Constructor:

Constructor:
public UnlimitedCache() { super(); maxEntries = UNLIMITED; } Creates an unlimited cache by calling the super class's constructor with an `UNLIMITED` maximum number of entries.

 public UnlimitedCache() {
                          
        super();
        maxEntries = UNLIMITED;
}

Creates an unlimited cache by calling the super class's constructor with an UNLIMITED maximum number of entries.

Method from com.opensymphony.oscache.base.algorithm.UnlimitedCache Summary:
itemPut, itemRemoved, itemRetrieved, removeItem, setMaxEntries

Methods from java.lang.Object:
equals, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Method from com.opensymphony.oscache.base.algorithm.UnlimitedCache Detail:
protected void itemPut(Object key) { } Implements `itemPut` with an empty implementation. The unlimited cache doesn't care that an item was put in the cache.
protected void itemRemoved(Object key) { } An empty implementation. The unlimited cache doesn't care that an item was removed.
protected void itemRetrieved(Object key) { } Implements `itemRetrieved` with an empty implementation. The unlimited cache doesn't care that an item was retrieved.
protected Object removeItem() { return null; } This method just returns `null` since items should never end up being removed from an unlimited cache!
public void setMaxEntries(int maxEntries) { log.warn("Cache max entries can't be set in " + this.getClass().getName() + ", ignoring value " + maxEntries + "."); } Overrides the `setMaxEntries` with an empty implementation. This property cannot be modified and is ignored for an `UnlimitedCache`.
