Method Detail

remove

public Object remove(Object ok)
Specified by:
remove in interface Map
Overrides:
remove in class AbstractReference2ReferenceMap

get

public Object get(Object ok)
Specified by:
get in interface Map

size

public int size()
Specified by:
size in interface Map

containsKey

public boolean containsKey(Object k)
Description copied from class: AbstractReference2ReferenceMap
Checks whether the given value is contained in AbstractReference2ReferenceMap.keySet().

Specified by:
containsKey in interface Map
Overrides:
containsKey in class AbstractReference2ReferenceMap

containsValue

public boolean containsValue(Object v)
Description copied from class: AbstractReference2ReferenceMap
Checks whether the given value is contained in AbstractReference2ReferenceMap.values().

Specified by:
containsValue in interface Map
Overrides:
containsValue in class AbstractReference2ReferenceMap

defaultReturnValue

public Object defaultReturnValue()
Description copied from interface: Reference2ReferenceMap
Gets the default return value.

Specified by:
defaultReturnValue in interface Reference2ReferenceMap
Overrides:
defaultReturnValue in class AbstractReference2ReferenceMap

defaultReturnValue

public void defaultReturnValue(Object defRetValue)
Description copied from interface: Reference2ReferenceMap
Sets the default return value. This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.

Specified by:
defaultReturnValue in interface Reference2ReferenceMap
Overrides:
defaultReturnValue in class AbstractReference2ReferenceMap

put

public Object put(Object k,
                  Object v)
Specified by:
put in interface Map
Overrides:
put in class AbstractReference2ReferenceMap

putAll

public void putAll(Reference2ReferenceMap c)

putAll

public void putAll(Map m)
Description copied from class: AbstractReference2ReferenceMap
Puts all pairs in the given map. If the map implements the interface of this map, it uses the faster iterators.

Specified by:
putAll in interface Map
Overrides:
putAll in class AbstractReference2ReferenceMap
Parameters:
m - a map.

entrySet

public Set entrySet()
Specified by:
entrySet in interface Map

keySet

public Set keySet()
Description copied from class: AbstractReference2ReferenceMap
Returns a type-specific-set view of the keys of this map.

The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:
keySet in interface Map
Overrides:
keySet in class AbstractReference2ReferenceMap
Returns:
a set view of the keys of this map; it may be safely cast to a type-specific interface.

values

public Collection values()
Description copied from class: AbstractReference2ReferenceMap
Returns a type-specific-set view of the values of this map.

The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:
values in interface Map
Overrides:
values in class AbstractReference2ReferenceMap
Returns:
a set view of the values of this map; it may be safely cast to a type-specific interface.

clear

public void clear()
Specified by:
clear in interface Map
Overrides:
clear in class AbstractReference2ReferenceMap

toString

public String toString()
Overrides:
toString in class AbstractReference2ReferenceMap
