Constructor Detail

KeyedObject

public KeyedObject(K key,
                   Object object)

Creates a new (key, object) pair.

Parameters:

key - the key.

object - the object (null permitted).

Method Detail

getKey

public K getKey()

Returns the key.

Returns:

The key.

getObject

public Object getObject()

Returns the object.

Returns:

The object (possibly null).

setObject

public void setObject(Object object)

Sets the object.

Parameters:

object - the object (null permitted).

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of this object. It is assumed that the key is an immutable object, so it is not deep-cloned. The object is deep-cloned if it implements PublicCloneable, otherwise a shallow clone is made.

Specified by:

clone in interface PublicCloneable

Overrides:

clone in class Object

Returns:

A clone.

Throws:

CloneNotSupportedException - if there is a problem cloning.

equals

public boolean equals(Object obj)

Tests if this object is equal to another.

Overrides:

equals in class Object

Parameters:

obj - the other object.

Returns:

A boolean.

hashCode

public int hashCode()

Overrides:
