Class SignedInteger

java.lang.Object
  org.at4j.support.lang.SignedInteger

All Implemented Interfaces:

Comparable<SignedInteger>

public class SignedInteger
extends Object
implements Comparable<SignedInteger>

This class represents a signed integer value (i.e. a plain int value). If the Integer class had not been declared final, this class would probably have extended it.

Signed integer objects are created by calling any of the static creation methods on this class.

Instances of this class are immutable.

Since:

1.1.1
