public class TLcyCompositeOutputStreamFactory extends TLcyGenericComposite<ILcdOutputStreamFactory> implements ILcdOutputStreamFactory
Composite implementation (see composite design pattern) of ILcdOutputStreamFactory.
You can use the TLcyCompositeOutputStreamFactory in two ways:
ILcyLucyEnv:
ILcdOutputStreamFactory
services registered in the Lucy back-end until one succeeds.
TLcyCompositeOutputStreamFactorys will add and remove the
factory as a service in the Lucy back-end.
ILcyLucyEnv:
ILcdOutputStreamFactory
registered in this instance until one succeeds.
TLcyCompositeOutputStreamFactorys will only be performed
on this instance.
You can also loop over the underlying ILcdOutputStreamFactorys yourself using the
standard iterator.
