Class Factory

java.lang.Object
  ovm.polyd.Factory

public abstract class Factory
extends java.lang.Object

Used to create manually new instances of the desired dispatcher. Use a Factory to build dispatchers manually, rather than using annotations.

This class is not normally accessed directly, and it is of use only when using the pre-5.0 version of PolyD. To create a dispatcher manually, first create a Descriptor to specify all the characteristics of the desired dispatcher. When the Descriptor is registered, a Factory is generated, that can then be used to produce new dispatchers.

The bodies must be equal, in number and class, to the list supplied when building the Descriptor.
