Query the persistence obtaining a Map where the date is the key and the #Info is the value. The result is relative to an Usage Record Type, respect a TemporalConstraint and can be applied one or more filters.

Parameters:

clz - the Record Class of interest

temporalConstraint - the TemporalConstraint (interval and aggregation)

filters - list of filter to obtain the time series. If null or empty list get all data for the interested Record Class with the applying temporal constraint. All Filter must have not null and not empty key and value. The filters are must be related to different keys and are in AND. If the list contains more than one filter with the same key an Exception is thrown.

Returns:

the Map containing for each date in the required interval the requested data

Throws:

DuplicatedKeyFilterException

KeyException

ValueException

Exception

Return a SortedMap containing the TimeSeries for top values for a certain key taking in account all Filters. The key is identified adding a Filter with a null value. Only one Filter with null value is allowed otherwise an Exception is thrown. The values are ordered from the most occurred value.

Parameters:

clz - the Usage Record Class of interest

temporalConstraint - the TemporalConstraint (interval and aggregation)

filters - list of filter to obtain the time series of top values. If null or empty list get all data for the interested Record Class with the applying temporal constraint. All Filter must have not null and not empty key and value. The filters are must be related to different keys and are in AND. If the list contains more than one filter with the same key an Exception is thrown.
