 public class Event extends ParametersHeader implements EventHeader {

    
Comment for serialVersionUID
 
     private static final long serialVersionUID = -6458387810431874841L;
 
     protected String eventType;

    
Creates a new instance of Event
 
     public Event() {
         super();
     }

    
Sets the eventType to the newly supplied eventType string.

Parameters:
eventType - the new string defining the eventType supported in this EventHeader
Throws:
java.text.ParseException which signals that an error has been reached unexpectedly while parsing the eventType value.
 
     public void setEventType(String eventTypethrows ParseException {
         if (eventType == null)
             throw new NullPointerException(" the eventType is null");
         this. = eventType;
     }

    
Gets the eventType of the EventHeader.

Returns:
the string object identifing the eventType of EventHeader.
 
     public String getEventType() {
         return ;
     }

    
Sets the id to the newly supplied eventId string.

Parameters:
eventId - the new string defining the eventId of this EventHeader
Throws:
java.text.ParseException which signals that an error has been reached unexpectedly while parsing the eventId value.
 
     public void setEventId(String eventIdthrows ParseException {
         if (eventId == null)
             throw new NullPointerException(" the eventId parameter is null");
         setParameter(.eventId);
     }

    
Gets the id of the EventHeader. This method may return null if the "eventId" is not set.

Returns:
the string object identifing the eventId of EventHeader.
    public String getEventId() {
        return getParameter(.);
    }

    
Encode in canonical form.

Returns:
String
    public String encodeBody() {
        return encodeBody(new StringBuffer()).toString();
    }
    protected StringBuffer encodeBody(StringBuffer buffer) {
        if ( != null)
            buffer.append();
        if (!.isEmpty()) {
            buffer.append();
            this..encode(buffer);
        }
        return buffer;
    }

    
Return true if the given event header matches the supplied one.

Parameters:
matchTarget -- event header to match against.
    public boolean match(Event matchTarget) {
        if (matchTarget.eventType == null && this. != null)
            return false;
        else if (matchTarget.eventType != null && this. == null)
            return false;
        else if (this. == null && matchTarget.eventType == null)
            return false;
        else if (getEventId() == null && matchTarget.getEventId() != null)
            return false;
        else if (getEventId() != null && matchTarget.getEventId() == null)
            return false;
        return matchTarget.eventType.equalsIgnoreCase(this.)
