Method Detail

remove

public Object remove(Object ok)
Description copied from class: AbstractShort2ReferenceMap
Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:
remove in interface Map
Overrides:
remove in class AbstractShort2ReferenceMap

get

public Object get(Object ok)
Description copied from class: AbstractShort2ReferenceMap
Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:
get in interface Map
Overrides:
get in class AbstractShort2ReferenceMap

size

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

containsKey

public boolean containsKey(short k)
Description copied from class: AbstractShort2ReferenceMap
Checks whether the given value is contained in AbstractShort2ReferenceMap.keySet().

Specified by:
containsKey in interface Short2ReferenceMap
Overrides:
containsKey in class AbstractShort2ReferenceMap

containsValue

public boolean containsValue(Object v)
Description copied from class: AbstractShort2ReferenceMap
Checks whether the given value is contained in AbstractShort2ReferenceMap.values().

Specified by:
containsValue in interface Map
Overrides:
containsValue in class AbstractShort2ReferenceMap

defaultReturnValue

public Object defaultReturnValue()
Description copied from interface: Short2ReferenceMap
Gets the default return value.

Specified by:
defaultReturnValue in interface Short2ReferenceMap
Overrides:
defaultReturnValue in class AbstractShort2ReferenceMap

defaultReturnValue

public void defaultReturnValue(Object defRetValue)
Description copied from interface: Short2ReferenceMap
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 Short2ReferenceMap
Overrides:
defaultReturnValue in class AbstractShort2ReferenceMap

put

public Object put(short k,
                  Object v)
Description copied from interface: Short2ReferenceMap
Adds a pair to the map.

Specified by:
put in interface Short2ReferenceMap
Overrides:
put in class AbstractShort2ReferenceMap

putAll

public void putAll(Short2ReferenceMap c)

putAll

public void putAll(Map m)
Description copied from class: AbstractShort2ReferenceMap
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 AbstractShort2ReferenceMap
Parameters:
m - a map.

entrySet

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

keySet

public Set keySet()
Description copied from class: AbstractShort2ReferenceMap
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 AbstractShort2ReferenceMap
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: AbstractShort2ReferenceMap
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 AbstractShort2ReferenceMap
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 AbstractShort2ReferenceMap

toString

public String toString()
Overrides:
toString in class AbstractShort2ReferenceMap

put

public Object put(Object k,
                  Object v)
Description copied from class: AbstractShort2ReferenceMap
Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:
put in interface Map
Overrides:
put in class AbstractShort2ReferenceMap

remove

public Object remove(short k)
Description copied from interface: Short2ReferenceMap
Removes the mapping with the given key.

Specified by:
remove in interface Short2ReferenceMap
Overrides:
remove in class AbstractShort2ReferenceMap

get

public Object get(short k)
Description copied from interface: Short2ReferenceMap
Returns the value to which the given key is mapped.

Specified by:
get in interface Short2ReferenceMap
Parameters:
k - the key.
Returns:
the corresponding value, or the default return value if no value was present for the given key.

Map.get(Object)

containsKey

public boolean containsKey(Object ok)
Specified by:
containsKey in interface Map
Overrides:
containsKey in class AbstractShort2ReferenceMap
