    putAll in interface TObjectDoubleMap<K>
    
    Parameters:
    
    m - The map from which entries will be obtained to put into this map.
  - putAll
```
public void putAll(java.util.Map<? extends K,? extends java.lang.Double> map)
```
    Description copied from interface: TObjectDoubleMap
    
    Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.
    
    Specified by:
    
    putAll in interface TObjectDoubleMap<K>
    
    Parameters:
    
    map - mappings to be stored in this map
  - clear
```
public void clear()
```
    Description copied from interface: TObjectDoubleMap
    
    Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
    
    Specified by:
    
    clear in interface TObjectDoubleMap<K>
  - keySet
```
public java.util.Set<K> keySet()
```
    Description copied from interface: TObjectDoubleMap
    
    Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.
    
    Specified by:
    
    keySet in interface TObjectDoubleMap<K>
    
    Returns:
    
    a set view of the keys contained in this map
  - keys
```
public java.lang.Object[] keys()
```
    Description copied from interface: TObjectDoubleMap
    
    Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
    
    Specified by:
    
    keys in interface TObjectDoubleMap<K>
    
    Returns:
    
    a copy of the keys of the map as an array.
  - keys
```
public K[] keys(K[] array)
```
    Description copied from interface: TObjectDoubleMap
    
    Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
    
    Specified by:
    
    keys in interface TObjectDoubleMap<K>
    
    Parameters:
    
    array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.
    
    Returns:
    
    the keys of the map as an array.
  - valueCollection
```
public TDoubleCollection valueCollection()
```
    Description copied from interface: TObjectDoubleMap
    
    Returns a TDoubleCollection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the TDoubleIterator.remove, TDoubleCollection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
    
    Specified by:
    
    valueCollection in interface TObjectDoubleMap<K>
    
    Returns:
    
    a collection view of the values contained in this map
  - values
```
public double[] values()
```
    Description copied from interface: TObjectDoubleMap
    
    Returns the values of the map as an array of double values. Changes to the array of values will not be reflected in the map nor vice-versa.
    
    Specified by:
    
    values in interface TObjectDoubleMap<K>
    
    Returns:
    
    the values of the map as an array of double values.
  - values
```
public double[] values(double[] array)
```
    Description copied from interface: TObjectDoubleMap
    
    Returns the values of the map using an existing array. Changes to the array of values will not be reflected in the map nor vice-versa.
    
    Specified by:
    
    values in interface TObjectDoubleMap<K>
    
    Parameters:
    
    array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.
    
    Returns:
    
    the values of the map as an array of double values.
  - equals
```
public boolean equals(java.lang.Object o)
```
    Description copied from interface: TObjectDoubleMap
    
    Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.
    
    Specified by:
    
    equals in interface TObjectDoubleMap<K>
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    o - object to be compared for equality with this map
    
    Returns:
    
    true if the specified object is equal to this map
  - hashCode
```
public int hashCode()
```
    Description copied from interface: TObjectDoubleMap
    
    Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that m1.equals(m2) implies that m1.hashCode()==m2.hashCode() for any two maps m1 and m2, as required by the general contract of Object.hashCode().
    
    Specified by:
    
    hashCode in interface TObjectDoubleMap<K>
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    the hash code value for this map
    
    See Also:
    
    Object.equals(Object), TObjectDoubleMap.equals(Object)
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - getNoEntryValue
```
public double getNoEntryValue()
```
    Description copied from interface: TObjectDoubleMap
    
    Returns the value that will be returned from TObjectDoubleMap.get(java.lang.Object) or TObjectDoubleMap.put(K, double) if no entry exists for a given key. The default value is generally zero, but can be configured during construction of the collection.
    
    Specified by:
    
    getNoEntryValue in interface TObjectDoubleMap<K>
    
    Returns:
    
    the value that represents a null value in this collection.
