CopyOnWriteMaps()

Method Summary

static <K,V> CopyOnWriteMap<K,V>	newHashMap() Creates a new CopyOnWriteMap with an underlying HashMap.
static <K,V> CopyOnWriteMap<K,V>	newHashMap(java.util.Map<? extends K,? extends V> map) Creates a new CopyOnWriteMap with an underlying HashMap using the supplied map as the initial values.
static <K,V> CopyOnWriteMap<K,V>	newLinkedMap() Creates a new CopyOnWriteMap with an underlying LinkedHashMap.
static <K,V> CopyOnWriteMap<K,V>	newLinkedMap(java.util.Map<? extends K,? extends V> map) Creates a new CopyOnWriteMap with an underlying LinkedHashMap using the supplied map as the initial values.
static <K,V> CopyOnWriteSortedMap<K,V>	newTreeMap() Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap and the sort uses the key's natural order.
static <K,V> CopyOnWriteSortedMap<K,V>	newTreeMap(java.util.Comparator<? super K> comparator) Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap.
static <K,V> CopyOnWriteSortedMap<K,V>	newTreeMap(java.util.Map<? extends K,? extends V> map) Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap, the sort uses the key's natural order and the initial values are supplied.
static <K,V> CopyOnWriteSortedMap<K,V>	newTreeMap(java.util.Map<? extends K,? extends V> map, java.util.Comparator<? super K> comparator) Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap, the sort uses the key's natural order and the initial values are supplied.

CopyOnWriteMaps

public CopyOnWriteMaps()

Method Detail

newHashMap

public static <K,V> CopyOnWriteMap<K,V> newHashMap()

Creates a new CopyOnWriteMap with an underlying HashMap.

newHashMap

public static <K,V> CopyOnWriteMap<K,V> newHashMap(java.util.Map<? extends K,? extends V> map)

Creates a new CopyOnWriteMap with an underlying HashMap using the supplied map as the initial values.

newLinkedMap

public static <K,V> CopyOnWriteMap<K,V> newLinkedMap()

Creates a new CopyOnWriteMap with an underlying LinkedHashMap. Iterators for this map will be return elements in insertion order.

newLinkedMap

public static <K,V> CopyOnWriteMap<K,V> newLinkedMap(java.util.Map<? extends K,? extends V> map)

Creates a new CopyOnWriteMap with an underlying LinkedHashMap using the supplied map as the initial values. Iterators for this map will be return elements in insertion order.

newTreeMap

public static <K,V> CopyOnWriteSortedMap<K,V> newTreeMap()

Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap and the sort uses the key's natural order.

newTreeMap

public static <K,V> CopyOnWriteSortedMap<K,V> newTreeMap(java.util.Map<? extends K,? extends V> map)

Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap, the sort uses the key's natural order and the initial values are supplied.

Parameters:

the - map to use as the initial values.

newTreeMap

public static <K,V> CopyOnWriteSortedMap<K,V> newTreeMap(java.util.Comparator<? super K> comparator)

Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap.

Parameters:

the - Comparator to use for ordering the keys.

newTreeMap

public static <K,V> CopyOnWriteSortedMap<K,V> newTreeMap(java.util.Map<? extends K,? extends V> map,
                                                         java.util.Comparator<? super K> comparator)

Create a new CopyOnWriteSortedMap where the underlying map instances are TreeMap, the sort uses the key's natural order and the initial values are supplied.

Parameters:

map - to use as the initial values.

comparator - for ordering.
