Uses of Nullable in brave

Methods in brave with annotations of type Nullable

Modifier and Type	Method	Description
static Tracing	Tracing.current()	Returns the most recently created tracing component iff it hasn't been closed.
Span	Tracer.currentSpan()	Returns the current span in scope or null if there isn't one.
static Tracer	Tracing.currentTracer()	Returns the most recently created tracer if its component hasn't been closed.

Method parameters in brave with annotations of type Nullable

Modifier and Type	Method	Description
ScopedSpan	Tracer.startScopedSpanWithParent(String name, TraceContext parent)	Same as Tracer.startScopedSpan(String), except ignores the current trace context.
Tracer.SpanInScope	Tracer.withSpanInScope(Span span)	Makes the given span the "current span" and returns an object that exits that scope on close.

Uses of Nullable in brave.propagation

Methods in brave.propagation with annotations of type Nullable

Modifier and Type	Method	Description
TraceContext	TraceContextOrSamplingFlags.context()
static String	ExtraFieldPropagation.current(String name)	Synonym for ExtraFieldPropagation.get(String)
abstract TraceContext	CurrentTraceContext.get()	Returns the current span in scope or null if there isn't one.
static String	ExtraFieldPropagation.get(TraceContext context, String name)	Returns the value of the field with the specified key or null if not available
static String	ExtraFieldPropagation.get(String name)	Returns the value of the field with the specified key or null if not available.
String	Propagation.Getter.get(C carrier, K key)
Span	ThreadLocalSpan.next()	Returns the Tracer.nextSpan() or null if ThreadLocalSpan.CURRENT_TRACER and tracing isn't available.
Span	ThreadLocalSpan.next(TraceContextOrSamplingFlags extracted)	Returns the Tracer.nextSpan(TraceContextOrSamplingFlags) or null if ThreadLocalSpan.CURRENT_TRACER and tracing isn't available.
Long	TraceContext.parentId()	The parent's TraceContext.spanId or null if this the root span in a trace.
Span	ThreadLocalSpan.remove()	Returns the span set in scope via ThreadLocalSpan.next() or null if there was none.
abstract Boolean	SamplingFlags.sampled()	Should we sample this request or not? True means sample, false means don't, null means we defer decision to someone further down in the stack.
Boolean	TraceContext.sampled()	Should we sample this request or not? True means sample, false means don't, null means we defer decision to someone further down in the stack.
Boolean	TraceContextOrSamplingFlags.sampled()	Returns SamplingFlags.sampled(), regardless of subtype.
Boolean	TraceIdContext.sampled()	Should we sample this request or not? True means sample, false means don't, null means we defer decision to someone further down in the stack.
SamplingFlags	TraceContextOrSamplingFlags.samplingFlags()
TraceIdContext	TraceContextOrSamplingFlags.traceIdContext()

Method parameters in brave.propagation with annotations of type Nullable

Modifier and Type	Method	Description
static SamplingFlags	SamplingFlags.Builder.build(Boolean sampled)	Allows you to create flags from a boolean value without allocating a builder instance
CurrentTraceContext.Scope	CurrentTraceContext.maybeScope(TraceContext currentSpan)	Like CurrentTraceContext.newScope(TraceContext), except returns CurrentTraceContext.Scope.NOOP if the given context is already in scope.
CurrentTraceContext.Scope	CurrentTraceContext.Default.newScope(TraceContext currentSpan)
abstract CurrentTraceContext.Scope	CurrentTraceContext.newScope(TraceContext currentSpan)	Sets the current span in scope until the returned object is closed.
CurrentTraceContext.Scope	StrictCurrentTraceContext.newScope(TraceContext currentSpan)	Identifies problems by throwing assertion errors when a scope is closed on a different thread.
TraceContext.Builder	TraceContext.Builder.parentId(Long parentId)
SamplingFlags.Builder	SamplingFlags.Builder.sampled(Boolean sampled)
TraceContext.Builder	TraceContext.Builder.sampled(Boolean sampled)
TraceContextOrSamplingFlags	TraceContextOrSamplingFlags.sampled(Boolean sampled)
TraceIdContext.Builder	TraceIdContext.Builder.sampled(Boolean sampled)
