Method Details

close

protected boolean close(LRUCache.LRUCacheEntry<K,JavaElementInfo> entry)

Returns true if the element is successfully closed and removed from the cache, otherwise false.

NOTE: this triggers an external removal of this element by closing the element.

Specified by:

close in class OverflowingLRUCache<K extends IJavaElement & IOpenable,JavaElementInfo>

ensureSpaceLimit

protected void ensureSpaceLimit(JavaElementInfo info,
 IJavaElement parent)

newInstance

protected ElementCache<K> newInstance(int size,
 int newOverflow)

Description copied from class: OverflowingLRUCache

Returns a new instance of the reciever.

Specified by:

newInstance in class OverflowingLRUCache<K extends IJavaElement & IOpenable,JavaElementInfo>

resetSpaceLimit

protected void resetSpaceLimit(int defaultLimit,
 IJavaElement parent)
