-- ======================
-- Description
-- ======================
--
-- Logika obsługująca wartości priorytetowe.
-- Do wartości output.value jest kopiowana wartość input.value pod warunkiem, że nie został uaktywniony żaden priorytet.
--
-- Jeżeli priorytet został uaktywniony (input.priority.signal) i ten priorytet jest aktywny (setting.priority.enabled) to wówczas do
-- wartości output.value jest kopiowana wartość tego priorytetu (setting.priority.value).
--
-- Jeżeli aktywnych jest kilka priorytetów to wybierany jest priorytet z najniższą wartością setting.prioryty.lvl.
--
-- ======================
-- Parameters
-- ======================
--
-- SubLogic supports following variables:
--
-- input.value - wartość wejściowa
--
-- input.priority.signal - Lista. Aktywacja priorytetu [0 - priorytet nieaktywny, różny od 0 - priorytet aktywny].
--
-- output.value - obliczona wartość wyjściowa
--
-- setting.priority.value - Lista. Ta wartość jest kopiowana do output.value w przypadku wybrania priorytetu (najwyższy poziom priorytetu,
-- priorytet aktywny, priorytet włączony).
--
-- setting.priority.enabled - Lista. Czy dany priorytet jest włączony [0 - priorytet wyłączony, różny od 0 - priorytet włączony].
--
-- setting.prioryty.lvl - Lista. Poziom priorytetu. Im niższa wartość tym większy priorytet.
--
-- counter.prioryty.count - Ilość zdefiniowanych priorytetów
--
--
-- Logic uses lua language to implement own behaviour
--
-- ======================
-- mandatory variables
-- ======================
--
-- Logic expects following mandatory variables:
--
-- reload.trigger - causes reloading lua script
--
-- memcnt - current amount of memory used by lua in bytes
--
-- Logic expects following kv settings:
--
-- LuaScriptPath - path to the lua script - must be absolute

--
-- user can use some functions provided by ibmanager.
-- ibmanager provides following functions to use:
--
-- function returns value of required ibmanager variable
-- @param fullName - string - variable name - name of variable of which value must be returned, for example "rs.0.id.255.input.t.0.value"
-- @return - string or integer - variable value or "nil" if variable not exist or is not readable
--
-- getValue(fullName)
-- function set value of given ibmanager variable
-- @param fullName - string - variable name - name of variable of which value we want to set, for example "rs.0.id.255.input.t.0.value"
-- @param value - string, int or boolean - value to set
-- @return - nothing
--
-- setValue(fullName, value)
-- function returns value of required ibmanager variable
-- @param key - placed in xml logic configuration file:
-- * as attribute: Name, in Var, RemoteVar and ImportVar elements in the case of stand alone variables
-- * as concatenation of two attributes: ListName.Postfix in VarListItem, RemoteVarListItem and ImportVarListItem elements
-- in the case of variables that are placed in lists
-- @return - string or integer - variable value or "nil" if variable not exist or is not readable
--
-- getLogicValue(key)
-- function set value of given ibmanager variable
-- @param key - placed in xml logic configuration file:
-- * as attribute: Name, in Var, RemoteVar and ImportVar elements in the case of stand alone variables
-- * as concatenation of two attributes: ListName.Postfix in VarListItem, RemoteVarListItem and ImportVarListItem elements
-- in the case of variables that are placed in lists
-- @param value - string, int or boolean - value to set
-- @return - nothing
--
-- setLogicValue(key, value)
-- function returns two sections of kvsettings from xml configuration file
-- returned value is two element table, each of these elements is table too.
-- indices of returned table are strings and equal "instance" and "global"
-- values of returned tables are tables and contain KVsettings for applicable section.
-- nested tables have form key = value, where key is index in nested table and value is value.
-- example: {"instance" = {"ikey1" = "ivalue1", "ikey2" = "gvalue2"}, "global" = {"gkey1" = "gvalue1", "gkey2" = "gvalue2", "gkey3" = "gvalue3"}}
-- @return - two dimensional array - kvsettings for global and instance sections
-- getKvSettings()
-- function schedules alert to send.
-- rules are defined in separated alert configuration files and are described in ibmanager instruction manual
-- @param id - alert identifier - must be defined in current logic configuration file in section: <Alert Id="any_identifier" ...
-- scheduleAlert(id)
-- function cancels alert sending, if was previously scheduled. if not then only wakes up alerts handling thread, so if there is no need to call this function, then do not call it.
-- rules are defined in separated alert configuration files and are described in ibmanager instruction manual
-- @param id - alert identifier - must be defined in current logic configuration file in section: <Alert Id="any_identifier" ...
-- cancelAlert(name)
-- function returns table, containing Variables that belongs to required list.
-- @param listName - Name attribute of VarList, RemoteVarList or ImportVarList elemetnst in configurationfile
-- @return array of key-value pairs. Key - variable postfix, Value - Variable value
-- getVarList(listName)
-- function returns monotonic system clock value, that elapsed since specific epoch
-- returned time is expressed in milliseconds.
-- getClock()
-- function logs message to file, if defined in configuration file log level is less than passed to this function
-- @param logLevel - one of:
-- LogLevel.TraceLo
-- LogLevel.Trace
-- LogLevel.TraceHi
-- LogLevel.DebugLo
-- LogLevel.Debug
-- LogLevel.DebugHi
-- LogLevel.Info
-- LogLevel.Notice
-- LogLevel.Warning
-- LogLevel.Error
-- LogLevel.Critical
-- @param logMessage - string to log
-- log(logLevel, logMessage)
