    Retrieves the value for key.
    
    Returns:
    
    the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).
  - put
```
double put(K key,
           double value)
```
    Inserts a key/value pair into the map.
    
    Returns:
    
    the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).

```
double putIfAbsent(K key,
                   double value)
```
    Inserts a key/value pair into the map if the specified key is not already associated with a value.

  - putAll
```
void putAll(java.util.Map<? extends K,? extends java.lang.Double> m)
```
    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.
    
    Parameters:
    
    m - mappings to be stored in this map
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the putAll operation is not supported by this map
    
    java.lang.ClassCastException - if the class of a key or value in the specified map prevents it from being stored in this map
    
    java.lang.NullPointerException - if the specified map is null, or if this map does not permit null keys or values, and the specified map contains null keys or values
    
    java.lang.IllegalArgumentException - if some property of a key or value in the specified map prevents it from being stored in this map
  - putAll
```
void putAll(TObjectDoubleMap<? extends K> map)
```
    Put all the entries from the given map into this map.
    
    Parameters:
    
    map - The map from which entries will be obtained to put into this map.
  - clear
```
void clear()
```
    Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the clear operation is not supported by this map
  - keySet
```
java.util.Set<K> keySet()
```
    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.
    
    Returns:
    
    a set view of the keys contained in this map
  - keys
```
java.lang.Object[] keys()
```
    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.
    
    Returns:
    
    a copy of the keys of the map as an array.
  - keys
```
K[] keys(K[] array)
```
    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.
    
    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
```
TDoubleCollection valueCollection()
```
    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.
    
    Returns:
    
    a collection view of the values contained in this map
  - values
```
double[] values()
```
    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.
    
    Returns:
    
    the values of the map as an array of double values.
  - values
```
double[] values(double[] array)
```
    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.
    
    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.

    the values of the map as an array of double values.
  - iterator
```
TObjectDoubleIterator<K> iterator()
```
    Returns a TObjectDoubleIterator with access to this map's keys and values.
    
    Returns:
    
    a TObjectDoubleIterator with access to this map's keys and values.
  - increment
```
boolean increment(K key)
```
    Increments the primitive value mapped to key by 1
    
    Parameters:
    
    key - the key of the value to increment
    
    Returns:
    
    true if a mapping was found and modified.
  - adjustValue
```
boolean adjustValue(K key,
                    double amount)
```
    Adds an amount to the primitive value mapped to key. If the key does not exist, the map is not modified (key-value is not inserted).
    
    Parameters:
    
    key - the key of the value to increment
    
    amount - the amount to add to the value; may be positive, zero, or negative

    adjustOrPutValue(Object, double, double)
  - adjustOrPutValue
```
double adjustOrPutValue(K key,
                        double adjust_amount,
                        double put_amount)
```
    Adds an amount to the primitive value mapped to the key if the key is present in the map. Otherwise, the put_amount is put in the map.
    
    Parameters:
    
    key - the key of the value to increment
    
    adjust_amount - the amount to add to the value; may be positive, zero, or negative
    
    put_amount - the value put into the map if the key is not present
    
    Returns:
    
    the value present in the map after the adjustment or put operation
  - forEachKey
```
boolean forEachKey(TObjectProcedure<? super K> procedure)
```
    Executes procedure for each key in the map.
    
    Parameters:
    
    procedure - a TObjectProcedure value
    
    Returns:
    
    false if the loop over the keys terminated because the procedure returned false for some key.
  - forEachValue
```
boolean forEachValue(TDoubleProcedure procedure)
```
    Executes procedure for each value in the map.
    
    Parameters:
    
    procedure - a TDoubleProcedure value
    
    Returns:
    
    false if the loop over the values terminated because the procedure returned false for some value.
  - forEachEntry
```
boolean forEachEntry(TObjectDoubleProcedure<? super K> procedure)
```
    Executes procedure for each key/value entry in the map.
    
    Parameters:
    
    procedure - a TOObjectDoubleProcedure value
    
    Returns:
    
    false if the loop over the entries terminated because the procedure returned false for some entry.
  - transformValues
```
void transformValues(TDoubleFunction function)
```
    Transform the values in this map using function.
    
    Parameters:
    
    function - a TDoubleFunction value
  - retainEntries
```
boolean retainEntries(TObjectDoubleProcedure<? super K> procedure)
```
    Retains only those entries in the map for which the procedure returns a true value.
    
    Parameters:
    
    procedure - determines which entries to keep
    
    Returns:
    
    true if the map was modified.
  - equals
```
boolean equals(java.lang.Object o)
```
    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.
    
    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
```
int hashCode()
```
    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().
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    the hash code value for this map
    
    See Also:
    
    Object.equals(Object), equals(Object)
