Class SpanContextImpl

java.lang.Object

rocks.inspectit.agent.java.sdk.opentracing.internal.impl.SpanContextImpl

All Implemented Interfaces:

io.opentracing.SpanContext

public class SpanContextImpl
extends java.lang.Object
implements io.opentracing.SpanContext

Implementation of the SpanContext. Keeps information about span id, trace id and span parent id. Sampling flag is not included in the moment as it's not explicitly defined by the opentracing API.

Constructor Detail

SpanContextImpl

public SpanContextImpl(long id,
                       long traceId,
                       long parentId,
                       java.lang.String referenceType,
                       java.util.Map<java.lang.String,java.lang.String> baggage)

Constructor. Use build methods.

Parameters:

id - Unique ID of the span.

traceId - ID of the trace that span belongs to.

parentId - ID of the span's parent.

referenceType - Reference to the parent.

baggage - Additional baggage

Method Detail

build

public static SpanContextImpl build(SpanContextImpl parent,
                                    java.lang.String referenceType,
                                    java.util.Map<java.lang.String,java.lang.String> baggage)

Builds new SpanContextImpl as a child of given parent context. If parent context is null then build(Map) will be used and new trace context will be created.

Passed baggage will be the baggage of this span context.

Parameters:

parent - Context that will be use to determine to which trace/parent new context belongs. Can be null to denote that the new trace context should be created.

referenceType - Reference type to the parent context.

baggage - Context baggage.

Returns:

SpanContextImpl. Never null.

build

public static SpanContextImpl build(java.util.Map<java.lang.String,java.lang.String> baggage)

Builds new SpanContextImpl with new trace context and given baggage.

Parameters:

baggage - Context baggage.

Returns:

SpanContextImpl. Never null.

build

public static SpanContextImpl build()

Builds new SpanContextImpl with new trace context and no baggage.

Returns:

SpanContextImpl. Never null.

buildExtractedContext

public static SpanContextImpl buildExtractedContext(long passedId,
                                                    long passedTraceId,
                                                    java.util.Map<java.lang.String,java.lang.String> passedBaggage)

This method is used when building context that is extracted from the propagation (like HTTP headers). In this only calling span id and trace id are passed over the network with the baggage. Returned context represents the context of the calling span.

Parameters:

passedId - calling span id

passedTraceId - calling span trace id

passedBaggage - passage traveling along

Returns:

Context representing the context of the calling span.
