Method Detail

spiStart

public void spiStart(@Nullable
                     String igniteInstanceName)
              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:

igniteInstanceName - 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.

sendMessage

public void sendMessage(ClusterNode destNode,
                        Serializable msg)
                 throws IgniteSpiException

Sends given message to destination node. Note that characteristics of the exchange such as durability, guaranteed delivery or error notification is dependant on SPI implementation.

Specified by:

sendMessage in interface CommunicationSpi

Parameters:

destNode - Destination node.

msg - Message to send.

Throws:

IgniteSpiException - Thrown in case of any error during sending the message. Note that this is not guaranteed that failed communication will result in thrown exception as this is dependant on SPI implementation.

getSentMessagesCount

public int getSentMessagesCount()

Gets sent messages count.

Specified by:

getSentMessagesCount in interface CommunicationSpi

Returns:

Sent messages count.

getSentBytesCount

public long getSentBytesCount()

Specified by:

getSentBytesCount in interface CommunicationSpi

Returns:

Sent bytes count.

getReceivedMessagesCount

public int getReceivedMessagesCount()

Specified by:

getReceivedMessagesCount in interface CommunicationSpi

Returns:

Received messages count.

getReceivedBytesCount

public long getReceivedBytesCount()

Gets received bytes count.

Specified by:

getReceivedBytesCount in interface CommunicationSpi

Returns:

Received bytes count.

getOutboundMessagesQueueSize

public int getOutboundMessagesQueueSize()

Gets outbound messages queue size.

Specified by:

getOutboundMessagesQueueSize in interface CommunicationSpi

Returns:

Outbound messages queue size.

resetMetrics

public void resetMetrics()

Resets metrics for this SPI instance.

Specified by:

resetMetrics in interface CommunicationSpi

setListener

public void setListener(@Nullable
                        CommunicationListener lsnr)

Set communication listener.

Specified by:

setListener in interface CommunicationSpi

Parameters:

lsnr - Listener to set or null to unset the listener.
