A Log Action defines how a log entry is handled after being trapped. Log Action is an abstract class which means that it has no instances. Instances are only created from its sub-classes.

has sub-classes: EmailLogAction^c, GraphStorageAction^c, LogFileAction^c, ReplacementErrorAction^c, VirtuosoDebugAction^c, VirtuosoLogSystemAction^c
is in range of: hasLogAction^op

LogHandler^c back to ToC or Class ToC

IRI: http://www.openlinksw.com/ontology/logging#LogHandler

is defined by: http://www.openlinksw.com/ontology/logging#

A Log Handler describes a way how a log message or error should be handled. Entries are trapped via a LogPattern and then handled according to a set of LogActions. A LogHandler without a LogPattern will match all incoming messages and errors.
