All Implemented Interfaces:

com.datadog.trace.api.interceptor.MutableSpan , io.opentracing.Span
```
public class DDSpan
 implements Span, MutableSpan
                    
```
Represents a period of time. Associated information is stored in the SpanContext.
Spans are created by the buildSpan. This implementation adds some features according to the DD agent.

Method Detail

isFinished
```
 boolean isFinished()
```

finish
```
 final void finish()
```

finish

 final void finish(long stoptimeMicros)

setError
```
 DDSpan setError(boolean error)
```

drop
```
 final void drop()
```
By calling this method the span will be removed from the current active Trace withoutactually being persisted.Note: This method is meant for internal SDK usage. Be aware that if used this Span willbe removed from the Trace and lost.

isRootSpan
```
 final boolean isRootSpan()
```
Check if the span is the root parent. It means that the traceId is the same as the spanId. Inthe context of distributed tracing this will return true if an only if this is the applicationinitializing the trace.

getRootSpan
```
@Deprecated() MutableSpan getRootSpan()
```

getLocalRootSpan
```
 MutableSpan getLocalRootSpan()
```
Returns the root span for current the trace fragment. In the context of distributed tracingthis method returns the root span only for the fragment generated by the currently tracedapplication.

setErrorMeta
```
 void setErrorMeta(Throwable error)
```

setTag

 final DDSpan setTag(String tag, String value)

setTag

 final DDSpan setTag(String tag, boolean value)

setTag

 final DDSpan setTag(String tag, Number value)

setTag
```
 <T> Span setTag(Tag<T> tag, T value)
```

context
```
 final DDSpanContext context()
```

getBaggageItem

 final String getBaggageItem(String key)

setBaggageItem

 final DDSpan setBaggageItem(String key, String value)

setOperationName

 final DDSpan setOperationName(String operationName)

log

 final DDSpan log(Map<String, out Object> map)

log

 final DDSpan log(long l, Map<String, out Object> map)

log
```
 final DDSpan log(String s)
```

log
```
 final DDSpan log(long l, String s)
```

setServiceName

 final DDSpan setServiceName(String serviceName)

setResourceName

 final DDSpan setResourceName(String resourceName)

setSamplingPriority
```
 final DDSpan setSamplingPriority(int newPriority)
```
Set the sampling priority of the root span of this span's trace
Has no effect if the span priority has been propagated (injected or extracted).
