alice.logictuple
Class TupleArgument  

java.lang.Object
  alice.logictuple.TupleArgument

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

Value, Var

---

public class TupleArgument

extends java.lang.Object

implements java.io.Serializable

Defines an argument of logic tuple. The argument can be a value (Value class) or a variable (Var class). The argument can be constructed using Value or Var - which are used only as constructor classes; instead, the services about argument management are provided by this class

Version:

1.0

Field Summary
protected  alice.tuprolog.Term	value           the internal representation of the argument is a (tu)Prolog term

 

Constructor Summary

TupleArgument()

TupleArgument(java.lang.Object t)           Constructs an argument using a generic object

TupleArgument(alice.tuprolog.Term t)           Contructs a tuple argument copying a Prolog term

 

Method Summary
TupleArgument	getArg(int index)           gets the i-arg Arg of a structured argument
