  • 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.
