This class implements an LRU dictionary cache. The two operations on it are
|
|
get() and set(), both of which promote the key being referenced to the ``top''
|
|
of the cache, so it will stay alive longest. When the cache is full and a
|
|
new item needs to be added, the oldest one is thrown away. You should be able
|
|
to regenerate the data at any time, if get() returns undef. This class is
|
|
useful for caching information from a slower data source while also keeping
|
|
a bound on memory usage.
