Constructor Detail

SpanImpl

public SpanImpl(SpiSpecificSpan spiSpecificSpan,
                SpanType spanType,
                Set<Scope> includedScopes)

Constructor

Parameters:

spiSpecificSpan - Spi specific span.

spanType - Type of a span.

includedScopes - Set of included scopes.

Method Detail

addTag

public Span addTag(String tagName,
                   Supplier<String> tagValSupplier)

Adds tag to span with String value.

Specified by:

addTag in interface Span

Parameters:

tagName - Tag name.

tagValSupplier - Tag value supplier. Supplier is used instead of strict tag value cause of it's lazy nature. So that it's possible not to generate String tag value in case of NoopSpan.

addLog

public Span addLog(Supplier<String> logDescSupplier)

Logs work to span.

Specified by:

addLog in interface Span

Parameters:

logDescSupplier - Log description supplier. Supplier is used instead of strict log description cause of it's lazy nature. So that it's possible not to generate String log description in case of NoopSpan.

setStatus

public Span setStatus(SpanStatus spanStatus)

Explicitly set status for span.

Specified by:

setStatus in interface Span

Parameters:

spanStatus - Status.

Specified by:

type in interface Span

Returns:

Type of given span.

includedScopes

public Set<Scope> includedScopes()

Specified by:

includedScopes in interface Span

Returns:

Set of included scopes.

spiSpecificSpan

public SpiSpecificSpan spiSpecificSpan()

Returns:

Spi specific span delegate.
