All Classes

Class	Description
B3Propagation<K>	Implements B3 Propagation
B3SingleFormat	This format corresponds to the propagation key "b3" (or "B3"), which delimits fields in the following manner.
B3SinglePropagation<K>	Implements the propagation format described in B3SingleFormat.
BoundarySampler	This sampler is appropriate for high-traffic instrumentation (ex edge web servers that each receive >100K requests) who provision random trace ids, and make the sampling decision only once.
Clock	Epoch microseconds used for Span.timestamp() and Annotation.timestamp().
CorrelationFieldScopeDecorator	Adds correlation properties "traceId", "parentId", "spanId" and "sampled" when a span is current.
CountingSampler	This sampler is appropriate for low-traffic instrumentation (ex servers that each receive <100K requests), or those who do not provision random trace ids.
CurrentSpanCustomizer	Provides a mechanism for end users to be able to customise the current span.
CurrentTraceContext	This makes a given span the current span by placing it in scope (usually but not always a thread local scope).
CurrentTraceContext.Builder	Implementations of this allow standardized configuration, for example scope decoration.
CurrentTraceContext.Default	Default implementation which is backed by a static thread local.
CurrentTraceContext.Scope	A span remains in the scope it was bound to until close is called.
CurrentTraceContext.ScopeDecorator	Use this to add features such as thread checks or log correlation fields when a scope is created or closed.
CurrentTraceContextCustomizer	This allows configuration plugins to collaborate on building an instance of CurrentTraceContext.
DeclarativeSampler<M>	This is an implementation of how to decide whether to trace a request using annotations on a java method.
DeclarativeSampler.ProbabilityOfMethod<M>
DeclarativeSampler.RateForMethod<M>	Deprecated. since 5.8, use DeclarativeSampler.ProbabilityOfMethod
DeclarativeSampler.RateOfMethod<M>
ErrorParser	This is a simplified type used for parsing errors.
ExtraFactory<E>
ExtraFieldCustomizer	This allows configuration plugins to collaborate on building an instance of ExtraFieldPropagation.Factory.
ExtraFieldPropagation<K>	Allows you to propagate predefined request-scoped fields, usually but not always HTTP headers.
ExtraFieldPropagation.Factory
ExtraFieldPropagation.FactoryBuilder
FinishedSpanHandler	Triggered on each finished span except when spans that are no-op.
HexCodec
InternalPropagation	Escalate internal APIs in brave.propagation so they can be used from outside packages.
IpLiteral	Internal utility class to validate IPv4 or IPv6 literals
Lists
MapPropagationFields<K,V>	Copy-on-write keeps propagation changes in a child context from affecting its parent.
Matcher<P>	Returns true if this rule matches the input parameters
Matchers	Convenience functions to compose matchers for ParameterizedSampler.
MutableSpan	This represents a span except for its TraceContext.
MutableSpan.AnnotationConsumer<T>
MutableSpan.AnnotationUpdater
MutableSpan.TagConsumer<T>
MutableSpan.TagUpdater
MutableSpanConverter
NoopAwareFinishedSpanHandler	When noop, this drops input spans by returning false.
NoopSpanCustomizer	Performs no operations as the span represented by this is not sampled to report to the tracing system.
Nullable	Libraries such as Guice and AutoValue will process any annotation named Nullable.
ParameterizedSampler<P>	This is an implementation of how to decide whether to trace a request using ordered rules.
ParameterizedSampler.Builder<P>
ParameterizedSampler.Rule<P>	Deprecated. Since 5.8, use ParameterizedSampler.Builder.putRule(Matcher, Sampler)
PendingSpan
PendingSpans	Similar to Finagle's deadline span map, except this is GC pressure as opposed to timeout driven.
Platform	Access to platform-specific features.
PredefinedPropagationFields	Copy-on-write keeps propagation changes in a child context from affecting its parent
Propagation<K>	Injects and extracts trace identifiers as text into carriers that travel in-band across process boundaries.
Propagation.Factory
Propagation.Getter<C,K>	Gets the first value of the given propagation key or returns null
Propagation.KeyFactory<K>	Creates keys for use in propagated contexts
Propagation.Setter<C,K>	Replaces a propagated key with the given value
PropagationFields<K,V>	We need to retain propagation state extracted from headers.
PropagationFields.FieldConsumer<K,V>
PropagationFieldsFactory<K,V,P extends PropagationFields<K,V>>
RateLimitingSampler	The rate-limited sampler allows you to choose an amount of traces to accept on a per-second interval.
RecyclableBuffers
Sampler	Sampler is responsible for deciding if a particular trace should be "sampled", i.e.
SamplerFunction<T>	Decides whether to start a new trace based on request properties such as an HTTP path.
SamplerFunctions	Convenience sampling functions.
SamplingFlags
SamplingFlags.Builder	Deprecated. prefer using constants.
ScopedSpan	Used to model the latency of an operation within a method block.
Span	Used to model the latency of an operation.
Span.Kind
SpanCustomizer	Simple interface users can customize a span with.
StrictCurrentTraceContext	Deprecated. use StrictScopeDecorator.
StrictScopeDecorator	Useful when developing instrumentation as state is enforced more strictly.
ThreadLocalCurrentTraceContext	In-process trace context propagation backed by a static thread local.
ThreadLocalSpan	This type allows you to place a span in scope in one method and access it in another without using an explicit request parameter.
TraceContext	Contains trace identifiers and sampling data propagated in and out-of-process.
TraceContext.Builder
TraceContext.Extractor<C>	Used to continue an incoming trace.
TraceContext.Injector<C>	Used to send the trace context downstream.
TraceContextOrSamplingFlags	Union type that contains only one of trace context, trace ID context or sampling flags.
TraceContextOrSamplingFlags.Builder
TraceIdContext	Contains inbound trace ID and sampling flags, used when users control the root trace ID, but not the span ID (ex Amazon X-Ray or other correlation).
TraceIdContext.Builder
Tracer	Using a tracer, you can create a root span capturing the critical path of a request.
Tracer.SpanInScope	A span remains in the scope it was bound to until close is called.
Tracing	This provides utilities needed for trace instrumentation.
Tracing.Builder
TracingCustomizer	This allows configuration plugins to collaborate on building an instance of Tracing.
WrappingExecutorService	Used to implement a context propagating executor service which wraps tasks
ZipkinFinishedSpanHandler	logs exceptions instead of raising an error, as the supplied reporter could have bugs
