Method Summary

Modifier and Type	Method	Description
boolean	needsContext()	Indicates whether this factory requires an ApiTracerContext to be injected via ApiTracerFactory.withContext(ApiTracerContext) before creating tracers.
ApiTracer	newTracer(ApiTracer parent, ApiTracerContext tracerContext)	Create a new ApiTracer that will be a child of the current context.
ApiTracer	newTracer(ApiTracer parent, SpanName spanName, ApiTracerFactory.OperationType operationType)	Create a new ApiTracer that will be a child of the current context.
ApiTracerFactory	withContext(ApiTracerContext context)	Returns a new ApiTracerFactory that will use the provided context to infer attributes for all tracers created by the factory.

Method Details

newTracer

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

Description copied from class: BaseApiTracerFactory

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

Specified by:

newTracer in interface ApiTracerFactory

Overrides:

newTracer in class BaseApiTracerFactory

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 tracerContext)

Description copied from interface: ApiTracerFactory

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

Parameters:

parent - the parent of this tracer

tracerContext - 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.

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.

Parameters:

context - an ApiTracerContext object containing information to construct attributes
