Method Details

containsValue

public boolean containsValue(byte v)

Description copied from interface: Int2ByteMap

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

Specified by:

containsValue in interface Int2ByteMap

See Also:

• Map.containsValue(Object)

containsValue

@Deprecated
public boolean containsValue(Object ov)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

containsValue in interface Int2ByteMap

Specified by:

containsValue in interface Map<Integer,Byte>

putAll

public void putAll(Map<? extends Integer,? extends Byte> m)

Specified by:

putAll in interface Map<Integer,Byte>

int2ByteEntrySet

public ObjectSet<Int2ByteMap.Entry> int2ByteEntrySet()

Description copied from interface: Int2ByteMap

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:

int2ByteEntrySet in interface Int2ByteMap

Returns:

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

See Also:

• Map.entrySet()

entrySet

@Deprecated
public ObjectSet<Map.Entry<Integer,Byte>> 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 Int2ByteMap

Specified by:

entrySet in interface Map<Integer,Byte>

Returns:

a set view of the mappings contained in this map.

See Also:

• Map.entrySet()

keySet

public IntSet keySet()

Description copied from interface: Int2ByteMap

Specified by:

keySet in interface Int2ByteMap

Specified by:

keySet in interface Map<Integer,Byte>

Returns:

a set view of the keys contained in this map.

See Also:

• Map.keySet()

values

public ByteCollection values()

Description copied from interface: Int2ByteMap

Specified by:

values in interface Int2ByteMap

Specified by:

values in interface Map<Integer,Byte>

Returns:

a set view of the values contained in this map.

See Also:

• Map.values()

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<Integer,Byte>

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<Integer,Byte>

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Integer,Byte>

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
