Golang IteratorOptions.SeekTime Examples

Example #1

File: iterator_test.go Project: seiflotfy/influxdb

func TestIteratorOptions_SeekTime_Descending(t *testing.T) {
	opt := influxql.IteratorOptions{
		StartTime: 30,
		EndTime:   60,
		Ascending: false,
	}

	time := opt.SeekTime()
	if time != 60 {
		t.Errorf("expected time to be 60, got %d", time)
	}
}

Example #2

File: engine.go Project: li-ang/influxdb

// buildBooleanCursor creates a cursor for a boolean field.
func (e *Engine) buildBooleanCursor(measurement, seriesKey, field string, opt influxql.IteratorOptions) booleanCursor {
	cacheValues := e.Cache.Values(SeriesFieldKey(seriesKey, field))
	keyCursor := e.KeyCursor(SeriesFieldKey(seriesKey, field), opt.SeekTime(), opt.Ascending)
	return newBooleanCursor(opt.SeekTime(), opt.Ascending, cacheValues, keyCursor)
}

Example #3

File: engine.go Project: rwarren/influxdb

// buildIntegerCursor creates a cursor for an integer field.
func (e *Engine) buildIntegerCursor(measurement, seriesKey, field string, opt influxql.IteratorOptions) integerCursor {
	cacheValues := e.Cache.Values(SeriesFieldKey(seriesKey, field))
	keyCursor := e.KeyCursor(SeriesFieldKey(seriesKey, field), time.Unix(0, opt.SeekTime()).UTC(), opt.Ascending)
	return newIntegerCursor(opt.SeekTime(), opt.Ascending, cacheValues, keyCursor)
}
