- All Implemented Interfaces:

,ToDOM
,ToJson
,java.io.Serializable
,java.lang.Cloneable
,java.lang.Comparable<Term>
public class RelExpr extends BinaryStructure implements LogicalFormula
Represents a relational expression like 10 > 20.
When the operator is =.., the first argument is a literal and the
second as list, e.g.:
Literal =.. [functor, list of terms, list of annots]
Examples:
- X =.. [~p, [t1, t2], [a1,a2]]
X is ~p(t1,t2)[a1,a2] - ~p(t1,t2)[a1,a2] =.. X
X is [~p, [t1, t2], [a1,a2]]
