Method Detail

init

public static void init()

Initializes process tree terminator

kill

public static boolean kill(@Nullable
                           Long pid,
                           KillProcessDetails killProcessDetails)

Kills process specified by pid and it's subprocesses matched by specified filter. If pid parameter is null, kills current process's subtree. Avoids killing current process

Parameters:

pid - process pid

killProcessDetails - kill process details

Returns:

should return the actual status if the process was killed, but current implementation may return true even if the process was not killed.

kill

public static boolean kill(KillProcessDetails killProcessDetails)

Kills child processes matched by specified filter.

Parameters:

killProcessDetails - kill process details

Returns:

should return the actual status if the process was killed, but the current implementation may return true even if the process was not killed.

getChildProcesses

public static Collection<ProcessNode> getChildProcesses(@Nullable
                                                        Long pid,
                                                        @NotNull
                                                        ProcessFilter filter)

Returns child processes of the process specified by rge pid matched by the specified filter

Parameters:

filter - process filter

Returns:

collection of child processes

getChildProcesses

public static Collection<ProcessNode> getChildProcesses(@NotNull
                                                        ProcessFilter filter)

Returns child processes matched by the specified filter

Parameters:

filter - process filter

Returns:

collection of child processes

getCurrentPid

public static long getCurrentPid()

Gets current process's pid. This operation may take appreciable timed ue to process tree rebuild

Returns:

process pid
