- All Implemented Interfaces:
- java.io.Serializable
public final class TrivialFormulaException
- extends java.lang.Exception
Thrown when a reduction is found to be trivially (un)satisfiable
with respect to given Bounds.

TrivialFormulaException
public TrivialFormulaException(Formula reduction,
BooleanConstant formulaValue,
Bounds bounds,
java.util.Map<Decl,Relation> skolems)
- Constructs a new TrivialFormulaException caused by the specified reduction.
That is, the reduction has caused its parent reduction
to simplify to the given value when translated using the given Bounds.
- effects:
this.reduction' = reduction && this.bounds' = bounds && this.formulaValue' = formulaValue |
- requires:
reduction != null && bounds != null && formulaValue != null |
reduction
public Formula reduction()
- Returns this.reduction.
- Returns:
- this.reduction
bounds
public Bounds bounds()
- Return this.bounds.
- Returns:
- this.bounds
formulaValue
public BooleanConstant formulaValue()
- Returns the value to which this.formula is trivially reducible.
- Returns:
- this.formulaValue
skolems
public java.util.Map<Decl,Relation> skolems()
- If the options with which this.formula was translated
specified skolemization, returns a map from existentially
quantified declarations in this.formula to their corrensponding
skolem constants. Otherwise returns null.
- Returns:
- this.skolems
