ProcessPipeline

Alias for destroy, implemented for java.lang.AutoCloseable.

String representation of the pipeline.

Attempt to destroy the ProcessPipeline (gently), via the underlying JVM APIs. All processes in the pipeline are destroyed.

Force-destroys the ProcessPipeline, via the underlying JVM APIs. All processes in the pipeline are force-destroyed.

The exit code of this ProcessPipeline. Conventionally, 0 exit code represents a successful termination, and non-zero exit code indicates a failure. Throws an exception if the subprocess has not terminated.

If pipefail is set, the exit code is the first non-zero exit code of the pipeline. If no process in the pipeline has a non-zero exit code, the exit code is 0.

Returns true if the ProcessPipeline is still running and has not terminated. Any process in the pipeline can be alive for the pipeline to be alive.

Wait up to timeout for the ProcessPipeline to terminate all the processes in pipeline. By default waits indefinitely; if a time limit is given, explicitly destroys each process if it has not completed by the time the timeout has occurred.

By default, the processes are destroyed by sending SIGTERM signals, which allows an opportunity for them to clean up any resources it. If any process is unresponsive to this, a SIGKILL signal is sent timeoutGracePeriod milliseconds later. If timeoutGracePeriod is 0, then there is no SIGTERM; if it is -1, there is no SIGKILL sent.

Wait up to timeout for the ProcessPipeline to terminate, by default waits indefinitely. Returns true if the ProcessPipeline has terminated by the time this method returns.

Waits for each process one by one, while aggregating the total time waited. If timeout has passed before all processes have terminated, returns false.
