Constructor Detail

FastCopyHashMap

public FastCopyHashMap(int initialCapacity,
                       float loadFactor)

FastCopyHashMap

public FastCopyHashMap(Map<? extends K,? extends V> map)

FastCopyHashMap

public FastCopyHashMap(int initialCapacity)

FastCopyHashMap

public FastCopyHashMap()
Method Detail

size

public int size()
Specified by:
size in interface Map<K,V>

isEmpty

public boolean isEmpty()
Specified by:
isEmpty in interface Map<K,V>

get

public V get(Object key)
Specified by:
get in interface Map<K,V>

containsKey

public boolean containsKey(Object key)
Specified by:
containsKey in interface Map<K,V>

toString

public String toString()
Returns a string representation of this map. The string representation consists of a list of key-value mappings in the order returned by the map's entrySet view's iterator, enclosed in braces ("{}"). Adjacent mappings are separated by the characters ", " (comma and space). Each key-value mapping is rendered as the key followed by an equals sign ("=") followed by the associated value. Keys and values are converted to strings as by String.valueOf(Object).

Overrides:
toString in class Object
Returns:
a string representation of this map

containsValue

public boolean containsValue(Object value)
Specified by:
containsValue in interface Map<K,V>

put

public V put(K key,
             V value)
Specified by:
put in interface Map<K,V>

putAll

public void putAll(Map<? extends K,? extends V> map)
Specified by:
putAll in interface Map<K,V>

remove

public V remove(Object key)
Specified by:
remove in interface Map<K,V>

clear

public void clear()
Specified by:
clear in interface Map<K,V>

clone

public FastCopyHashMap<K,V> clone()
Overrides:
clone in class Object

printDebugStats

public void printDebugStats()

values

public Collection<V> values()
Specified by:
values in interface Map<K,V>

keySet

public Set<K> keySet()
Specified by:
keySet in interface Map<K,V>

entrySet

public Set<Map.Entry<K,V>> entrySet()
Specified by:
entrySet in interface Map<K,V>
