Constructor Detail

Maps.CacheMap

public Maps.CacheMap()

Constructs an unbounded, hard-referenced value cache map. The initial capacity and load factor are set to default values; the mapping type is noncanonical (as is typical for an unbounded cache).

Maps.CacheMap

public Maps.CacheMap(Maps.AbstractCacheMap.ReferenceType valueReferenceType)

Constructs an unbounded cache map of specified value reference type. The initial capacity and load factor are set to default values; the mapping type is noncanonical (as is typical for an unbounded cache).

Maps.CacheMap

public Maps.CacheMap(int bound)

Constructs a bounded LRU (least recently used), hard-referenced cache map. The initial capacity and load factor are set to default values; the mapping type is canonical.

Parameters:

bound - The maximum number of values to cache.

Maps.CacheMap

public Maps.CacheMap(int bound,
                     Maps.AbstractCacheMap.ReferenceType valueReferenceType)

Constructs a bounded LRU (least recently used), hard-referenced cache map. The initial capacity and load factor are set to default values; the mapping type is canonical.

Parameters:

bound - The maximum number of values to cache.

Maps.CacheMap

public Maps.CacheMap(int bound,
                     Maps.AbstractCacheMap.MappingType mappingType)

Constructs a bounded LRU (least recently used), hard-referenced, canonically-mapped, cache map. The initial capacity and load factor are set to default values.

Parameters:

bound - The maximum number of values to cache.

Maps.CacheMap

public Maps.CacheMap(Maps.CacheStrategy<K,V,Maps.AbstractLinkedEntry<K,V>> strategy)

Constructs a cache map with specified Maps.CacheStrategy..
