                                               ProcessFilter filter,
                                               int delaySeconds)

Specified by:

getPsPpidCommand

@NotNull
protected abstract String[] getPsPpidCommand()

getAlternativePsPpidCommand

@Nullable
protected String[] getAlternativePsPpidCommand()

getProcessVisitor

@NotNull
protected ProcessTreeWrapper getProcessVisitor(@NotNull
                                               ProcessFilter filter,
                                               int delaySeconds)

killProcessTree

public boolean killProcessTree(@Nullable
                               Long pid,

                               int commandTimeout)

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

Specified by:

killProcessTree in interface ProcessTerminatorSupport

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.
