public static void registerLogger(org.slf4j.Logger log)

Register a signal handler to log signals on UNIX-like systems.

register

public static void register(String signal,
                            scala.Function0<Object> action)

Adds an action to be run when a given signal is received by this process.

Note that signals are only supported on unix-like operating systems and work on a best-effort basis: if a signal is not available or cannot be intercepted, only a warning is emitted.

All actions for a given signal are run in a separate thread.

Parameters:

signal - (undocumented)

action - (undocumented)
