Method Details

containsValue

public boolean containsValue(java.lang.Object v)

Specified by:

containsValue in interface java.util.Map<java.lang.Byte,V>

putAll

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

Specified by:

putAll in interface java.util.Map<java.lang.Byte,V>

byte2ReferenceEntrySet

public ObjectSet<Byte2ReferenceMap.Entry<V>> byte2ReferenceEntrySet()

Description copied from interface: Byte2ReferenceMap

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:

byte2ReferenceEntrySet in interface Byte2ReferenceMap<V>

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<java.lang.Byte,V>> entrySet()

Deprecated.

Please use the corresponding type-specific method instead.

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

Specified by:

entrySet in interface Byte2ReferenceMap<V>

Specified by:

entrySet in interface java.util.Map<java.lang.Byte,V>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public ByteSet keySet()

Description copied from interface: Byte2ReferenceMap

Specified by:

keySet in interface Byte2ReferenceMap<V>

Specified by:

keySet in interface java.util.Map<java.lang.Byte,V>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ReferenceCollection<V> values()

Description copied from interface: Byte2ReferenceMap

Specified by:

values in interface Byte2ReferenceMap<V>

Specified by:

values in interface java.util.Map<java.lang.Byte,V>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

isEmpty

Specified by:

isEmpty in interface java.util.Map<java.lang.Byte,V>

hashCode

public int hashCode()

Overrides:

toString in class java.lang.Object
