Method Detail

_enable

protected abstract void _enable()

_disable

protected abstract void _disable()

_isPrimary

protected abstract boolean _isPrimary()

enable

public void enable()

Description copied from interface: SingleProducerEnforcer

Mark producer to enable processing cycles. Default implementation (BasicSingleProducerEnforcer) is enabled by default.

Specified by:

enable in interface SingleProducerEnforcer

disable

public void disable()

Description copied from interface: SingleProducerEnforcer

Relinquish the primary producer status. disable() can be invoked any time, but takes affect only after current cycle is completed (or if no cycle is running).

Specified by:

disable in interface SingleProducerEnforcer

isPrimary

public boolean isPrimary()

Description copied from interface: SingleProducerEnforcer

runCycle() is executed only if isPrimary() is true

Specified by:

isPrimary in interface SingleProducerEnforcer

Returns:

boolean

onCycleStart

public void onCycleStart(long version)

Description copied from interface: HollowProducerListener

Called when the HollowProducer has begun a new cycle.

Specified by:

onCycleStart in interface HollowProducerListener

Overrides:

onCycleStart in class AbstractHollowProducerListener

Parameters:

version - Version produced by the HollowProducer for new cycle about to start.

onCycleComplete

public void onCycleComplete(HollowProducerListener.ProducerStatus status,
                   long elapsed,
                   java.util.concurrent.TimeUnit unit)

Description copied from interface: HollowProducerListener

Called after HollowProducer has completed a cycle normally or abnormally. A SUCCESS status indicates that the entire cycle was successful and the producer is available to begin another cycle.

Specified by:

onCycleComplete in interface HollowProducerListener

Overrides:

onCycleComplete in class AbstractHollowProducerListener

Parameters:

status - ProducerStatus of this cycle. HollowProducerListener.ProducerStatus.getStatus() will return SUCCESS when the a new data state has been announced to consumers or when there were no changes to the data; it will return @{code FAIL} when any stage failed or any other failure occured during the cycle.

elapsed - duration of the cycle in unit units

unit - units of the elapsed duration

getWasPrimary

protected boolean getWasPrimary()
