public TransactionSynchronizationRegistryImpl(TransactionManager t)
public Object getTransactionKey()
hashCode and equals methods to allow
its use as the key in a java.util.HashMap for use by the
caller. If there is no transaction currently active, null is returned.
The returned object will return the same hashCode and
compare equal to all other objects returned by calling this method
from any component executing in the same transaction context in the
same application server.
The toString method returns a String
that might be usable by a human reader to usefully understand the
transaction context. The result of the toString method
is otherwise not defined. Specifically, there is no forward or backward
compatibility guarantee for the result returned by the
toString method.
The object is not necessarily serializable, and is not useful outside the virtual machine from which it was obtained.

Synchronization instance with special ordering
semantics. The beforeCompletion method on the registered
Synchronization will be called after all user and
system component beforeCompletion callbacks, but before
the 2-phase commit process starts. This allows user and system components to
flush state changes to the caching manager, during their
SessionSynchronization callbacks, and allows managers
to flush state changes to Connectors, during the callbacks
registered with this method. Similarly, the afterCompletion
callback will be called after 2-phase commit completes but before
any user and system afterCompletion callbacks.
The beforeCompletion callback will be invoked in the
transaction context of the current transaction bound to the thread
of the caller of this method, which is the same transaction context
active at the time this method is called. Allowable methods include
access to resources, for example, Connectors. No access is allowed to
user components, for example, timer services or bean methods,
as these might change the state of POJOs, or plain old Java objects,
being managed by the caching manager.
The afterCompletion callback will be invoked in an
undefined transaction context. No access is permitted to resources or
user components as defined above. Resources can be closed, but
no transactional work can be performed with them.
Other than the transaction context, no component J2EE context is active during either of the callbacks.
