Method Detail- 
createpublic NoopSpiSpecificSpan create(@NotNull @NotNull String name, @Nullable @org.jetbrains.annotations.Nullable byte[] serializedSpan) Creates Span given name and explicit parent.- Specified by:
- createin 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:
- createin interface- TracingSpi<NoopSpiSpecificSpan>
- Parameters:
- name- Name of span to create.
- parentSpan- Parent span.
- Returns:
- Span instance.
 
 - 
serializepublic byte[] serialize(@NotNull @NotNull NoopSpiSpecificSpan span)Serializes span to byte array to send context over network.- Specified by:
- serializein interface- TracingSpi<NoopSpiSpecificSpan>
- Parameters:
- span- Span.
- Returns:
- Span instance.
 
 - 
spiStartpublic 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:
- spiStartin interface- IgniteSpi
- Parameters:
- igniteInstanceName- Name of Ignite instance this SPI is being started for (- nullfor default Ignite instance).
- Throws:
- IgniteSpiException- Throws in case of any error during SPI start.
 
 - 
spiStoppublic void spiStop() throws IgniteSpiExceptionThis 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:
- spiStopin interface- IgniteSpi
- Throws:
- IgniteSpiException- Thrown in case of any error during SPI stop.
 
 - 
typepublic byte type() - Specified by:
- typein interface- TracingSpi<NoopSpiSpecificSpan>
- Returns:
- type of tracing spi as byte.
