public interface Element<C extends Element<C>>
extends java.lang.Cloneable, java.lang.Comparable<C>, java.io.Serializable

Element interface. Basic functionality of elements, e.g. compareTo, equals, clone.

Author:

Heinz Kredel

Type parameter:

C element type.

Method Summary

C	clone() Clone this Element.
int	compareTo(C b) Compare this to b.
boolean	equals(java.lang.Object b) Test if this is equal to b.
int	hashCode() Hashcode of this Element.

Method Detail

clone

C clone()

Clone this Element.

Returns:

Creates and returns a copy of this Elemnt.

equals

boolean equals(java.lang.Object b)

Test if this is equal to b.

Overrides:

equals in class java.lang.Object

Parameters:

b -

Returns:

true if this is equal to b, else false.

hashCode

int hashCode()

Hashcode of this Element.

Overrides:

hashCode in class java.lang.Object

Returns:

the hashCode.

compareTo

int compareTo(C b)

Compare this to b. I.e. this < b iff this.compareTo(b) < 0. Note: may not be meaningful if structure has no order.

Specified by:

compareTo in interface java.lang.Comparable<C extends Element<C>>

Parameters:

b -

Returns:

0 if this is equal to b, -1 if this is less then b, else +1.
