  • Constructor Details

    • DualSetSignature

      public DualSetSignature()
      Creates a new empty signature.

    • DualSetSignature

      public DualSetSignature(Set<T> args1, Set<S> args2)
      Creates a new signature with the given sets of formulas.
      Parameters:
      args1 - a set of formulas
      args2 - a set of formulas

  • Method Details

    • isSubSignature

      public boolean isSubSignature(Signature other)
      Description copied from interface: Signature
      Checks whether this signature is a sub-signature of the given signature, i.e. whether each logical expression expressible with this signature is also expressible with the given signature.
      Specified by:
      isSubSignature in interface Signature
      Parameters:
      other - a signature.
      Returns:
      "true" iff this signature is a sub-signature of the given one.

    • isOverlappingSignature

      public boolean isOverlappingSignature(Signature other)
      Description copied from interface: Signature
      Checks whether this signature has common elements with the given signature, i.e. whether there are logical expressions expressible with this signature that are also expressible with the given signature.
      Specified by:
      isOverlappingSignature in interface Signature
      Parameters:
      other - a signature.
      Returns:
      "true" iff this signature is overlapping with the given one.

    • addSignature

      public void addSignature(Signature other)
      Description copied from interface: Signature
      Adds the elements of the given signature to this signature.
      Specified by:
      addSignature in interface Signature
      Parameters:
      other - a signature.

    • hashCode

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

    • equals

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

    • addAll

      public void addAll(Collection<?> c)
      Description copied from interface: Signature
      Adds all elements of this collection to this signature.
      Specified by:
      addAll in interface Signature
      Parameters:
      c - a collection

    • add

      public void add(Object... objects) throws IllegalArgumentException

      Adds the given formulas to the signature.
      Specified by:
      add in interface Signature
      Parameters:

      Throws:
      IllegalArgumentException

    • isEmpty

      public boolean isEmpty()
      Description copied from interface: Signature
      Returns true if this signature is empty.
      Specified by:
      isEmpty in interface Signature

    • removeAll

      public void removeAll(Collection<?> c)
      Description copied from interface: Signature
      Removes all of this signature elements that are also contained in the specified collection (optional operation). After this call returns, this signature will contain no elements in common with the specified collection.
