Method Detail

create

public NoopSpiSpecificSpan create(@NotNull
                                  @NotNull String name,
                                  @Nullable
                                  @org.jetbrains.annotations.Nullable byte[] serializedSpan)

Creates Span given name and explicit parent.

Specified by:

create in interface TracingSpi<NoopSpiSpecificSpan>

Parameters:

name - Name of span to create.

serializedSpan - Parent span as serialized bytes.

Returns:

Created span.

create

@NotNull
public @NotNull NoopSpiSpecificSpan create(@NotNull
                                           @NotNull String name,
                                           @Nullable
                                           @Nullable NoopSpiSpecificSpan parentSpan)

Creates Span given name and explicit parent.

Specified by:

create in interface TracingSpi<NoopSpiSpecificSpan>

Parameters:

name - Name of span to create.

parentSpan - Parent span.

Returns:

Span instance.

serialize

public byte[] serialize(@NotNull
                        @NotNull NoopSpiSpecificSpan span)

Serializes span to byte array to send context over network.

Specified by:

serialize in interface TracingSpi<NoopSpiSpecificSpan>

Parameters:

span - Span.

Returns:

Span instance.

spiStart

public void spiStart(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.

type

public byte type()

Specified by:

type in interface TracingSpi<NoopSpiSpecificSpan>

Returns:

type of tracing spi as byte.
