Class Summary

Class	Description
AlwaysSampler	A Sampler that always returns true.
CountSampler	Sampler that returns true every N calls.
HTraceConfiguration	Wrapper which integrating applications should implement in order to provide tracing configuration.
LocalFileSpanReceiver	Writes the spans it receives to a local file.
MilliSpan	A Span implementation that stores its information in milliseconds since the epoch.
MilliSpan.Builder	The public interface for constructing a MilliSpan.
MilliSpan.MilliSpanDeserializer
NeverSampler	A Sampler that never returns true.
POJOSpanReceiver	SpanReceiver for testing only that just collects the Span objects it receives.
ProbabilitySampler	Sampler that returns true a certain percentage of the time.
Sampler	Extremely simple callback to determine the frequency that an action should be performed.
Sampler.Builder	A Sampler builder.
Span.SpanSerializer
SpanId	Uniquely identifies an HTrace span.
SpanReceiver	The collector within a process that is the destination of Spans when a trace is running.
SpanReceiver.Builder	A SpanReceiver builder.
StandardOutSpanReceiver	Used for testing.

TraceCallable<V>	Wrap a Callable with a Span that survives a change in threads.
TraceExecutorService
Tracer	Use a Tracer instance inside a 'process' to collect and distribute its trace Spans.
Tracer.Builder
TracerId	The HTrace tracer ID. HTrace tracer IDs are created from format strings.
