+/**
+ * This class defines an Apex event. An {@link AxEvent} is used to kick off execution of policies in Apex and is emitted
+ * by policies when they completer execution. In addition, Apex uses {@link AxEvent} instances internally to pass
+ * control from one Apex state to the next during execution.
+ * <p>
+ * The {@link AxArtifactKey} of an event uniquely identifies it in an Apex system and the name field in the key is the
+ * name of the event.
+ * <p>
+ * Each {@link AxEvent} has a name space, which is usually set to identify the domain of application of an event. For
+ * example a 4G cell power event might have the name space {@code org.onap.radio.4g} and the name {@code PowerEvent}.
+ * The source and target of the event are reserved to hold an identifier that defines the sender and receiver of an
+ * event respectively. The definition and structure of these fields is reserved for future use and their use by
+ * applications is currently not recommended.
+ * <p>
+ * The parameters that an event has are defined as a map of {@link AxField} instances.
+ * <p>
+ * Validation checks that the event key is valid. If name space is a blank string, a warning is issued. Blank source or
+ * target fields result in observations being issued. An event may not have any parameters. If it has parameters, the
+ * name and value of each parameter entry is checked to ensure they are not null. Then the local name of each parameter
+ * is checked to ensure it matches the event parameter key on the event. Finally, the parent key of each parameter is
+ * checked to ensure it matches the event key.
