类名称：Span
方法名：<init>

Span.<init>介绍

[英]The full constructor allowing you to set all fields representing a span's state. The traceId, spanId, and spanName fields cannot be null (an IllegalArgumentException will be thrown if any are null). This method is public to allow full flexibility, however in practice you should use one of the provided #generateRootSpanForNewTrace(String,SpanPurpose) or #generateChildSpan(String,SpanPurpose) helper methods, or the Builder if you need more flexibility than the helper methods. If you pass in null for spanPurpose then SpanPurpose#UNKNOWNwill be used.
WARNING: When deserializing a span that was initially started on a different JVM, you must pass in null for spanStartTimeNanos. Otherwise timing will be completely broken since System#nanoTime() is not comparable across JVMs.
[中]完整的构造函数，允许您设置表示跨度状态的所有字段。traceId、spanId和spanName字段不能为null（如果任何字段为null，将引发IllegalArgumentException）。此方法是公开的，以允许完全的灵活性，但是在实践中，您应该使用提供的#generateRootSpanForNewTrace（String，SpanPurpose）或#generateChildSpan（String，SpanPurpose）辅助方法之一，或者如果您需要比辅助方法更大的灵活性，可以使用生成器。如果您为spanPurpose输入null，则将使用spanPurpose#Unknown。
警告：当反序列化最初在不同JVM上启动的跨距时，您必须为spanStartTimeNanos传递null。否则，计时将完全中断，因为系统#nanoTime（）在JVM之间是不可比的。
