Package org.apache.axis2.context

Class SessionContext

java.lang.Object

org.apache.axis2.context.AbstractContext

org.apache.axis2.context.SessionContext

All Implemented Interfaces:

Externalizable, Serializable, SafeSerializable

public class SessionContext
extends AbstractContext
implements Externalizable, SafeSerializable

All the engine components are stateless across the executions and all the states should be kept in the Contexts, there are three context Global, Session and Message.

ServiceContext and ServiceGroupContext are not getting automatically garbage collectible. And there is no specific way for some one to go and make it garbage collectable. So the current solution is to make them time out. So the logic is that, there is a timer task in each and every service group which will check for the last touched time. And if it has not been touched for some time, the timer task will remove it from the memory. The touching logic happens like this. Whenever there is a call to addMessageContext in the operationContext it will go and update operationCOntext -> serviceContext -> serviceGroupContext.

Overrides:

touch in class AbstractContext

getLastTouchedTime

public long getLastTouchedTime()

Overrides:

getLastTouchedTime in class AbstractContext

getServiceGroupContext

public Iterator<ServiceGroupContext> getServiceGroupContext()

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable

writeExternal

public void writeExternal(ObjectOutput o)
                   throws IOException

Save the contents of this object.

NOTE: Transient fields and static fields are not saved.

Specified by:

writeExternal in interface Externalizable

Parameters:

out - The stream to write the object contents to

Throws:

IOException

readExternal

public void readExternal(ObjectInput inObject)
                  throws IOException,
                         ClassNotFoundException

Restore the contents of the MessageContext that was previously saved.

NOTE: The field data must read back in the same order and type as it was written. Some data will need to be validated when resurrected.
