Method Detail

localEvents

public <T extends Event> Collection<T> localEvents(IgnitePredicate<T> p)

Queries locally-stored events only. Events could be filtered out by given predicate filter.

Specified by:

localEvents in interface EventStorageSpi

Type Parameters:

T - Type of events.

Parameters:

p - Event predicate filter.

Returns:

Collection of events.

record

public void record(Event evt)
            throws IgniteSpiException

Records single event.

Specified by:

record in interface EventStorageSpi

Parameters:

evt - Event that should be recorded.

Throws:

IgniteSpiException - If event recording failed for any reason.

spiStart

public void spiStart(@Nullable
                     @Nullable String gridName)
              throws IgniteSpiException

This method is called to start SPI. After this method returns successfully kernel assumes that SPI is fully operational.

Specified by:

spiStart in interface IgniteSpi

Parameters:

gridName - Name of Ignite instance this SPI is being started for (null for default Ignite instance).

Throws:

IgniteSpiException - Throws in case of any error during SPI start.

spiStop

public void spiStop()
             throws IgniteSpiException

This method is called to stop SPI. After this method returns kernel assumes that this SPI is finished and all resources acquired by it are released.

Note that this method can be called at any point including during recovery of failed start. It should make no assumptions on what state SPI will be in when this method is called.

Specified by:

spiStop in interface IgniteSpi

Throws:

IgniteSpiException - Thrown in case of any error during SPI stop.
