Method Detail

spiStart

public void spiStart(@Nullable
                     @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.

setSystemViewRegistry

public void setSystemViewRegistry(ReadOnlySystemViewRegistry mlreg)

Sets system view registry that SPI should export. This method called before IgniteSpi.spiStart(String).

Specified by:

setSystemViewRegistry in interface SystemViewExporterSpi

Parameters:

mlreg - System view registry.

setExportFilter

public void setExportFilter(Predicate<SystemView<?>> filter)

Sets export filter. System view that not satisfy filter shouldn't be exported.

Specified by:

setExportFilter in interface SystemViewExporterSpi

Parameters:

filter - Filter.
