Class DigesterFactory

java.lang.Object
com.lf.commons.lang.ManagedFactory
com.lf.digester.core.DigesterFactory
public class DigesterFactory extends com.lf.commons.lang.ManagedFactory
Factory class for vending various objects of the digester package.

Whenever possible, this factory will hand out references to shared instances. Use this if you need many, many objects of one single type while running your application and it is acceptable for you to continously use a certain amount of memory for the cached object. If you only use instances once then you should either install an object as usual (by calling new), or let this factory create a shared instance and flush the factory after you're finished with the object. The garbage collector will then release memory on-the-fly as the objects are no longer referenced so the overall memory footprint can be very small. You should keep the shared instances created by this class if you make heavy use of the supported classes (currently DigesterSettings).
