Create a new Coordinated object and increment the number of members by one.
Create a new Coordinated object and increment the number of members by one. Use this method to pass on the coordination.

Delimits the coordinated transaction. The transaction will wait for all other transactions
in this coordination before committing. The timeout is specified when creating the Coordinated.

Create a new Coordinated object but *do not* increment the number of members by one.
Create a new Coordinated object but *do not* increment the number of members by one. Only use this method if you know this is what you need.
Coordinatedis a message wrapper that adds aCommitBarrierfor explicitly coordinating transactions across actors or threads.Creating a
Coordinatedwill create a commit barrier with initially one member. For each member in the coordination set a transaction is expected to be created using the coordinated atomic method, or the coordination cancelled using the cancel method.The number of included members must match the number of transactions, otherwise a successful transaction cannot be coordinated.
To start a new coordinated transaction set that you will also participate in just create a
Coordinatedobject:val coordinated = Coordinated()To start a coordinated transaction that you won't participate in yourself you can create a
Coordinatedobject with a message and send it directly to an actor. The recipient of the message will be the first member of the coordination set:To receive a coordinated message in an actor simply match it in a case statement:
To include another actor in the same coordinated transaction set that you've created or received, use the apply method on that object. This will increment the number of parties involved by one and create a new
Coordinatedobject to be sent.To enter the coordinated transaction use the atomic method of the coordinated object:
coordinated.atomic { implicit txn => // do something in transaction ... }The coordinated transaction will wait for the other transactions before committing. If any of the coordinated transactions fail then they all fail.
