Function Index

check_config/0	Checks whether config parameters of the rm_tman process exist and are valid.
init/1	Initialises the module with an empty state.
on/2	Message handler when the rm_loop module is fully initialized.
start_gen_component/5
start_link/1	Starts the monitor process, registers it with the process dictionary and returns its pid for use by a supervisor.

Function Details

start_gen_component/5

start_gen_component(Module :: module(),
                    Handler :: gen_component:handler(),
                    Args :: term(),

                       no_return() | ok

on/2

on(Msg :: message(), State :: state()) -> state()

Message handler when the rm_loop module is fully initialized.

start_link/1

start_link(DHTNodeGroup :: pid_groups:groupname()) -> {ok, pid()}

Starts the monitor process, registers it with the process dictionary and returns its pid for use by a supervisor.

init/1

init(X1 :: null) -> state()

Initialises the module with an empty state.

check_config/0

check_config() -> boolean()

Checks whether config parameters of the rm_tman process exist and are valid.
