Direct Known Subclasses:

public class Linear1

extends java.lang.Object

Fundamental class for constructing linear recursive objects.

Field Summary

protected java.lang.Object	data Field (possibly null) referencing the object associated to this Linear1 object.
protected Linear1	link Field (possibly null) referencing the Linear1 object that follows this one in the recursive structure.

Constructor Summary

Linear1()
Constructs a "null" Linear1 object.

Linear1(java.lang.Object data)
Constructs an non-empty Linear1 object with no recursive reference (a null reference).

Linear1(java.lang.Object data, Linear1 link)
Constructs a non empty Linear1 object with a recursive reference to a next (possibly null) object.

Method Summary

Linear1	factory() Returns a null Linear1() object
java.lang.Object	getData() Returns reference to the object referenced by the data field.
Linear1	getLink() Returns reference to the next Linear1 recursive object.
void	setData(java.lang.Object newData) Replace the current data field reference with a reference to newData.
void	setLink(Linear1 newLink) Replace the current contents of the link field with a reference to the newLink Linear1 object.
java.lang.String	toString() Returns a string composed of a tab delimited sequence of the data.toString()s of the objects in the recursive Linear1 structure.

Linear1

public Linear1(java.lang.Object data,
               Linear1 link)

Constructs a non empty Linear1 object with a recursive reference to a next (possibly null) object.

Parameters:

data - Reference to the object that corresponds to this Linear1 object.

Method Detail

getData

public java.lang.Object getData()

Returns reference to the object referenced by the data field.

Returns:

Object Reference to the current associated object.

setData

Replace the current data field reference with a reference to newData.

Parameters:

newData - New object to be associated with this Linear1 object.

getLink

public Linear1 getLink()

Returns reference to the next Linear1 recursive object. WARNING: if improperly used it could create an alias to the object references by link.

Returns:

Linear1 Reference (possibly null) to the next recursive Linear1 object.

setLink

Returns:

String Returns a tab delimited string of the objects in the recursive Linear1 structure.

factory

public Linear1 factory()

Returns a null Linear1() object

Returns:

A null Linear1() object
