Examples of bitronix.tm.internal.XAResourceHolderState

bitronix.tm.internal.XAResourceHolderState
{@link XAResourceHolder} state container.Instances are kept in the transaction and bound to / unbound from the {@link XAResourceHolder} as theresource participates in different transactions. A {@link XAResourceHolder} without {@link XAResourceHolderState}is considered to be in local transaction mode.
Objects of this class also expose resource specific configuration like the unique resource name.

The {@link XAResource} state during a transaction participation is also contained: assigned XID, transactionstart / end state...

There is exactly one {@link XAResourceHolderState} object per {@link XAResourceHolder} per{@link javax.transaction.Transaction}.
