Method Detail

containsValue

public boolean containsValue(double v)
Specified by:
containsValue in interface Short2DoubleMap
See Also:
Map.containsValue(Object)

containsValue

public boolean containsValue(java.lang.Object ov)
Specified by:
containsValue in interface java.util.Map<java.lang.Short,java.lang.Double>

putAll

public void putAll(java.util.Map<? extends java.lang.Short,? extends java.lang.Double> m)
Specified by:
putAll in interface java.util.Map<java.lang.Short,java.lang.Double>

short2DoubleEntrySet

public ObjectSet<Short2DoubleMap.Entry> short2DoubleEntrySet()
Description copied from interface: Short2DoubleMap
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 Short2DoubleMap.entrySet() so that it returns an ObjectSet of objects of type Short2DoubleMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:
short2DoubleEntrySet in interface Short2DoubleMap
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Short2DoubleMap.entrySet()

keySet

public ShortSet keySet()
Description copied from interface: Short2DoubleMap
Returns a set view of the keys contained in this map.

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

Specified by:
keySet in interface Short2DoubleMap
Specified by:
keySet in interface java.util.Map<java.lang.Short,java.lang.Double>
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

values

public DoubleCollection values()
Description copied from interface: Short2DoubleMap
Returns a set view of the values contained in this map.

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

Specified by:
values in interface Short2DoubleMap
Specified by:
values in interface java.util.Map<java.lang.Short,java.lang.Double>
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<java.lang.Short,java.lang.Double>

entrySet

public ObjectSet<java.util.Map.Entry<java.lang.Short,java.lang.Double>> entrySet()
Description copied from interface: Short2DoubleMap
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 Short2DoubleMap
Specified by:
entrySet in interface java.util.Map<java.lang.Short,java.lang.Double>
Returns:
a set view of the mappings contained in this map.
See Also:
Map.entrySet()

hashCode

public int hashCode()
Specified by:
hashCode in interface java.util.Map<java.lang.Short,java.lang.Double>
Overrides:
hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)
Specified by:
equals in interface java.util.Map<java.lang.Short,java.lang.Double>
Overrides:
equals in class java.lang.Object

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
