Method Summary

Modifier and Type	Method and Description
boolean	equals(Object o) checks whether the other object is a formula of the same structure.
int	hashCode() returns a valid hashCode satisfying the constraints given by Formula.equals(java.lang.Object).

Method Detail

toString

public final String toString()

Description copied from interface: Formula

returns an arbitrary representation of the formula, might be human- or machine-readable.

We do not guarantee that the returned String is in any way related to the formula. The solver might apply escaping or even un-escaping. A user should not use the returned String for further processing. For analyzing formulas, we recommend to use a FormulaVisitor.

Specified by:

toString in interface Formula

Overrides:

toString in class Object

equals

public final boolean equals(Object o)

Description copied from interface: Formula

checks whether the other object is a formula of the same structure. Does not apply an expensive SAT-check to check equisatisfiability.

Two formulas that are structured in the same way, are determined as "equal". Due to transformations and simplifications, two equisatisfiable formulas with different structure might not be determined as "equal".

hashCode

public final int hashCode()

Description copied from interface: Formula

returns a valid hashCode satisfying the constraints given by Formula.equals(java.lang.Object).
