Method: Weak::Map#clone

Defined in:
lib/weak/map.rb

#clone(freeze: false) ⇒ Weak::Map

Weak::Map objects can't be frozen since this is not enforced by the underlying ObjectSpace::WeakMap implementation. Thus, we try to signal this by not actually setting the frozen? flag and ignoring attempts to freeze us with just a warning.

Parameters:

  • freeze (Bool, nil) (defaults to: false) —

    ignored; we always behave as if this is false. If this is set to a truethy value, we emit a warning.

Returns:

  • (Weak::Map) —

    a new Weak::Map object containing the same elements as self
