Class StreamFactory

java.lang.Object
  fiftyone.mobile.detection.factories.StreamFactory

public final class StreamFactory
extends Object

Factory class used to create a DetectorDataSet from a source data structure. All the entities are held in the persistent store and only loads into memory when required. A cache mechanism 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.

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