      Description copied from interface: Formula
      Returns the signature of the language of this formula.
      Returns:
      the signature of the language of this formula.

    • getPremise

      public Collection<? extends T> getPremise()
      Description copied from interface: Rule
      Returns the premise of this rule.
      Returns:
      the premise of this rule.

      public T getConclusion()
      Description copied from interface: Rule
      Returns the conclusion of this rule.
      Returns:
      the conclusion of this rule.

    • isAssumption

      public boolean isAssumption()
      Description copied from class: AbaRule
      Return whether this rule is an assumption
      Specified by:
      isAssumption in class AbaRule<T extends Formula>
      Returns:
      whether this rule is an assumption

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • hashCode

      public int hashCode()
      Specified by:
      hashCode in interface SimpleLogicalFormula
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object obj)
      Specified by:
      equals in interface SimpleLogicalFormula
      Overrides:
      equals in class Object

    • getPredicates

      public Set<? extends Predicate> getPredicates()
      Description copied from interface: SimpleLogicalFormula
      Processes the set of all predicates which appear in this formula
      Returns:
