Classes

Class Description
com.google.api.gax.tracing.BaseApiTracer A base implementation of ApiTracer that does nothing.

For internal use only.

com.google.api.gax.tracing.BaseApiTracerFactory Base factory that will build ApiTracers that do nothing.

For internal use only.

com.google.api.gax.tracing.OpencensusTracer Implementation of ApiTracer that uses OpenCensus.

This implementation wraps an OpenCensus Span for every tracer and annotates that Span with various events throughout the lifecycle of the logical operation.

com.google.api.gax.tracing.OpencensusTracerFactory A ApiTracerFactory to build instances of OpencensusTracer.

This class wraps the Tracer provided by Opencensus in Tracing.getTracer(). It will be used to create new spans and wrap them in OpencensusTracer defined in gax.

com.google.api.gax.tracing.SpanName A value class to represent the name of the operation in an ApiTracer.
com.google.api.gax.tracing.TracedBatchingCallable This callable wraps a batching callable chain in a ApiTracer.

For internal use only.

com.google.api.gax.tracing.TracedBidiCallable A wrapper callable that will wrap a callable chain in a trace.

For internal use only.

com.google.api.gax.tracing.TracedClientStreamingCallable A wrapper callable that will wrap a callable chain in a trace.

This can be safely called from multiple threads. However the request ApiStreamObserver can only be used from a single thread.

com.google.api.gax.tracing.TracedOperationCallable This callable wraps a OperationCallable in a ApiTracer.

For internal use only.

com.google.api.gax.tracing.TracedOperationInitialCallable Traces the initial RPC of a long running operation.

It will trace it like a child unary RPC and will also contribute to the parent tracer (created by TracedOperationCallable) the result of the call.

com.google.api.gax.tracing.TracedServerStreamingCallable A wrapper callable that will wrap a callable chain in a trace.

For internal use only.

com.google.api.gax.tracing.TracedUnaryCallable This callable wraps a callable chain in a ApiTracer.

For internal use only.

Interfaces

Interface Description
com.google.api.gax.tracing.ApiTracer Implementations of this class trace the logical flow of a google cloud client.

A single instance of a tracer represents a logical operation that can be annotated throughout its lifecycle. Constructing an instance of a subclass will implicitly signal the start of a new

com.google.api.gax.tracing.ApiTracer.Scope A context class to be used with #inScope() and a try-with-resources block. Closing a Scope removes any context that the underlying implementation might've set in #inScope().
com.google.api.gax.tracing.ApiTracerFactory A factory to create new instances of ApiTracers.

In general a single instance of an ApiTracer will correspond to a single logical operation.

Enums

Enum Description
com.google.api.gax.tracing.ApiTracerFactory.OperationType The type of operation the ApiTracer is tracing.
