Method Details

newTracer

public ApiTracer newTracer(ApiTracer parent,
 SpanName spanName,
 ApiTracerFactory.OperationType operationType)

Description copied from interface: ApiTracerFactory

Create a new ApiTracer that will be a child of the current context.

Specified by:

newTracer in interface ApiTracerFactory

Parameters:

parent - the parent of this tracer

spanName - the name of the new span

operationType - the type of operation that the tracer will trace

newTracer

public ApiTracer newTracer(ApiTracer parent,
 ApiTracerContext methodLevelTracerContext)

Description copied from interface: ApiTracerFactory

Create a new ApiTracer that will be a child of the current context.

Specified by:

newTracer in interface ApiTracerFactory

Parameters:

parent - the parent of this tracer

methodLevelTracerContext - the method-definition-specific tracer context

needsContext

public boolean needsContext()

Description copied from interface: ApiTracerFactory

Indicates whether this factory requires an ApiTracerContext to be injected via ApiTracerFactory.withContext(ApiTracerContext) before creating tracers.

Specified by:

needsContext in interface ApiTracerFactory

Returns:

true if an ApiTracerContext should be injected, false otherwise.

withContext

public ApiTracerFactory withContext(ApiTracerContext context)

Description copied from interface: ApiTracerFactory

Returns a new ApiTracerFactory that will use the provided context to infer attributes for all tracers created by the factory.

Specified by:

withContext in interface ApiTracerFactory

Parameters:

context - an ApiTracerContext object containing information to construct attributes
