Interface IRendererFactory

All Known Implementing Classes:

ImageRendererFactory

public interface IRendererFactory

Produces renderer instances. Must be equal only to factory with same class. hashCode() must be implemented correctly aswell, to reflect this behaviour. In case of singleton factory, default Object's equals() and hashCode() is the correct implementation thus it is not needed to be overriden.
