Overloads:

• #initialize(factory) ⇒ LazyRef

  Parameters:

  • factory (Class, Proc, #call) —

    the factory for the lazy value, which must be shareable

• #initialize(self: nil) { ... } ⇒ LazyRef

  Parameters:

  • self (BasicObject) (defaults to: nil) —

  • computes the value on first access

  Yield Returns:

  • (BasicObject) —
