Method Detail

extractEventTime

public long extractEventTime(TraceNode tn,
                    SpanEvent e)

Return the time stamp associated with a particular SpanEvent in this Trace Node. Return -1 if the TraceNode's Span did not contain that event.

getPreLinkTime

public long getPreLinkTime()

getPreLinkTimeString

public String getPreLinkTimeString()

Return pre-link time as a string.

getPostLinkTime

public long getPostLinkTime()

Return time delta between { @link SpanEvent.SERVER_SEND } and { @link SpanEvent.CLIENT_RECV }. This may be negative or zero in the case of clock skew.

getPostLinkTimeString

public String getPostLinkTimeString()

Return post-link time as a string.

getProcessTime

public long getProcessTime()

Return time delta between { @link SpanEvent.SERVER_RECV } and { @link SpanEvent.SERVER_SEND}.

getProcessTimeString

public String getProcessTimeString()

Return cpu time as a string.

getChildren

public List<TraceNode> getChildren()

Return the children of this node.
