示例1: GetData
/// <summary>
/// Retrieves or generates the appropriate ComponentData object from the historical and current QueryContexts in <paramref name="queryHistory"/>
/// </summary>
/// <param name="queryHistory">A FIFO array of QueryContexts representing the current and historical query data, most recent query is last position</param>
/// <returns></returns>
public static ComponentData GetData(IQueryContext[] queryHistory)
{
if (!queryHistory.Any())
{
return null;
}
var queryName = queryHistory.First().QueryName;
if (queryHistory.Any(qh => qh.QueryName != queryName))
{
throw new ArgumentException("GetData can only process history for one query at a time!");
}
var mostRecentUnsentQuery = queryHistory.LastOrDefault(q => !q.DataSent);
//If nothing to send, return null
if (mostRecentUnsentQuery == null)
{
return null;
}
//If the query metric should be a Delta (differential, generate ComponentData based on passed in history
if (mostRecentUnsentQuery.MetricTransformEnum == MetricTransformEnum.Delta)
{
//For first encounter, send empty metric
if (queryHistory.Length == 1)
{

//Get Previous Query

}
//Otherwise, just return latest unsent
