TraceContext

public TraceContext(APMSpan topSpan,
                    NodeBuilder rootNode,
                    TraceReporter reporter)

This constructor initialises the trace context.

Parameters:

topSpan - The top level span in the trace

rootNode - The builder for the root node of the trace fragment

reporter - The trace reporter

Method Detail

startProcessingNode

public void startProcessingNode()

This method indicates the start of processing a node within the trace instance.

transaction - the transaction to set

getReportingLevel

public String getReportingLevel()

Returns:

the reportingLevel

setReportingLevel

public void setReportingLevel(String reportingLevel)

Parameters:

reportingLevel - the reportingLevel to set

getNodeProcessors

public List<NodeProcessor> getNodeProcessors()

This method returns the node processors.

Returns:

The node processors

getTopSpan

public APMSpan getTopSpan()

This method returns the top span associated with the traces involved in the current service invocation.

Returns:

The top span

getSourceEndpoint

public EndpointRef getSourceEndpoint()

This method returns the source endpoint for the root trace fragment generated by the service invocation.
