Uses of Span in io.opentracing

Methods in io.opentracing that return Span

Modifier and Type	Method and Description
Span	Tracer.activeSpan()
Span	ScopeManager.activeSpan() Return the currently active Span.
Span	Span.log(long timestampMicroseconds, Map<String,?> fields) Like log(Map<String, Object>), but with an explicit timestamp.
Span	Span.log(long timestampMicroseconds, String event) Record an event at a specific timestamp.
Span	Span.log(Map<String,?> fields) Log key:value pairs to the Span with the current walltime timestamp.
Span	Span.log(String event) Record an event at the current walltime timestamp.
Span	Span.setBaggageItem(String key, String value) Sets a baggage item in the Span (and its SpanContext) as a key/value pair.
Span	Span.setOperationName(String operationName) Sets the string name for the logical operation this span represents.
Span	Span.setTag(String key, boolean value) Same as setTag(String, String), but for boolean values.
Span	Span.setTag(String key, Number value) Same as setTag(String, String), but for numeric values.
Span	Span.setTag(String key, String value) Set a key:value tag on the Span.
<T> Span	Span.setTag(Tag<T> tag, T value) Same as setTag(String, String), but with using Tag.
Span	Scope.span() Deprecated. use Span directly or access it through ScopeManager.activeSpan() Return the corresponding active Span for this instance.
Span	Tracer.SpanBuilder.start() Returns a newly-started Span.
Span	Tracer.SpanBuilder.startManual() Deprecated. use Tracer.SpanBuilder.start() instead.

Methods in io.opentracing with parameters of type Span

Modifier and Type	Method and Description
Scope	ScopeManager.activate(Span span) Set the specified Span as the active instance for the current context (usually a thread).
Scope	ScopeManager.activate(Span span, boolean finishSpanOnClose) Deprecated. use ScopeManager.activate(Span) instead. Set the specified Span as the active instance for the current context (usually a thread). Finishing the Span upon Scope.close() is discouraged, as reporting errors becomes impossible: try (Scope scope = tracer.scopeManager().activate(span, true)) { } catch (Exception e) { // Not possible to report errors, as // the span has been already finished. }
Scope	Tracer.activateSpan(Span span) Make a Span instance active for the current context (usually a thread).
Tracer.SpanBuilder	Tracer.SpanBuilder.asChildOf(Span parent) A shorthand for addReference(References.CHILD_OF, parent.context()).

Uses of Span in io.opentracing.tag

Methods in io.opentracing.tag with parameters of type Span

Modifier and Type	Method and Description
void	BooleanTag.set(Span span, Boolean tagValue)
void	IntTag.set(Span span, Integer tagValue)
void	StringTag.set(Span span, String tagValue)
void	IntOrStringTag.set(Span span, String tagValue)
void	StringTag.set(Span span, StringTag tag) Deprecated. as using the tag *key* as tag value is not usually required.
void	Tag.set(Span span, T value)
abstract void	AbstractTag.set(Span span, T tagValue)
