Method Detail

get

public V get(java.lang.Object key)
Specified by:
get in interface java.util.Map<K,V>
Overrides:
get in class java.util.AbstractMap<K,V>

put

public V put(K key,
             V value)
Specified by:
put in interface java.util.Map<K,V>
Overrides:
put in class java.util.AbstractMap<K,V>

remove

public V remove(java.lang.Object key)
Specified by:
remove in interface java.util.Map<K,V>
Overrides:
remove in class java.util.AbstractMap<K,V>

clear

public void clear()
Specified by:
clear in interface java.util.Map<K,V>
Overrides:
clear in class java.util.AbstractMap<K,V>

size

public int size()
Specified by:
size in interface java.util.Map<K,V>
Overrides:
size in class java.util.AbstractMap<K,V>

entrySet

public java.util.Set<java.util.Map.Entry<K,V>> entrySet()
Returns a copy of the key/values in the map at the point of calling. However, setValue still sets the value in the actual SoftHashMap.

Specified by:
entrySet in interface java.util.Map<K,V>
Specified by:
entrySet in class java.util.AbstractMap<K,V>
