Method Detail

configure

public void configure(Context context)
Deprecated. 
Description copied from interface: 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.

Specified by:
configure in interface Configurable
Overrides:
configure in class AbstractChannel

start

public void start()
Deprecated. 
Description copied from interface: LifecycleAware

Starts a service or component.

Implementations should determine the result of any start logic and effect the return value of LifecycleAware.getLifecycleState() accordingly.

Specified by:
start in interface LifecycleAware
Overrides:
start in class AbstractChannel

stop

public void stop()
Deprecated. 
Description copied from interface: LifecycleAware

Stops a service or component.

Implementations should determine the result of any stop logic and effect the return value of LifecycleAware.getLifecycleState() accordingly.

Specified by:
stop in interface LifecycleAware
Overrides:
stop in class AbstractChannel

createTransaction

protected BasicTransactionSemantics createTransaction()
Deprecated. 
Description copied from class: 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.

Specified by:
createTransaction in class BasicChannelSemantics
