public class Maps
An aggregation of abstract and concrete implementations of the Maps.AbstractHashMap
interface which address various usage scenarios.
Most of the concrete map classes provided here extend, directly or indirectly, the abstract class Maps.AbstractHashMap
, which provides a more extensible replacement for HashMap
. These concrete classes are the following:
Maps.StrongHashMap
A standard hash map: a direct but more extensible replacement for HashMap
.Maps.SoftHashMap
A hash map with softly-referenced values.Maps.WeakHashMap
A hash map with weakly-referenced values.Maps.StrongLinkedHashMap
A standard linked hash map: a direct but more extensible replacement for LinkedHashMap
.Maps.SoftLinkedHashMap
A linked hash map with softly-referenced values.Maps.WeakLinkedHashMap
A linked hash map with weakly-referenced values.Maps.CacheMap
A linked hash map with pluggable caching strategies.Maps.ManagedCacheMap
A cache map that is remotely monitorable as a managed bean.The following concrete Maps.CacheStrategy
classes are provided:
Maps.UnboundedCacheStrategy
A strategy for an unbounded cache (effectively, a plain linked hash map).Maps.BoundedLruCacheStrategy
A strategy for a bounded LRU cache.Maps.TimedLruCacheStrategy
A strategy for a timed, bounded LRU cache.Nested Class Summary | |

Maps.AbstractHashMap<K,V,E extends Maps.BaseEntry<K,V>> An abstract, but nearly complete, implementation of the Map interface that is functionally equivalent to HashMap but that allows subclasses to do any or all of the following: control the concrete class of Map.Entry instances used so long as they extend Maps.BaseEntry (see Maps.AbstractHashMap.createEntry(int, K, V, E) ); override the calculation of hashCode and equals for all keys (see Maps.AbstractHashMap.keyHashCode(java.lang.Object) and Maps.AbstractHashMap.keyEquals(java.lang.Object, java.lang.Object) ); override the calculation of hashCode and equals for all values (see Maps.AbstractHashMap.valueHashCode(java.lang.Object) and Maps.AbstractHashMap.valueEquals(java.lang.Object, java.lang.Object) ); track when the map is constructed, initialized, and changed (see Maps.AbstractHashMap.mapConstructed() , Maps.AbstractHashMap.mapInitialized() , and Maps.AbstractHashMap.mapChanged() ). |
