Method: Concurrent::AtomicReference#try_update!

Defined in:
lib/concurrent-ruby/concurrent/atomic/atomic_reference.rb

#try_update! {|Object| ... } ⇒ Object

Note:

This behavior mimics the behavior of the original ‘AtomicReference#try_update` API. The reason this was changed was to avoid raising exceptions (which are inherently slow) by default. For more info: github.com/ruby-concurrency/concurrent-ruby/pull/336

Pass the current value to the given block, replacing it with the block’s result. Raise an exception if the update fails.

Yields:

  • (Object) —

    Calculate a new value for the atomic reference using given (old) value

Yield Parameters:

  • old_value (Object) —

    the starting value of the atomic reference

Returns:

  • (Object) —

    the new value

Raises:
