C# Class FiftyOne.Foundation.Mobile.Detection.Factories.StreamFactory

Factory class used to create a DataSet from a source data structure. All the entities are held in the persistent store and only loads into memory when required. A cache mechanisim is used to improve efficiency as many entities are frequently used in a high volume environment.

The data set will be initialised very quickly as only the header information is read. Entities are then created when requested by the detection process and stored in a cache to avoid being recreated if their requested again after a short period of time.

A dataset can be created in several ways: Using a data file: DataSet dataSet = StreamFactory.Create("path_to_file", false);

Where the boolean flag indicates if the data file should or should not be deleted when close() is invoked.

Using a byte array: DataSet dataSet = StreamFactory.Create(dataFileAsByteArray);

Where the byte array is the 51Degrees device data file read into a byte array.

The very small data structures , Properties and Components are always stored in memory as there is no benefit retrieving them every time they're needed.
