public StressSource()
Method Detail

configure

public void configure(Context context)
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

process

public PollableSource.Status process()
                              throws EventDeliveryException
Description copied from interface: PollableSource

Attempt to pull an item from the source, sending it to the channel.

When driven by an EventDrivenSourceRunner process is guaranteed to be called only by a single thread at a time, with no concurrency. Any other mechanism driving a pollable source must follow the same semantics.

Specified by:
process in interface PollableSource
Returns:
READY if one or more events were created from the source. BACKOFF if no events could be created from the source.
Throws:
EventDeliveryException - If there was a failure in delivering to the attached channel, or if a failure occurred in acquiring data from the source.

start

public void start()
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 AbstractSource

stop

public void stop()
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 AbstractSource
