- Method Detail
  - handleSampledHeaders
```
 abstract HttpRequestInfoBuilder handleSampledHeaders(HttpRequestInfoBuilder requestInfoBuilder, DatadogTracer tracer, DatadogSpan span)
```
    Handles HTTP header injection for sampled requests. This method is called when a request has been sampled and trace context headers should be injected to propagate the trace to downstream services.
    
    Parameters:
    
    requestInfoBuilder - the modifier to use for adding headers to the request.
    
    tracer - the tracer instance used for context propagation.
    
    span - the span associated with this request.
  - handleNotSampledHeaders
```
 abstract HttpRequestInfoBuilder handleNotSampledHeaders(HttpRequestInfoBuilder requestInfoBuilder, DatadogTracer tracer, DatadogSpan span)
```
    Handles HTTP header injection for non-sampled requests. This method is called when a request has not been sampled. Depending on the trace context injection strategy, headers may or may not be injected.
    
    Parameters:
    
    requestInfoBuilder - the modifier to use for adding headers to the request.
    
    tracer - the tracer instance used for context propagation.
    
    span - the span associated with this request.
