copy

public <T> CompletableFuture<T> copy(CompletableFuture<T> stage)

Returns a new CompletableFuture that is completed by the completion of the specified stage.

The new completable future is backed by the ManagedExecutor upon which copy is invoked, which serves as the default asynchronous execution facility for the new stage and all dependent stages created from it, and so forth.

When dependent stages are created from the new completable future, thread context is captured and/or cleared by the ManagedExecutor. This guarantees that the action performed by each stage always runs under the thread context of the code that creates the stage, unless the user explicitly overrides by supplying a pre-contextualized action.

Invocation of this method does not impact thread context propagation for the supplied completable future or any dependent stages created from it, other than the new dependent completable future that is created by this method.

Type Parameters:

T - completable future result type.

Parameters:

stage - a completable future whose completion triggers completion of the new completable future that is created by this method.

Returns:

the new completable future.

copy

public <T> CompletionStage<T> copy(CompletionStage<T> stage)

Returns a new CompletionStage that is completed by the completion of the specified stage.

The new completable future is backed by the ManagedExecutor upon which copy is invoked, which serves as the default asynchronous execution facility for the new stage and all dependent stages created from it, and so forth.

When dependent stages are created from the new completable future, thread context is captured and/or cleared by the ManagedExecutor. This guarantees that the action performed by each stage always runs under the thread context of the code that creates the stage, unless the user explicitly overrides by supplying a pre-contextualized action.

Invocation of this method does not impact thread context propagation for the supplied stage or any dependent stages created from it, other than the new dependent completion stage that is created by this method.

Type Parameters:

T - completion stage result type.

Parameters:

stage - a completion stage whose completion triggers completion of the new stage that is created by this method.

Returns:

the new completion stage.

getThreadContext

public SmallRyeThreadContext getThreadContext()

Returns a ThreadContext which has the same propagation settings as this ManagedExecutor, which uses this ManagedExecutor as its default executor.

Returns:

a ThreadContext with the same propagation settings as this ManagedExecutor.
