Static Methods

createVirtualOrPlatformDaemonThreadFactory(String baseNameFormat, boolean tryVirtualThreads)

public static ThreadFactory createVirtualOrPlatformDaemonThreadFactory(String baseNameFormat, boolean tryVirtualThreads)

Tries to create a thread factory for virtual threads, and otherwise falls back to creating a platform thread factory that creates daemon threads. Virtual threads are supported from JDK21.

Parameters
Name	Description
`baseNameFormat`	`String` the base name format for the threads, '-%d' will be appended to the actual thread name format
`tryVirtualThreads`	`boolean` whether to try to use virtual threads if available or not

Returns
Type	Description
`ThreadFactory`	a ThreadFactory that produces virtual threads (Java 21 or higher) or platform daemon threads

tryCreateVirtualThreadFactory(String baseNameFormat)

public static ThreadFactory tryCreateVirtualThreadFactory(String baseNameFormat)

Tries to create a ThreadFactory that creates virtual threads. Returns null if virtual threads are not supported on this JVM.

Parameter
Name	Description
`baseNameFormat`	`String`

Returns
Type	Description
`ThreadFactory`

tryCreateVirtualThreadPerTaskExecutor(String baseNameFormat)

public static ExecutorService tryCreateVirtualThreadPerTaskExecutor(String baseNameFormat)

Tries to create an ExecutorService that creates a new virtual thread for each task that it runs. Creating a new virtual thread is the recommended way to create executors using virtual threads, instead of creating a pool of virtual threads. Returns null if virtual threads are not supported on this JVM.

Parameter
Name	Description
`baseNameFormat`	`String`

Returns
Type	Description
`ExecutorService`
