Compressing a Single Message

To enable message compression on a per-message basis, the following methods are provided. Note that in the interface code, the compression ratio for a sent message is calculated as follows:

ratio = ((uncompressed - compressed)/uncompressed) * 100

For JMS messaging:

public interface WmMessage {

// Enables or disables compression for this message.
public void setCompression(boolean compress);

// Get the value for whether compression is enabled or disabled.
public void getCompression();

// Get the compression ratio for message that was sent.
public int getCompressionRatio();
}

The following example shows how to compress a single message for JMS.

// Create a topic publisher.
TopicPublisher pub = session.createPublisher(topic);

// Create a text message.
TextMessage msg = session.createTextMessage(text);

// Set the compression.
msg.setCompression(true);

// Publish the message.
pub.publish(msg);

// Print the compression ratio.
int ratio = ((WmMessage) msg).getCompressionRatio();
System.out.println("compression ratio = " + ratio);

For C# messaging:

Boolean Compression () }
{
set;
get;
}
int CompressionRatio
{
get;
}
}

The following example shows how to compress a single message for C#.

// Create a topic publisher.
IMessageProducer pub = session.createPublisher(topic);

// Create a text message.
ITextMessage msg = session.createTextMessage(text);

// Set the compression.
msg.Compression = true;

// Publish the message.
pub.publish(msg);

// Print the compression ratio.
int ratio = msg.CompressionRatio;
System.out.println("compression ratio = " + ratio);
