public void registerWork(javax.resource.spi.work.Work work,
                         Xid xid,
                         long timeout)
                  throws javax.resource.spi.work.WorkCompletedException

Interception of register work call to get transaction being imported to wildfly transacton client.

For importing a transaction Wildfly transaction client eventually calls SubordinationManager as Narayana XATerminators do. This wrapping then let wildfly transacton client to register the transaction for itself, wildfly transacton client then import transaction to Narayana too and finally this method uses Narayana's XATerminator to register all Works binding.
Narayana's XATerminator tries to import transaction too but as transaction is already imported it just gets instance of transaction already imported via call of wildfly transacton client.

Specified by:

registerWork in interface org.jboss.tm.JBossXATerminator

Throws:

javax.resource.spi.work.WorkCompletedException

startWork

public void startWork(javax.resource.spi.work.Work work,
                      Xid xid)
               throws javax.resource.spi.work.WorkCompletedException

Start work gets imported transaction and assign it to current thread.

This method mimics behavior of Narayana's JBossXATerminator.

Specified by:

startWork in interface org.jboss.tm.JBossXATerminator

Throws:

javax.resource.spi.work.WorkCompletedException

endWork

public void endWork(javax.resource.spi.work.Work work,
                    Xid xid)

Suspending transaction and canceling the work.

Suspend transaction has to be called on the wildfly transaction manager and the we delegate work cancellation to JBossXATerminator.
First we have to cancel the work for jboss terminator would not work with suspended transaction.

Specified by:

endWork in interface org.jboss.tm.JBossXATerminator

cancelWork

public void cancelWork(javax.resource.spi.work.Work work,
                       Xid xid)

Calling JBossXATerminator to cancel the work for us.

There should not be need any action to be processed by wildfly transaction client.

Specified by:

cancelWork in interface org.jboss.tm.JBossXATerminator
