public void configure(Context context)
Configurable
Request the implementing class to (re)configure itself.
When configuration parameters are changed, they must be reflected by the component asap.
There are no thread safety guarrantees on when configure might be called.

public void start()
LifecycleAware
Starts a service or component.
Implementations should determine the result of any start logic and effect
the return value of LifecycleAware.getLifecycleState()
accordingly.

public void stop()
LifecycleAware
Stops a service or component.
Implementations should determine the result of any stop logic and effect

protected BasicTransactionSemantics createTransaction()
BasicChannelSemantics
Called to create new Transaction
objects, which must
extend BasicTransactionSemantics
. Each object is used
for only one transaction, but is stored in a thread-local and
retrieved by getTransaction
for the duration of that
transaction.
