function SpanInterface::addLink

Records a link to another `SpanContext`.

Adding links at span creation via {@link SpanBuilderInterface::addLink()} is preferred to calling {@link SpanInterface::addLink()} later, for contexts that are available during span creation, because head sampling decisions can only consider information present during span creation.

Parameters

SpanContextInterface $context span context to link:

iterable $attributes attributes to associate with the link:

Return value

SpanInterface this span
