SimpleQueryRecord.PartialResult.TraceStep
public SimpleQueryRecord.PartialResult.TraceStep(Filter filter)
- Construct a TraceStep
- Parameters:
filter
- the step filter
recordPostFilterKeys
public void recordPostFilterKeys(int nSizeOut)
- Record the number of keys remaining after filter evaluation. This method may be called repeatedly on the same step instance during the scan phase of a query trace plan operation. Each call will add to the total recorded post-evaluation key set size for this step.
During the scan phase of a query trace plan operation, each entry is evaluated against the filter individually. Each call to trace
should record a key set count of 1
and a result key set count of fResult ? 1 : 0
where fResult
is the result of a call to EntryFilter.evaluateEntry(Map.Entry)
.
-
- Specified by:
recordPostFilterKeys
in interface QueryRecord.PartialResult.TraceStep
-
- Parameters:
nSizeOut
- the number of keys remaining after filter evaluation
recordDuration
public void recordDuration(long cMillisElapsed)
- Record the time spent evaluating the filter or applying an index. This method may be called repeatedly on the same step instance during the scan phase of a query trace plan operation. Calling this method repeatedly will add to the total duration recorded for this step.
-
- Specified by:
recordDuration
in interface QueryRecord.PartialResult.TraceStep
-
- Parameters:
cMillisElapsed
- the number of milliseconds spent evaluating the filter
ensureStep
public QueryRecord.PartialResult.TraceStep ensureStep(Filter filter)
- Ensure an inner nested trace step for the given filter. If there is no inner nested step associated with the given filter then a new step is created.
-
- Specified by:
ensureStep
in interface QueryRecord.PartialResult.TraceStep
-
- Parameters:
filter
- the filter to associate the new step with
- Returns:
- the inner nested step associated with the given filter
