Constructor Details

#initialize(original, *default_args, method: :to_s, &default_block) ⇒ Liquefied

Public: Wrap an object with a default finalizer method

The object remains wrapped and responds to all its original methods until the finalizer method is called. The finalizer method can be set up with default arguments, which are passed if the method is called implicitly or with no options.

object - The original value to wrap

Examples:

Liquefied.new(12.333, method: [:to_s]) { |val| "%.2f" % val }
Liquefied.new(Date.new(2016,1,1), :to_s, :long)
#=> "January 1, 2016"
