public final class TraceSpan extends GeneratedMessageV3 implements TraceSpanOrBuilder
A span represents a single timed event within a trace. Spans can be nested
and form a trace tree. Often, a trace contains a root span that describes the
end-to-end latency of an operation and, optionally, one or more subspans for
its suboperations. Spans do not need to be contiguous. There may be gaps
between spans in a trace.

Methods
public boolean containsLabels(String key)
Collection of labels associated with the span. Label keys must be less than
128 bytes. Label values must be less than 16 kilobytes (10MB for
/stacktrace values).
Some predefined label keys exist, or you may create your own. When creating
your own, we recommend the following formats:
map<string, string> labels = 7;

Overrides
public TraceSpan getDefaultInstanceForType()
public Timestamp getEndTime()
End time of the span in nanoseconds from the UNIX epoch.
.google.protobuf.Timestamp end_time = 5;
public TimestampOrBuilder getEndTimeOrBuilder()
End time of the span in nanoseconds from the UNIX epoch.
.google.protobuf.Timestamp end_time = 5;
public TraceSpan.SpanKind getKind()
Distinguishes between spans generated in a particular context. For example,
two spans with the same name may be distinguished using RPC_CLIENT
and RPC_SERVER to identify queueing latency associated with the span.
.google.devtools.cloudtrace.v1.TraceSpan.SpanKind kind = 2;
public int getKindValue()
Distinguishes between spans generated in a particular context. For example,
two spans with the same name may be distinguished using RPC_CLIENT
and RPC_SERVER to identify queueing latency associated with the span.
.google.devtools.cloudtrace.v1.TraceSpan.SpanKind kind = 2;
| Returns |
|---|
| Type | Description |
int | The enum numeric value on the wire for kind.
|
public Map<String,String> getLabels()
public int getLabelsCount()
Collection of labels associated with the span. Label keys must be less than
128 bytes. Label values must be less than 16 kilobytes (10MB for
/stacktrace values).
Some predefined label keys exist, or you may create your own. When creating

public Map<String,String> getLabelsMap()
Collection of labels associated with the span. Label keys must be less than

public String getLabelsOrDefault(String key, String defaultValue)
Collection of labels associated with the span. Label keys must be less than
128 bytes. Label values must be less than 16 kilobytes (10MB for
/stacktrace values).
Some predefined label keys exist, or you may create your own. When creating

| Parameter |
|---|
| Name | Description |
key | String
|
Name of the span. Must be less than 128 bytes. The span name is sanitized
and displayed in the Stackdriver Trace tool in the
Google Cloud Platform Console.
The name may be a method name or some other per-call site name.
For the same executable and the same call point, a best practice is
to use a consistent name, which makes it easier to correlate
cross-trace spans.
string name = 3;
| Returns |
|---|
| Type | Description |
String | The name.
|
public ByteString getNameBytes()
Name of the span. Must be less than 128 bytes. The span name is sanitized
and displayed in the Stackdriver Trace tool in the
Google Cloud Platform Console.
The name may be a method name or some other per-call site name.
For the same executable and the same call point, a best practice is
to use a consistent name, which makes it easier to correlate
cross-trace spans.
string name = 3;
| Returns |
|---|
| Type | Description |
ByteString | The bytes for name.
|
public long getParentSpanId()
Optional. ID of the parent span, if any.
fixed64 parent_span_id = 6 [(.google.api.field_behavior) = OPTIONAL];
| Returns |
|---|
| Type | Description |
long | The parentSpanId.
