Package-level declarations

An Int value that is always updated atomically. For additional details about atomicity guarantees for reads and writes see kotlin.concurrent.Volatile.

A Long value that is always updated atomically. For additional details about atomicity guarantees for reads and writes see kotlin.concurrent.Volatile.

A kotlinx.cinterop.NativePtr value that is always updated atomically. For additional details about atomicity guarantees for reads and writes see kotlin.concurrent.Volatile.

An object reference that is always updated atomically.

Detached object graph encapsulates transferrable detached subgraph which cannot be accessed externally, until it is attached with the attach extension function.

This class was useful only with legacy memory manager. Please use AtomicReference instead.

Exception thrown whenever freezing is not possible.

Class representing abstract computation, whose result may become available in the future.

State of the future object.

Exception thrown whenever we attempt to mutate frozen objects.

Mutable concurrently accessible data buffer. Could be accessed from several workers simultaneously.

Marks all Worker-related API as obsolete.

Marks a top level property with a backing field or an object as thread local. The object remains mutable and it is possible to change its state, but every thread will have a distinct copy of this object, so changes in one thread are not reflected in another.

Note: modern Kotlin/Native memory manager allows to share objects between threads without additional ceremonies, so TransferMode has effect only in legacy memory manager.

Class representing a worker.

A shared reference to a Kotlin object that doesn't freeze the referred object when it gets frozen itself.

Checks if given object is null or frozen or permanent (i.e. instantiated at compile-time).

Atomic lazy initializer, could be used in frozen objects, freezes initializing lambda, so use very carefully. Also, as with other uses of an AtomicReference may potentially leak memory, so it is recommended to use atomicLazy in cases of objects living forever, such as object singletons, or in cases where it's guaranteed not to have cyclical garbage.

Attaches previously detached object subgraph created by DetachedObjectGraph. Please note, that once object graph is attached, the DetachedObjectGraph.stable pointer does not make sense anymore, and shall be discarded, so attach of one DetachedObjectGraph object can only happen once.

This function ensures that if we see such an object during freezing attempt - freeze fails and FreezingException is thrown.

Freezes object subgraph reachable from this object. Frozen objects can be freely shared between threads/workers.

Wait for availability of futures in the collection. Returns set with all futures which have value available for the consumption, i.e. FutureState.COMPUTED.

Executes block with new Worker as resource, by starting the new worker, calling provided block (in current context) with newly started worker as this and terminating worker after the block completes. Note that this operation is pretty heavyweight, use preconfigured worker or worker pool if need to execute it frequently.
