Public Class methods

new()

Create a new thread safe cache.

[show source] 
   # File lib/roda/cache.rb
10 def initialize
11   @mutex = Mutex.new
12   @hash = {}
13 end

Public Instance methods

[](key)

Make getting value from underlying hash thread safe.

[show source] 
   # File lib/roda/cache.rb
16 def [](key)
17   @mutex.synchronize{@hash[key]}
18 end
[]=(key, value)

Make setting value in underlying hash thread safe.

[show source] 
   # File lib/roda/cache.rb
21 def []=(key, value)
22   @mutex.synchronize{@hash[key] = value}
23 end
freeze()

Return the frozen internal hash. The internal hash can then be accessed directly since it is frozen and there are no thread safety issues.

   # File lib/roda/cache.rb
