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.

Definition at line 64 of file theory.h.

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
	)

Whether theory has been used (for smtlib translator)

Exposed constructor.

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

Definition at line 36 of file theory.cpp.

Theory::~Theory ( void ) [virtual]

Destructor.

Definition at line 44 of file theory.cpp.

Test if e is an i-leaf term for the current theory.

A term 'e' is an i-leaf for a theory 'i', if it is a variable, or 'e' belongs to a different theory. This definition makes sense for a larger term which by itself belongs to the current theory 'i', but (some of) its children are variables or belong to different theories.
