### Public Instance Methods

instance_exec(*args, &block) click to toggle source

@private

based on Bounded Spec InstanceExec (Mauricio Fernandez) eigenclass.org/hiki/bounded+space+instance_exec

- uses singleton_class of matcher instead of global InstanceExecHelper module

- this keeps it scoped to this class only, which is the only place we need it

- only necessary for ruby 1.8.6

    # File lib/rspec/mocks/extensions/instance_exec.rb, line 15
    def instance_exec(*args, &block)
      singleton_class = (class << self; self; end)
      begin
        orig_critical, Thread.critical = Thread.critical, true
        n = 0
        n += 1 while respond_to?(method_name="__instance_exec#{n}")
        singleton_class.module_eval{ define_method(method_name, &block) }
      ensure
        Thread.critical = orig_critical
      end
      begin
        return send(method_name, *args)
      ensure
        singleton_class.module_eval{ remove_method(method_name) } rescue nil
      end
    end
