Class HardRefCache
java.lang.Object
org.jpox.cache.HardRefCache
- All Implemented Interfaces:
- Level1Cache, java.util.Map
- public class HardRefCache
- extends java.lang.Object
- implements Level1Cache
Implementation of a Level 1 cache keeping hard (strong) references
to the objects. This means that objects are not garbage collected,
and have to be removed directly by calls to remove(). This differs
from the WeakRefCache/SoftRefCache which do not guarantee to retain
objects.
