Example 3 with SpanContext

use of io.opencensus.trace.SpanContext in project instrumentation-java by census-instrumentation.

the class HttpClientHandler method handleStart.

/**
 * Instrument a request for tracing and stats before it is sent.

 * span will be serialized and propagated to the server.
 *
 * <p>The generated span will NOT be set as current context. User can control when to enter the
 * scope of this span. Use {@link AbstractHttpHandler#getSpanFromContext} to retrieve the span.
 *
 * @param parent the parent {@link Span}. {@code null} indicates using current span.
 * @param carrier the entity that holds the HTTP information.
 * @param request the request entity.
 * @return the {@link HttpRequestContext} that contains stats and trace data associated with the
 *     request.
