TupleBvr Class

public class TupleBvr extends Behavior
     //Constructor
     public TupleBvr(Behavior[] tuple);

     //Methods
     public Behavior nth(int i);
     public int length();

     public static TupleBvr newUninitBvr(TupleBvr tuple);
}

A TupleBvr object is similar to an array. It can, however, accept heterogeneous types. The two methods included in this class are convenience utilities. Any number of members can be included in a TupleBvr object.

• TupleBvr Constructor
• TupleBvr Methods
• Relevant Methods from the Statics Class

TupleBvr Constructor

TupleBvr Class

Constructs the TupleBvr object.

public TupleBvr(
  Behavior behaviors[]
  );

Parameters

behaviors

The behaviors to be included in the TupleBvr.

---

TupleBvr Methods

length

nth

newUninit

---

length

TupleBvr Class

Determines the length of a tuple behavior.

public int length( );

Return Values

Returns an integer. For more information about integers, consult a Java reference.

---

nth

TupleBvr Class

Selects a Behavior object based on the value of i.

public Behavior nth(
  int i
  );

Parameters

i

The index into the TupleBvr object. Note that this is not a time-varying index.

---

newUninit

TupleBvr Class

Allows you to refer to an Transform3Bvr behavior before that behavior has been defined. With this method you can create the behavior and use it in the definition of other behaviors, but not actually define its contents until some later point. (This is accomplished with the init method, which is available on all behaviors.) The system generates a run-time error if you initialize a non-uninitialized behavior, initialize an uninitialized behavior that has already been initialized, or run an initialized behavior that has not yet been initialized.

public static TupleBvr newUninitBvr(
  TupleBvr tuple
  );

Parameters

tuple

Used to establish the type the tuple holds.

Return Values

Returns the TupleBvr object.

Relevant Methods from the Statics Class

The following methods are defined in the Statics and are most relevant to objects of type TupleBvr.

public static TupleBvr pairBvr(Behavior first, Behavior second);

public static TupleBvr tripleBvr(Behavior first, Behavior second, Behavior third);
