void |
addToSignature(PanSignature signature)
This method adds this Term to the passed PanSignature IF it is not already in the signature. |
java.lang.String |
clashes(PanSignature signature)
Returns a String of error message if this Term clashes with the passed PanSignature. A Term clashes with a PanSignature if it clashes with any of its Predicates,Constants,Functions or Variables. If this Term does not clash with the Signature, it is added to the signature and an empty String is returned. |
