Class SimpleProcess

java.lang.Object

com.exasol.extensionmanager.itest.process.SimpleProcess

public class SimpleProcess
extends Object

This is a convenient wrapper for ProcessBuilder and Process that simplifies starting a process, waiting for it to finish and getting its stdout.

Method Summary

Modifier and Type	Method	Description

Method Detail

start

public static String start(List<String> command,
                           Duration executionTimeout)

Starts a new process using the working directory of the current Java process and waits until it terminates successfully.

Parameters:

command - command to execute

executionTimeout - execution timeout for the process

Returns:

combined stdout and stderr from the process

start

public static String start(Path workingDirectory,
                           List<String> command,
                           Duration executionTimeout)

Starts a new process using the given working directory and waits until it terminates successfully.

Parameters:

workingDirectory - directory in which to start the process. Use the working directory of the current Java process if null.

command - command to execute

executionTimeout - execution timeout for the process

Returns:

combined stdout and stderr from the process

start

public static SimpleProcess start(List<String> command,
                                  ProcessStreamConsumer outputStreamConsumer,
                                  ProcessStreamConsumer errorStreamConsumer)

Starts a new process using the working directory of the current Java process.

Parameters:

command - command to execute

outputStreamConsumer - ProcessStreamConsumer for the output stream

errorStreamConsumer - ProcessStreamConsumer for the error stream

Returns:

a new SimpleProcess you can use to wait for the process to finish and retrieve its output

start

public static SimpleProcess start(Path workingDirectory,
                                  List<String> command,
                                  ProcessStreamConsumer outputStreamConsumer,
                                  ProcessStreamConsumer errorStreamConsumer)

Starts a new process.

Parameters:

workingDirectory - directory in which to start the process. Use the working directory of the current Java process if null

command - command to execute

outputStreamConsumer - ProcessStreamConsumer for the output stream

errorStreamConsumer - ProcessStreamConsumer for the error stream

Returns:

a new SimpleProcess you can use to wait for the process to finish and retrieve its output

waitUntilTerminatedSuccessfully

public void waitUntilTerminatedSuccessfully(Duration executionTimeout)

Wait for the process to terminate successfully.

Parameters:

executionTimeout - maximum time to wait until the process finishes

Throws:

IllegalStateException - if the process did not finish within the given timeout or returned an exit code other than 0

stop

public void stop()

Destroy a running process.
