包路径：io.opencensus.trace.Tracer
类名称：Tracer
方法名：spanBuilderWithExplicitParent

Tracer.spanBuilderWithExplicitParent介绍

[英]Returns a SpanBuilder to create and start a new child Span (or root if parent is null or has an invalid SpanContext), with parent being the designated Span.

See SpanBuilder for usage examples.

This must be used to create a Span when manual Context propagation is used OR when creating a root Span with a null parent.
[中]返回一个SpanBuilder，以创建并启动一个新的子跨度（如果父跨度为null或具有无效的SpanContext，则返回root），父跨度为指定的跨度。
有关用法示例，请参见SpanBuilder。
当使用手动上下文传播或使用空父级创建根范围时，必须使用此选项来创建范围。
