Method Detail

containsValue
public boolean containsValue(double v)
Description copied from interface:Int2DoubleMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceInt2DoubleMap
- 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 interfaceInt2DoubleMap
- Specified by:
containsValue
in interfacejava.util.Map<java.lang.Integer,java.lang.Double>
-
putAll
public void putAll(java.util.Map<? extends java.lang.Integer,? extends java.lang.Double> m)
- Specified by:
putAll
in interfacejava.util.Map<java.lang.Integer,java.lang.Double>
-
int2DoubleEntrySet
public ObjectSet<Int2DoubleMap.Entry> int2DoubleEntrySet()
Description copied from interface:Int2DoubleMap
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 anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
int2DoubleEntrySet
in interfaceInt2DoubleMap
- 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.Integer,java.lang.Double>> 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 interfaceInt2DoubleMap
- Specified by:
entrySet
in interfacejava.util.Map<java.lang.Integer,java.lang.Double>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public IntSet keySet()
Description copied from interface:Int2DoubleMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceInt2DoubleMap
- Specified by:
keySet
in interfacejava.util.Map<java.lang.Integer,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:Int2DoubleMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceInt2DoubleMap
- Specified by:
values
in interfacejava.util.Map<java.lang.Integer,java.lang.Double>
- Returns:
- a set view of the values contained in this map.
- See Also:
