Scala synchronized


synchronize on an object

synchronized is a low-level concurrency construct that can help preventing multiple threads access the same resources. Introduction for the JVM using the Java language.

anInstance.synchronized {
 // code to run when the intristic lock on `anInstance` is acquired
 // other thread cannot enter concurrently unless `wait` is called on `anInstance` to suspend
 // other threads can continue of the execution of this thread if they `notify` or
`notifyAll` `anInstance`'s lock

In case of objects it might synchronize on the class of the object, not on the singleton instance.

synchronize implicitly on this

 /* within a class, def, trait or object, but not a constructor */
 synchronized {
 /* code to run when an intrisctic lock on `this` is acquired */
 /* no other thread can get the this lock unless execution is suspended with
 * `wait` on `this`
