Class Variable

  • All Implemented Interfaces:
    LogicStructure, Term<java.lang.String>
    public class Variable
extends StringTerm
    A Variable is a placeholder for Constants in a generic formula of a logic language. For example, wife_of(X,Y) represents all wifes X and their specific husbands Y using the two Variables X,Y. It is implemented as a specialized StringTerm which only allows names which have an upper-case character as first letter.
