Refactor org.dcm4che3.audit.XXXXBuilder classes

[gunterze]

Refactor org.dcm4che3.audit.XXXXBuilder classes by flatting inner class Builder with containing top level class and provide method returning the built object.

Particularly, replace

public class EventIdentificationBuilder {
    final AuditMessages.EventID eventID;
    final String eventActionCode;
    final Calendar eventDateTime;
    final String outcome;
    final String outcomeDesc;
    final EventTypeCode[] eventTypeCode;

    public static class Builder {
        private final AuditMessages.EventID eventID;
        private final String eventActionCode;
        private final Calendar eventDateTime;
        private final String outcome;
        private String outcomeDesc;
        private EventTypeCode[] eventTypeCode = {};

        public Builder(AuditMessages.EventID eventID, String eventActionCode, Calendar eventDateTime, String outcome) {
            this.eventID = eventID;
            this.eventActionCode = eventActionCode;
            this.eventDateTime = eventDateTime;
            this.outcome = outcome;
        }

        public Builder outcomeDesc(String val) {
            outcomeDesc = val;
            return this;
        }

        public Builder eventTypeCode(EventTypeCode... val) {
            eventTypeCode = val;
            return this;
        }

        public EventIdentificationBuilder build() {
            return new EventIdentificationBuilder(this);
        }
    }

    private EventIdentificationBuilder(Builder builder) {
        eventID = builder.eventID;
        eventActionCode = builder.eventActionCode;
        eventDateTime = builder.eventDateTime;
        outcome = builder.outcome;
        outcomeDesc = builder.outcomeDesc;
        eventTypeCode = builder.eventTypeCode;
    }
}

by

public class EventIdentificationBuilder {
    private final AuditMessages.EventID eventID;
    private final String eventActionCode;
    private final Calendar eventDateTime;
    private final String outcome;
    private String outcomeDesc;
    private EventTypeCode[] eventTypeCode = {};

    public EventIdentificationBuilder(AuditMessages.EventID eventID, String eventActionCode, Calendar eventDateTime,
            String outcome) {
        this.eventID = eventID;
        this.eventActionCode = eventActionCode;
        this.eventDateTime = eventDateTime;
        this.outcome = outcome;
    }

    public EventIdentificationBuilder outcomeDesc(String val) {
        outcomeDesc = val;
        return this;
    }

    public EventIdentificationBuilder eventTypeCode(EventTypeCode... val) {
        eventTypeCode = val;
        return this;
    }

    public EventIdentification build() {
        EventIdentification ei = new EventIdentification();
        ei.setEventID(eventID);
        ei.setEventActionCode(eventActionCode);
        ei.setEventDateTime(eventDateTime);
        ei.setEventOutcomeIndicator(outcome);
        ei.setEventOutcomeDescription(outcomeDesc);
        for (org.dcm4che3.audit.EventTypeCode type : eventIdentificationBuilder.eventTypeCode)
            ei.getEventTypeCode().add(type);
        return ei;
    }
}

and apply analogous changes to classes ActiveParticipantBuilder, ParticipantObjectDescriptionBuilder and ParticipantObjectIdentificationBuilder.
