getKey

public java.lang.Object getKey()

Description copied from interface: LRUShell

Devuelve la clave a la que está asociado este objeto. Generalmente es un dato redundante, porque se tuvo que conocer para poder buscar este objeto en una cache.

Specified by:

getKey in interface LRUShell

---

getValue

public ExpiringObject getValue()

Description copied from interface: LRUShell

Devuelve el valor que contiene este objeto y que se supone que es el valor para la clave LRUShell.getKey() 55 . Cuando este objeto no tiene valor asociado, la primera llamada devuelve null y las siguiente se quedan bloqueadas hasta que la primera llama a LRUShell.put(ExpiringObject) 55 o LRUShell.release() 55 .

Specified by:

getValue in interface LRUShell

---

put

public void put(ExpiringObject value)
         throws java.lang.IllegalStateException

Description copied from interface: LRUShell

Pone el valor a value, cuando el objeto está indefinido. Pero produce una excepción java.lang.IllegalStateException si ya había recibido un valor.

Specified by:

put in interface LRUShell

---

release

public void release()

Description copied from interface: LRUShell

Indica a la caché de la que lo hemos sacado que ya no lo estamos usando y que, por nosotros, puede empezar a pensar en su muerte.

Specified by:

release in interface LRUShell

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
