Public Instance Methods

exist? (key)

Source

# File lib/rack/cache/entity_store.rb, line 44
def exist?(key)
  @hash.include?(key)
end

Determine whether the response body with the specified key (SHA1) exists in the store.

open (key)

Source

# File lib/rack/cache/entity_store.rb, line 50
def open(key)
  (body = @hash[key]) && body.dup
end

Return an object suitable for use as a Rack response body for the specified key.

purge (key)

Source

# File lib/rack/cache/entity_store.rb, line 69
def purge(key)
  @hash.delete(key)
  nil
end

Remove the body corresponding to key; return nil.

read (key)

Source

# File lib/rack/cache/entity_store.rb, line 56
def read(key)
  (body = @hash[key]) && body.join
end

Read all data associated with the given key and return as a single String.

write (body, ttl=nil)

Source

# File lib/rack/cache/entity_store.rb, line 61
def write(body, ttl=nil)
  buf = []
  key, size = slurp(body) { |part| buf << part }
  @hash[key] = buf
  [key, size]
end

Write the Rack response body immediately and return the SHA1 key.
