EventWriter (OpenNMS 2020.1.14 API)

All Superinterfaces:

EventProcessor

All Known Implementing Classes:

HibernateEventWriter
```
public interface EventWriter
extends EventProcessor
```
EventWriter stores the information for each 'Event' into the database. While loading multiple values of the same element into a single DB column, the multiple values are delimited by MULTIPLE_VAL_DELIM. When an element and its attribute are loaded into a single DB column, the value and the attribute are separated by a DB_ATTRIB_DELIM. When using delimiters to append values, if the values already have the delimiter, the delimiter in the value is escaped as in URLs. Values for the ' ' block are loaded with each parm name and parm value delimited with the NAME_VAL_DELIM.

Use "auto-clean" attribute in eventconf files.
