Detailed Description

Base class for theories.

Author: Clark Barrett

Created: Thu Jan 30 16:37:56 2003

This is an abstract class which all theories should inherit from. In addition to providing an abstract theory interface, it provides access functions to core functionality. However, in order to avoid duplicating the data structures which implement this functionality, all the functionality is stored in a separate class (which actually derives from this one) called TheoryCore. These two classes work closely together to provide the core functionality.

Constructor & Destructor Documentation

Theory::Theory

(

void

)

[private]

Private default constructor.

Everyone besides TheoryCore has to use the public constructor which sets up all the provided functionality automatically.

Definition at line 33 of file theory.cpp.

Theory::Theory	(	TheoryCore *	theoryCore,
		const std::string &	name
	)

Exposed constructor.

Note that each instance of Theory must have a name (mostly for debugging purposes).
