when the entry will expire.
# File lib/active_support/cache.rb, line 609 def expires_at @expires_in ? @created_at + @expires_in : nil end
Set a new time when the entry will expire.
# File lib/active_support/cache.rb, line 600 def expires_at=(time) if time @expires_in = time.to_f - @created_at else @expires_in = nil end end
Get the raw value. This value may be serialized and compressed.
# File lib/active_support/cache.rb, line 570 def raw_value @value end
