Theorem TheoryRecords::rewriteAux ( const Expr &  e) [private]

Auxiliary rewrites: Processing of AND and OR of equations. Returns e=e'.

When a record/tuple (dis)equality is expanded into the (dis)equalities of fields, we have to perform rewrites on the resulting record terms before the simplifier kicks in.

Otherwise, if we have r1.f = r2.f, but r1=r2 was asserted before, for some complex record expressions r1 and r2, then the simplifier will substitute r2 for r1, and we get r2.f=r2.f at the end, which is not a useful fact to have.

However, r1.f and/or r2.f may rewrite to something interesting, and the equality may yield new important facts.

Cardinality TheoryRecords::finiteTypeInfo ( Expr &  e,
Unsigned &  n,
bool  enumerate,
bool  computeSize 
) [virtual]

Compute information related to finiteness of types.

Used by the TypeComputer defined in TheoryCore (theories should not call this funtion directly -- they should use the methods in Type instead). Each theory should implement this if it contains any types that could be non-infinite.

1. Returns Cardinality of the type (finite, infinite, or unknown) 2. If cardinality = finite and enumerate is true, sets e to the nth element of the type if it can sets e to NULL if n is out of bounds or if unable to compute nth element 3. If cardinality = finite and computeSize is true, sets n to the size of the type if it can sets n to 0 otherwise

Expr TheoryRecords::computeTypePred ( const Type &  t,
const Expr &  e 
) [virtual]

Theory specific computation of the subtyping predicate for type t applied to the expression e.

By default returns true. Each theory needs to compute subtype predicates for the types associated with it. So, for example, the theory of records will take a record type [# f1: T1, f2: T2 #] and an expression e and will return the subtyping predicate for e, namely: computeTypePred(T1, e.f1) AND computeTypePred(T2, e.f2)

void TheoryRecords::computeModelTerm ( const Expr &  e,
std::vector< Expr > &  v 
) [virtual]

Add variables from 'e' to 'v' for constructing a concrete model.

If e is already of primitive type, do NOT add it to v.

void TheoryRecords::computeModel ( const Expr &  e,
std::vector< Expr > &  vars 
) [virtual]

Compute the value of a compound variable from the more primitive ones.

The more primitive variables for e are already assigned concrete values, and are available through getModelValue().

The new value for e must be assigned using assignValue() method.

Parameters:
eis the compound type expression to assign a value;
varsare the variables actually assigned. Normally, 'e' is the only element of vars. However, e.g. in the case of uninterpreted functions, assigning 'f' means assigning all relevant applications of 'f' to constant values (f(0), f(5), etc.). Such applications might not be known before the model is constructed (they may be of the form f(x), f(y+z), etc., where x,y,z are still unassigned).

Populating 'vars' is an opportunity for a DP to change the set of top-level "variables" to assign, if needed. In particular, it may drop 'e' from the model entirely, if it is already a concrete value by itself.

Expr TheoryRecords::computeTCC ( const Expr &  e) [virtual]

Compute and cache the TCC of e.

Parameters:
eis an expression (term or formula). This function computes the TCC of e which is true iff the expression is defined.

This function computes the TCC or predicate of the top-level operator of e, and recurses into children using getTCC(), if necessary.

The default implementation is to compute TCCs recursively for all children, and return their conjunction.

void TheoryRecords::setup ( const Expr &  e) [virtual]

Set up the term e for call-backs when e or its children change.

setup is called once for each expression associated with the theory. It is typically used to setup theory-specific data for an expression and to add call-back information for use with update.

void TheoryRecords::update ( const Theorem &  e,
const Expr &  d 
) [virtual]

Notify a theory of a new equality.

update is a call-back 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.
