- Constructor Detail
  - DoubleToIntMap
```
public DoubleToIntMap()
```
    Constructs a new empty map with a default capacity of 11.
  - DoubleToIntMap
```
public DoubleToIntMap(int initialCapacity)
```
    Constructs a new empty map with the specified initial capacity and a default load factor equal to 0.75.
    
    Parameters:
    initialCapacity - the initial capacity of the map
    
    Throws:
    
    java.lang.IllegalArgumentException - if the initial capacity is negative.
  - DoubleToIntMap
```
public DoubleToIntMap(int initialCapacity,
              float loadFactor)
```
    Constructs a new empty map with the specified initial capacity and load factor. If the load factor is greater than 1, it is reset to 1 (which means that the map is enlarged only when all the table's indices are occupied - generally a bad idea).
    
    Parameters:
    initialCapacity - the initial capacity of the map
    loadFactor - the load factor of the map
    
    Throws:
    
    java.lang.IllegalArgumentException - if either argument is negative.
  - DoubleToIntMap
```
public DoubleToIntMap(DoubleToIntMap map)
```
    Constructs a new map with the same entries as the given map. The map is created with a capacity of twice the number of entries in the given map or 11 (whichever is greater), and a default load factor, which is 0.75.
    
    Parameters:
    map - the DoubleToIntMap whose entries are to be placed in this map.
- Method Detail
  - containsKey
```
public final boolean containsKey(double key)
```
    Returns true if this map contains an entry for the specified key.
    
    Parameters:
    key - the key whose presence in this map is to be tested.
  - containsEntry
```
public final boolean containsEntry(double key,
                    int value)
```
    Returns true if this map contains an entry with the specified key and value.
    
    Parameters:
    key - the key
    value - the value
  - containsEntry
```
public final boolean containsEntry(ToIntMap.Entry candidate)
```
    Returns true if this map contains the specified entry.
    
    Specified by:
    
    containsEntry in class ToIntMap
    
    Parameters:
    candidate - the entry whose presence in this map is to be tested.
  - get
```
public final int get(double key)
```
    Returns the value to which this map maps the specified key. Returns NOT_FOUND_VALUE if the map contains no entry for this key. The value NOT_FOUND_VALUE is defined as Integer.MIN_VALUE (which is equal to -2147483648). Therefore, a return value equal to NOT_FOUND_VALUE does not necessarily indicate that the map contains no entry for the key; it's also possible that the map explicitly maps the key to -2147483648. In this case, the containsKey operation may be used to distinguish these two cases.
    
    Parameters:
    key - the key whose associated value is to be returned.
  - add
```
public final int add(double x)
```
    Associates the current size of the map to the given double, and returns this value.
  - put
```
public final int put(double key,
      int value)
```
    Associates the specified value with the specified key in this map. If the map previously contained an entry for this key, the old value is replaced and returned; otherwise the new value is returned. The map is automatically enlarged if its size exceeds its threshold.
    
    Parameters:
    key - key with which the specified value is to be associated.
    value - value to be associated with the specified key.
  - remove
```
public final int remove(double key)
```
    Removes the entry for the given key from this map if present. Returns the previous value associated with the specified key, or NOT_FOUND_VALUE if there was no entry for the key. A returned NOT_FOUND_VALUE may also indicate that the map previously associated NOT_FOUND_VALUE with the specified key.
    
    Parameters:
    key - key whose entry is to be removed from the map.
  - put
```
public final int put(ToIntMap.Entry entry)
```
    Puts the mapping defined by the specified entry into this map. Returns the old value if one was there, or the new value.
    
    Specified by:
    
    put in class ToIntMap
    
    Parameters:
    entry - the entry whose mapping is to be put into this map.
  - keys
```
public final DoubleIterator keys()
```
    Returns an iterator through the keys of this map. The value returned by its next() method is a double.
  - values
```
public final IntIterator values()
```
    Returns an iterator through the values of this map. The value returned by its next() method is an int.
    
    Specified by:
    
    values in class ToIntMap
  - equals
```
public final boolean equals(java.lang.Object object)
```
    Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps have equal entries.
    
    Overrides:
    
    equals in class ToIntMap
    
    Parameters:
    object - object to be compared for equality with this map.
