Class Summary
DataCache An instance of this class caches datasets previously read from a data file in memory.
DataSeries Repsesents a data series inside the cache; stores all series specific information and provides convenience methods for accessing that information.
DataSet This class defines a dataset and encapsulates related data; a dataset holds one data value for each of the data series held in the cache and corresponds to a data row in the underlying data file.
DataStreamToCacheReader This reader will parse a data stream using DataStreamReader and store all information in a data cache for further processing by the application.

See DataStreamWriter for the details of the data file format.
UpdateInvoker An object of this class is used to triger updates from a data input stream into a DataCache at regular intervals.
 

Enum Summary

DataCache.CacheMode Defines possible cache modes.
DataSet.DefRetValue Possible default return values; a default return value is used when a dataset is queried for a value at an invalid index or when the index was valid, but corresponding value in the underlying data file could not be interpreted as a legal data value.
