## Description

Base class for the host processor interface.

:Implemented by the Plug-In:

Note
  This class always inherits from the latest version of the interface and thus requires any subclass to implement all the methods in the latest version of the interface. Most plug-ins will inherit from the AAX_CHostProcessor convenience class.
