Method Detail

containsKey

public boolean containsKey(short k)

Description copied from class: AbstractShort2IntMap

Checks whether the given value is contained in AbstractShort2IntMap.keySet().

Specified by:

containsKey in interface Short2IntMap

Overrides:

containsKey in class AbstractShort2IntMap

containsValue

public boolean containsValue(int v)

Description copied from class: AbstractShort2IntMap

Checks whether the given value is contained in AbstractShort2IntMap.values().

Specified by:

containsValue in interface Short2IntMap

Overrides:

containsValue in class AbstractShort2IntMap

putAll

public void putAll(Map m)

Description copied from class: AbstractShort2IntMap

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 AbstractShort2IntMap

Parameters:

m - a map.

entrySet

public Set entrySet()

Specified by:

entrySet in interface Map

keySet

public Set keySet()

Description copied from class: AbstractShort2IntMap

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 AbstractShort2IntMap

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: AbstractShort2IntMap

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 AbstractShort2IntMap

Returns:

a set view of the values of this map; it may be safely cast to a type-specific interface.

get

public int get(short k)

Description copied from interface: Short2IntMap

Returns the value to which the given key is mapped.

Specified by:

get in interface Short2IntMap

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)

size

public int size()

Specified by:

size in interface Map

clone

public Object clone()
