Defined in:
lib/weak/map/strong_secondary_keys.rb

#each_pair {|key, value| ... } ⇒ self, Enumerator

Calls the given block once for each live key in self, passing the key and value as parameters. Returns the weak map itself.

If no block is given, an Enumerator is returned instead.

Yields:

  • (key, value) —

    calls the given block once for each key in self

Yield Parameters:

  • key (Object) —

    the key of the current key-value pair

  • value (Object) —

    the value of the current key-value pair

Returns:

  • (self, Enumerator) —

    self if a block was given or an Enumerator if no block was given.
