def metaclass
  class << self; self end

#tap {|_self| ... } ⇒ Object

Return this object after yielding it to the block. This is useful for neatly working with an object in some way before returning it:

def valmorphanize
  process.tap {|result|
    log_error "Oops!" unless result
  }
end

Yields:

  • (_self)

Yield Parameters:

  • _self (Object) —

    the object that the method was called on
