Method Detail

removeEldestEntry

protected boolean removeEldestEntry(Map.Entry<K,V> eldest)

Returns true if this LruCache has more entries than the maximum specified when it was created.

This method does not modify the underlying Map; it relies on the implementation of LinkedHashMap to do that, but that behavior is documented in the JavaDoc for LinkedHashMap.

Overrides:

removeEldestEntry in class LinkedHashMap<K,V>

Parameters:

eldest - the Entry in question; this implementation doesn't care what It's, since the implementation is only dependent on the size of the cache

Returns:

true if the oldest
