Method Details

toCompletionStage

public static CompletionStage toCompletionStage(org.graalvm.polyglot.Value value)

Convert a Python coroutine or awaitable value into a Java CompletionStage.

Parameters:

value - The Python result value.

Returns:

A stage that completes when the Python awaitable completes.

toAwaitable

public static org.graalvm.polyglot.Value toAwaitable(org.graalvm.polyglot.Context context,
 CompletionStage<?> stage)

Wrap a Java CompletionStage as an asyncio future for Python await.

Parameters:

context - The Python context.

stage - The Java completion stage.

Returns:

An asyncio future.

setEnabled

public static void setEnabled(boolean enabled)

Set whether Python asyncio bridge execution is enabled.

Parameters:

enabled - Whether async bridge execution is enabled.
