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>
