public interface TransactionPropagationContextFactory
Implementations of this interface are used for getting
a transaction propagation context at the client-side.
We need a specific implementation of this interface for
each kind of DTM we are going to interoperate with. (So
we may have 20 new classes if we are going to interoperate
with 20 different kinds of distributed transaction
managers.)
The reason for having the methods in this interface return
Object is that we do not really know what kind of transaction
propagation context is returned.
getTransactionPropagationContext()
Return a transaction propagation context for the transaction
currently associated with the invoking thread, or null
if the invoking thread is not associated with a transaction.
java.lang.Object
getTransactionPropagationContext(javax.transaction.Transaction tx)
Return a transaction propagation context for the transaction
given as an argument, or null
if the argument is null or of a type unknown to
this factory.
