Method Detail

containsValue

public boolean containsValue(boolean v)

Description copied from interface: Byte2BooleanMap

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

Specified by:

containsValue in interface Byte2BooleanMap

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 Byte2BooleanMap

Specified by:

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

putAll

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

Specified by:

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

byte2BooleanEntrySet

public ObjectSet<Byte2BooleanMap.Entry> byte2BooleanEntrySet()

Description copied from interface: Byte2BooleanMap

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:

byte2BooleanEntrySet in interface Byte2BooleanMap

Returns:

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

See Also:

Map.entrySet()

keySet

public ByteSet keySet()

Description copied from interface: Byte2BooleanMap

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

Specified by:

keySet in interface Byte2BooleanMap

Specified by:

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

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public BooleanCollection values()

Description copied from interface: Byte2BooleanMap

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

Specified by:

values in interface Byte2BooleanMap

Specified by:

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

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

clone

public java.lang.Object clone()

Overrides:

clone in class Byte2BooleanFunctions.EmptyFunction

isEmpty

public boolean isEmpty()

Specified by:

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

hashCode

public int hashCode()

Specified by:

hashCode in interface java.util.Map<java.lang.Byte,java.lang.Boolean>

Overrides:

hashCode in class Byte2BooleanFunctions.EmptyFunction

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.util.Map<java.lang.Byte,java.lang.Boolean>

Overrides:

equals in class Byte2BooleanFunctions.EmptyFunction

toString

public java.lang.String toString()

Overrides:

toString in class Byte2BooleanFunctions.EmptyFunction
