org.xeslite.lite.factory

Class XFactoryLiteImpl

java.lang.Object

org.xeslite.lite.factory.XFactoryLiteImpl

All Implemented Interfaces:

org.deckfour.xes.factory.XFactory

Direct Known Subclasses:

XFactoryLiteImpl

public class XFactoryLiteImpl
extends java.lang.Object
implements org.deckfour.xes.factory.XFactory

Creating lightweight XES objects with a smaller memory footprint than the original naive implementation. Attributes are stored in a fastutil OpenHashMap instead of the normal Java HashMap avoiding the overhead of having an Entry object for each attribute.

All attribute names and some literal values are de-duplicated using an Interner . We also use a simple sequential ID instead of a UUID. This saves approximately 16 bytes per event (8 byte for the object header and 8 byte for a long instead of two longs).
