InterruptThread
Last update:
May 18, 2026
Description
Interrupts given thread. When interrupt is called on a thread it sets interrupt status flag on CFThread. If a thread is blocked in an invocation of the ThreadJoin or sleep method, then its interrupt status will be cleared, and it will receive an InterruptedException. Interrupting a thread that is not alive need not have any effect.
Returns
None
Syntax
interruptThread()
interruptThread(threadName)Parameters
- threadName: (Optional) Name of the thread to interrupt. If you do not provide the thread name, the current thread will be interrupted.
History
- ColdFusion (2025 release): Added the function.

interruptThread();
variables.message &= "after interrupt...<br>"
variables.message &= "isInterrupted:" & isThreadInterrupted(testThreadName) & "<br>"
}
thread action="join" name="#testThreadName#"{}
