Method Detail

containsValue

public boolean containsValue(short v)

Description copied from interface: Object2ShortMap

Returns true if this map maps one or more keys to the specified value.

Specified by:

containsValue in interface Object2ShortMap<K>

See Also:

Map.containsValue(Object)

containsValue

@Deprecated
public boolean containsValue(java.lang.Object ov)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

containsValue in interface java.util.Map<K,java.lang.Short>

Specified by:

containsValue in interface Object2ShortMap<K>

putAll

public void putAll(java.util.Map<? extends K,? extends java.lang.Short> m)

Specified by:

putAll in interface java.util.Map<K,java.lang.Short>

object2ShortEntrySet

public ObjectSet<Object2ShortMap.Entry<K>> object2ShortEntrySet()

Description copied from interface: Object2ShortMap

Returns a type-specific set view of the mappings contained in this map.

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

object2ShortEntrySet in interface Object2ShortMap<K>

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

Map.entrySet()

entrySet

@Deprecated
public ObjectSet<java.util.Map.Entry<K,java.lang.Short>> entrySet()

Deprecated.

Please use the corresponding type-specific method instead.

Returns a set view of the mappings contained in this map.

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface java.util.Map<K,java.lang.Short>

Specified by:

entrySet in interface Object2ShortMap<K>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public ObjectSet<K> keySet()

Description copied from interface: Object2ShortMap

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface java.util.Map<K,java.lang.Short>

Specified by:

keySet in interface Object2ShortMap<K>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ShortCollection values()

Description copied from interface: Object2ShortMap

Note that this specification strengthens the one given in Map.values().

Specified by:

values in interface java.util.Map<K,java.lang.Short>

Specified by:

values in interface Object2ShortMap<K>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface java.util.Map<K,java.lang.Short>

hashCode

public int hashCode()

Specified by:

hashCode in interface java.util.Map<K,java.lang.Short>

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.util.Map<K,java.lang.Short>

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
