org.eclipse.jetty.util back to summary

public Interface VirtualThreads.Configurable

Known Direct Implementers: org.eclipse.jetty.util.thread.ExecutorThreadPool, org.eclipse.jetty.util.thread.QueuedThreadPool

Implementations of this interface can be configured to use virtual threads.

Whether virtual threads are actually used depends on whether the runtime supports virtual threads and, if the runtime supports them, whether they are configured to be used via setVirtualThreadsExecutor(Executor).

Method Summary

public default Executor	Returns: the `Executor` to use to execute tasks in virtual threads getVirtualThreadsExecutor()
public default boolean	Returns: whether to use virtual threads isUseVirtualThreads() Deprecated for removal. use `getVirtualThreadsExecutor()` instead
public default void	setUseVirtualThreads(boolean whether to use virtual threads useVirtualThreads) Deprecated for removal. use `setVirtualThreadsExecutor(Executor)` instead
public default void	setVirtualThreadsExecutor(Executor the `Executor` to use to execute tasks in virtual threads executor)

Method Detail

getVirtualThreadsExecutor	back to summary
public default Executor getVirtualThreadsExecutor() Returns:Executor the `Executor` to use to execute tasks in virtual threads
