Span_Link class
A pointer from the current span to another span in the same trace or in a different trace. For example, this can be used in batching operations, where a single batch handler processes multiple requests from different traces or when the handler receives a request from a different project.

Properties
-
attributes
→ List<
KeyValue> -
attributes is a collection of attribute key/value pairs on the link.
Attribute keys MUST be unique (it is not allowed to have more than one
attribute with the same key).
no setter
- droppedAttributesCount ↔ int
-
dropped_attributes_count is the number of dropped attributes. If the value is 0,
then no attributes were dropped.
getter/setter pair
- eventPlugin → EventPlugin?
-
Subclasses can override this getter to be notified of changes
to protobuf fields.
no setterinherited
- flags ↔ int
-
Flags, a bit field. 8 least significant bits are the trace
flags as defined in W3C Trace Context specification. Readers
MUST not assume that 24 most significant bits will be zero.
When creating new spans, the most-significant 24-bits MUST be
zero. To read the 8-bit W3C trace flag (use flags &
SPAN_FLAGS_TRACE_FLAGS_MASK).
Optional.getter/setter pair - hashCode → int
-
Calculates a hash code based on the contents of the protobuf.
no setterinherited
- info_ → BuilderInfo
-
no setteroverride
- isFrozen → bool
-
Returns
trueif this message is marked read-only. Otherwisefalse.no setterinherited - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
spanId
↔ List<
int> -
A unique identifier for the linked span. The ID is an 8-byte array.
getter/setter pair
-
traceId
↔ List<
int> -
A unique identifier of a trace that this linked span is part of. The ID is a
16-byte array.
getter/setter pair
- traceState ↔ String
-
The trace_state associated with the link.
