destroy back to summary

destroy	back to summary
public void destroy() Implements abstract java.lang.Process.destroy. Doc from java.lang.Process.destroy. Kills the process. Whether the process represented by this `Process` object is normally terminated or not is implementation dependent. Forcible process destruction is defined as the immediate termination of a process, whereas normal termination allows the process to shut down cleanly. If the process is not alive, no action is taken. The `java.util.concurrent.CompletableFuture` from `onExit` is completed when the process has terminated. Annotations @Override

getErrorStream	back to summary
public InputStream getErrorStream() Implements abstract java.lang.Process.getErrorStream. Doc from java.lang.Process.getErrorStream. Returns the input stream connected to the error output of the process. The stream obtains data piped from the error output of the process represented by this `Process` object. If the standard error of the process has been redirected using `ProcessBuilder.redirectError` or `ProcessBuilder.redirectErrorStream` then this method will return a null input stream.

waitFor back to summary

waitFor	back to summary
public synchronized int waitFor() throws InterruptedException Implements abstract java.lang.Process.waitFor. Doc from java.lang.Process.waitFor. Causes the current thread to wait, if necessary, until the process represented by this `Process` object has terminated. This method returns immediately if the process has already terminated. If the process has not yet terminated, the calling thread will be blocked until the process exits. Returns:int the exit value of the process represented by this `Process` object. By convention, the value `0` indicates normal termination. Annotations @Override Exceptions InterruptedException: if the current thread is interrupted by another thread while it is waiting, then the wait is ended and an `InterruptedException` is thrown.
