OTL Syntax

MonitorChangeEventSource EventPlus.DeepMonitorChangeEventSource(Variable variable);

Description

The OTX DeepMonitorChangeEventSource is similar to event:MonitorChangeEventSource, but with additional deep change-monitoring for variables of complex datatypes like List, Map and ByteField. The deep change-monitoring shall detect changing, adding and removing of items in Lists, Maps and ByteFields in any depth. For variables of simple datatypes, this term shall behave like event:MonitorChangeEventSource. Because DeepMonitorChangeEventSource is derived from event:MonitorChangeEventSource, the term event:IsMonitorChangeEvent shall return TRUE when the Event originates from a DeepMonitorChangeEventSource.
