net.sf.duro.UpdatableInteger

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<UpdatableInteger>

public class UpdatableInteger
extends java.lang.Number
implements java.lang.Comparable<UpdatableInteger>

Instances of this class wrap a value of the primitive type int in an object. Unlike with java.lang.Integer, the value can be updated.

hashCode

public int hashCode()

Returns a hash code for this object.

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Compares this object to the specified object. The result is true if and only if the argument is not null and is an UpdatableInteger object that contains the same value as this object.

equals in class java.lang.Object

Parameters:

obj - the object to compare with.

Returns:

true if the objects are the same; false otherwise.

toString

public java.lang.String toString()

Returns a String object representing this Integer's value. The value is converted to signed decimal representation and returned as a string.

Overrides:

toString in class java.lang.Object

Returns:

a string representation of the value of this object in base 10.

setValue

public void setValue(int value)

Sets the value wrapped by this object.

Parameters:

value - the new value wrapped by this object.
