Class Tuple<T>

  • All Implemented Interfaces:
    com.google.gwt.user.client.rpc.IsSerializable, Serializable, Iterable<T>
    public class Tuple<T>
extends Object
implements Iterable<T>, Serializable, com.google.gwt.user.client.rpc.IsSerializable
    General purpose tuple representation. A tuple is a sequence (or ordered list) of finite length. 
     Example:

 1) Creation
 // single typed tuple
 Tuple<Long> nt = new Tuple<Long>(42L);

 // multi typed tuple
 Tuple<Object> ot = new Tuple<Object>("Lars Tackmann",
                "Age", 26);

 2) Usage
 // get single element
 Integer val = (Integer) ot.get(2);
 // iterate tuple
 for (Object o : ot)
   System.out.printf("'%s' ", o.toString());
 // print all elems
 System.out.printf("Object tuple: %s\n", ot.toString());


 3) Operations
 // The elements of two tuples a and b can be joined with
 // union operation that returns a new tuple.
 Tuple c = a.union (b);

        Parameters:
        obj - the Tuple element to compare
        Returns:
        true if the number of contained elements is the same and all the elements are equals.
