org.jboss.jms.wireformat
Class JMSWireFormat
java.lang.Object
org.jboss.jms.wireformat.JMSWireFormat
- All Implemented Interfaces:
- java.io.Serializable, org.jboss.remoting.marshal.Marshaller, org.jboss.remoting.marshal.UnMarshaller
public class JMSWireFormat
- extends java.lang.Object
- implements org.jboss.remoting.marshal.Marshaller, org.jboss.remoting.marshal.UnMarshaller
We do not use Java or JBoss serialization to send data over the wire. Serialization adds
considerable overhead in terms of the amount of data sent (it adds class information plus block
data information) which significantly degrades performance.
Instead we define a customer wire format that minimises the amount of data sent.
The only exception to this rule is when sending an ObjectMessage which contains a user defined
object whose type is only known at run-time. In this case we use serialization.
