public class DavidTSHandler

extends TSHandler

Provides an implementation of a CORBA COS Transaction service handler that conforms to the CosTSPortability module but that uses Java specific (i.e., non CORBA) means of encoding and decoding transaction contexts.

Field Summary

protected DavidStreamFactory

mf The marshaller factory parameter used to encode/decode contexts.

Constructor Summary

protected

DavidTSHandler(Context c, Object[] used_components) Builds a new Jeremie transaction service handler instance.

Method Summary

protected org.omg.CosTransactions.PropagationContext	decodeContext(org.omg.IOP.ServiceContext sc) Decodes a Transaction Service propagation context from an IOP service context.
protected org.omg.IOP.ServiceContext	encodeContext(org.omg.CosTransactions.PropagationContext ctx) Encodes a Transaction Service propagation context into an IOP service context.

Constructor Detail

DavidTSHandler

protected DavidTSHandler(Context c,
                         Object[] used_components)
                  throws JonathanException

Builds a new Jeremie transaction service handler instance.

used_components must be an array of 4 objects. The first is an Integer whose value is the transaction service id; If the value equals Integer.MAX_VALUE, then the value defaults to service_id; the second is a (possibly null) Sender instance; the third is a possibly null Receiver instance; the fourth is a DavidStreamFactory instance.

Parameters:

c - unused

used_components - the components used to initialize the new DavidTSHandler.

Throws:

JonathanException - if something goes wrong.

Method Detail

encodeContext

protected org.omg.IOP.ServiceContext encodeContext(org.omg.CosTransactions.PropagationContext ctx)

Encodes a Transaction Service propagation context into an IOP service context.

Overrides:

encodeContext in class TSHandler

Parameters:

ctx - the propagation context to be encoded.

Returns:

the resulting IOP service context.

decodeContext

protected org.omg.CosTransactions.PropagationContext decodeContext(org.omg.IOP.ServiceContext sc)

Decodes a Transaction Service propagation context from an IOP service context.

Overrides:

decodeContext in class TSHandler

Parameters:

ctx - the IOP service context containing the encoded propagation context.

Returns:

the decoded propagation context.
