makeVariable
public BooleanFormula makeVariable(String pVar)
Description copied from interface:BooleanFormulaManagerCreates a variable with exactly the given name.Please make sure that the given name is valid in SMT-LIB2. Take a look at
FormulaManager.isValidName(java.lang.String)for further information.This method does not quote or unquote the given name, but uses the plain name "AS IS".
Formula.toString()can return a different String than the given one.- Specified by:

public final boolean isTrue(BooleanFormula pBits)
Description copied from interface:BooleanFormulaManagerCheck, if the formula is the formula "TRUE". This does not include a satisfiability check, but only a syntactical matching. However, depending on the SMT solver, there might be some pre-processing of formulas such that trivial cases like "1==1" are recognized and rewritten as "TRUE", and thus such formulas might also be matched.- Specified by:

Description copied from interface:BooleanFormulaManagerCheck, if the formula is the formula "FALSE". This does not include a satisfiability check, but only a syntactical matching. However, depending on the SMT solver, there might be some pre-processing of formulas such that trivial cases like "1==2" are recognized and rewritten as "FALSE", and thus such formulas might also be matched.- Specified by:

public void visitRecursively(BooleanFormula pF, BooleanFormulaVisitor<TraversalProcess> pFormulaVisitor)
Description copied from interface:BooleanFormulaManagerVisit the formula recursively with a givenBooleanFormulaVisitor.This method guarantees that the traversal is done iteratively, without using Java recursion, and thus is not prone to StackOverflowErrors.
Furthermore, this method also guarantees that every equal part of the formula is visited only once. Thus, it can be used to traverse DAG-like formulas efficiently.

-
transformRecursively
public BooleanFormula transformRecursively(BooleanFormula f, BooleanFormulaTransformationVisitor pVisitor)
Description copied from interface:BooleanFormulaManagerVisit the formula recursively with a givenBooleanFormulaVisitor. The arguments each visitor method receives are already transformed.This method guarantees that the traversal is done iteratively, without using Java recursion, and thus is not prone to StackOverflowErrors.
Furthermore, this method also guarantees that every equal part of the formula is visited only once. Thus, it can be used to traverse DAG-like formulas efficiently.
