Detailed Description

Abstract base class for IPC key generators.

Each instance represents one IPC key generator.

Specific platforms dereive their implementation classes from this class.

The instances are created by LOW_IPCKeyGeneratorFactory, following the factory design pattern.

Note: There is no prescribed constructor.
