Notify theory of a new shared term. When a term e associated with theory i occurs as a child of an expression associated with theory j, the framework calls i>addSharedTerm(e) and j>addSharedTerm(e) Reimplemented from CVCL::Theory. Definition at line 80 of file theory_array.h. 

Assert a new fact to the decision procedure. Each fact that makes it into the core framework is assigned to exactly one theory: the theory associated with that fact. assertFact is called to inform the theory that a new fact has been assigned to the theory. Implements CVCL::Theory. Definition at line 81 of file theory_array.h. 

Check for satisfiability in the theory.
Implements CVCL::Theory. Definition at line 82 of file theory_array.h. 

Theoryspecific rewrite rules. By default, rewrite just returns a reflexive theorem stating that the input expression is equivalent to itself. However, rewrite is allowed to return any theorem which describes how the input expression is equivalent to some new expression. rewrite should be used to perform simplifications, normalization, and any other preprocessing on theoryspecific expressions that needs to be done.

Set up the term e for callbacks when e or its children change. setup is called once for each expression associated with the theory. It is typically used to setup theoryspecific data for an expression and to add callback information for use with update.

Notify a theory of a new equality. update is a callback used by the notify mechanism of the core theory. It works as follows. When an equation t1 = t2 makes it into the core framework, the two find equivalence classes for t1 and t2 are merged. The result is that t2 is the new equivalence class representative and t1 is no longer an equivalence class representative. When this happens, the notify list of t1 is traversed. Notify list entries consist of a theory and an expression d. For each entry (i,d), i>update(e, d) is called, where e is the theorem corresponding to the equality t1=t2. To add the entry (i,d) to a term t1's notify list, a call must be made to t1.addNotify(i,d). This is typically done in setup.

An optional solver. The solve method can be used to implement a Shostakstyle solver. Since solvers do not in general combine, the following technique is used. One theory is designated as the primary solver (in our case, it is the theory of arithmetic). For each equation that enters the core framework, the primary solver is called to ensure that the equation is in solved form with respect to the primary theory. After the primary solver, the solver for the theory associated with the equation is called. This solver can do whatever it likes, as long as the result is still in solved form with respect to the primary solver. This is a slight generalization of what is described in my (Clark)'s PhD thesis. Reimplemented from CVCL::Theory.

Theoryspecific prettyprinting. By default, print the top node in AST, and resume prettyprinting the children. The same call e.print(os) can be used in DPspecific printers to use AST printing for the given node. In fact, it is strongly recommended to add e.print(os) as the default for all the cases/kinds that are not handled by the particular prettyprinter. Reimplemented from CVCL::Theory.
