Method Detail

isProcessAlive

public static boolean isProcessAlive(long pid)

Returns true if the given PID is still alive

getProcessIds

public static List<Long> getProcessIds()

Returns the list of current active PIDs

getJavaProcessIds

public static List<Long> getJavaProcessIds(String... classNameFilter)

Returns the list of current active PIDs for any java based process that has a main class which contains any of the given bits of text

killJavaProcesses

public static int killJavaProcesses()

Kills all commonly created Java based processes created by fabric8 and its unit tests. This is handy for unit testing to ensure there's no stray karaf, wildfly, tomcat or java containers running.

killJavaProcesses

public static int killJavaProcesses(String... classNameFilters)

Kills all java processes found which include the classNameFilter in their main class

getDockerContainerIds

public static List<String> getDockerContainerIds()

Returns a list of active docker containers

killDockerContainer

public static int killDockerContainer(String containerId)

Returns a list of active docker containers

killDockerContainers

public static void killDockerContainers()

Kills all docker containers on the current host

killProcess

public static int killProcess(Long pid,
              String params)

Attempts to kill the given process

killProcessWindows

protected static int killProcessWindows(Long pid,
                     String params)

killProcessUnix

protected static int killProcessUnix(Long pid,
                  String params)

                                 throws Exception

Throws:

Exception

processOutput

protected static void processOutput(InputStream inputStream,
                 Function<String,Void> function,
