Examples of org.yaml.snakeyaml.events.MappingStartEvent

org.yaml.snakeyaml.events.MappingStartEvent
Marks the beginning of a mapping node.
This event is followed by a number of key value pairs.
The pairs are not in any particular order. However, the value always directly follows the corresponding key.
After the key value pairs follows a {@link MappingEndEvent}.

There must be an even number of node events between the start and end event.
