Constructor Summary

MEvent(byte[] eventBytes)
This method serves to unmarshall an event stream received over the link.

MEvent(String eventString)
This MEvent constructor is used only by the JmsEventRoutingProtocol

MEvent(String eventString, int messageSize)
The MEvent constructor.

Method Summary

byte[]	getBytes() This method returns the MEvent as a stream of bytes, the unmarshalling counterpart to this marshalling scheme is contained within one of the MEvent constructors
int	getMessageSize()
String	getNextTag() This returns the next tag, that is contained in the pairs associated with the event.
String	getTagValue(String tag) This method returns the value associated with a tag
long	getTimeStamp() This method returns the timestamp associated with the event
static void	main(String[] args)
void	resetLocalPointer()
void	setTimeStamp(long timeStamp)
String	toString() Provides a string representation of the event.

Constructor Detail

MEvent

public MEvent(String eventString,
              int messageSize)

The MEvent constructor.

Parameters:

eventString - The event string that we use to construct the String.

messageSize - This fixes the size of the message, by padding extra bytes.

MEvent

public MEvent(String eventString)

This MEvent constructor is used only by the JmsEventRoutingProtocol

Parameters:

eventString - The event string that we use to construct the String.

MEvent

public MEvent(byte[] eventBytes)

This method serves to unmarshall an event stream received over the link. The corresponding marshalling method for the event is contained within the getBytes() method.

Parameters:

eventBytes - The marshalled stream of event bytes that are received over a link.

Method Detail

getTimeStamp

public long getTimeStamp()

This method returns the timestamp associated with the event

Returns:

The timeStamp

setTimeStamp

public void setTimeStamp(long timeStamp)

getMessageSize

public int getMessageSize()

resetLocalPointer

public void resetLocalPointer()

getTagValue

public String getTagValue(String tag)

This method returns the value associated with a tag

Parameters:

tag - The tag for which we are seeking a value.

getNextTag

public String getNextTag()

This returns the next tag, that is contained in the pairs associated with the event.

Returns:

The next tag in the tag-value sequence

getBytes

public byte[] getBytes()

This method returns the MEvent as a stream of bytes, the unmarshalling counterpart to this marshalling scheme is contained within one of the MEvent constructors

Returns:

The byte stream representation of the MEvent

toString

public String toString()

Provides a string representation of the event.

Overrides:

toString in class Object

Returns:

String representation of the event

main

public static void main(String[] args)
