public class TObjectShortMapDecorator<K> extends java.util.AbstractMap<K,java.lang.Short> implements java.util.Map<K,java.lang.Short>, java.io.Externalizable, java.lang.Cloneable
Wrapper class to make a TObjectShortMap conform to the java.util.Map API. This class simply decorates an underlying TObjectShortMap and translates the Object-based APIs into their Trove primitive analogs. Note that wrapping and unwrapping primitive values is extremely inefficient. If possible, users of this class should override the appropriate methods in this class and use a table of canonical values. Created: Mon Sep 23 22:07:40 PDT 2002- See Also:

TObjectShortMapDecorator
public TObjectShortMapDecorator()
FOR EXTERNALIZATION ONLY!!
-
TObjectShortMapDecorator
public TObjectShortMapDecorator(TObjectShortMap<K> map)
Creates a wrapper that decorates the specified primitive map.- Parameters:
map
- the TObjectShortMap to wrap.
-
-
Method Detail
-
getMap
public TObjectShortMap<K> getMap()
Returns a reference to the map wrapped by this decorator.- Returns:
- the wrapped TObjectShortMap instance.
-
put
public java.lang.Short put(K key, java.lang.Short value)
Inserts a key/value pair into the map.
-
get
public java.lang.Short get(java.lang.Object key)
Retrieves the value for key
-
clear
public void clear()
Empties the map.
-
remove
public java.lang.Short remove(java.lang.Object key)
Deletes a key/value pair from the map.
-
entrySet
public java.util.Set<java.util.Map.Entry<K,java.lang.Short>> entrySet()
Returns a Set view on the entries of the map.
-
containsValue
public boolean containsValue(java.lang.Object val)
Checks for the presence of val in the values of the map.
-
containsKey
public boolean containsKey(java.lang.Object key)
Checks for the present of key in the keys of the map.
-
size
public int size()
Returns the number of entries in the map.
-
isEmpty
public boolean isEmpty()
Indicates whether map has any entries.
-
putAll
public void putAll(java.util.Map<? extends K,? extends java.lang.Short> map)
Copies the key/value mappings in map into this map. Note that this will be a deep copy, as storage is by primitive value.
-
wrapValue
protected java.lang.Short wrapValue(short k)
Wraps a value- Parameters:
k
- value in the underlying map- Returns:
- an Object representation of the value
-
unwrapValue
protected short unwrapValue(java.lang.Object value)
Unwraps a value- Parameters:
value
- wrapped value- Returns:
- an unwrapped representation of the value
-
