Method Detail

addEvent

public void addEvent(RequestTraceSpan span)

Add a new event to the series being traced

Parameters:

span -

addEvent

public void addEvent(RequestTraceSpan span,
                     long timestampMillis)

endTrace

public void endTrace()

getElapsedTime

public long getElapsedTime()

Gets how long the trace took. If the trace has not finished then this will be 0.

Returns:

Time for trace in milliseconds

toString

public String toString()

Overrides:

toString in class Object

isStarted

public boolean isStarted()

Returns true if a trace has started. This will return true even if the trace has completed.

Returns:

getTraceSpans

public LinkedList<RequestTraceSpan> getTraceSpans()

Returns a list of all the events that make up the trace.

Returns:

A list containing all of the Spans that constitute this trace.

getStartTime

public Instant getStartTime()

Gets the Instant when the span was started See Instant.now() for how this time is generated.

Returns:

The Instant for when this span was started.

getEndTime

public Instant getEndTime()

Gets the end time of the request trace in milliseconds since the epoch (midnight, January 1st 1970).

This value is 0 until the request trace in finished.

Returns:

getTraceId

public UUID getTraceId()

Returns a unique identifier for the trace, which comes from the first event.

Returns:

null if no trace started

setTraceId

public void setTraceId(UUID newID)

isCompleted

public boolean isCompleted()

Returns true if a complete trace has finished

Returns:

addSpanLog

public void addSpanLog(RequestTraceSpanLog spanLog)

compareTo

public int compareTo(RequestTrace requestTrace)

Specified by:

compareTo in interface Comparable<RequestTrace>

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
