final public static double DEFAULT_LOAD_FACTOR(Code)
The default load factor of this map.




Constructor Detail
FloatKeyDoubleOpenHashMap
public FloatKeyDoubleOpenHashMap()(Code)
Creates a new hash map with capacity 11, a relative growth factor of 1.0, and a load factor of 75%.



FloatKeyDoubleOpenHashMap
public FloatKeyDoubleOpenHashMap(FloatKeyDoubleMap map)(Code)
Creates a new hash map with the same mappings as a specified map.
Parameters:
  map - the map whose mappings to put into the new map.
throws:
  NullPointerException - if map is null.



FloatKeyDoubleOpenHashMap
public FloatKeyDoubleOpenHashMap(int capacity)(Code)
Creates a new hash map with a specified capacity, a relative growth factor of 1.0, and a load factor of 75%.
Parameters:
  capacity - the initial capacity of the map.
throws:
  IllegalArgumentException - if capacity is negative.



FloatKeyDoubleOpenHashMap
public FloatKeyDoubleOpenHashMap(double loadFactor)(Code)
Creates a new hash map with a capacity of 11, a relative growth factor of 1.0, and a specified load factor.
Parameters:
  loadFactor - the load factor of the map.
throws:
  IllegalArgumentException - if capacity is negative;if loadFactor is not positive.



FloatKeyDoubleOpenHashMap
public FloatKeyDoubleOpenHashMap(int capacity, double loadFactor)(Code)
Creates a new hash map with a specified capacity and load factor, and a relative growth factor of 1.0.
Parameters:
  capacity - the initial capacity of the map.
Parameters:
  loadFactor - the load factor of the map.
throws:
  IllegalArgumentException - if capacity is negative;if loadFactor is not positive.



FloatKeyDoubleOpenHashMap
public FloatKeyDoubleOpenHashMap(int capacity, double loadFactor, double growthFactor)(Code)
Creates a new hash map with a specified capacity, load factor, and relative growth factor.

The map capacity increases to capacity()*(1+growthFactor). This strategy is good for avoiding many capacity increases, but the amount of wasted memory is approximately the size of the map.
Parameters:
  capacity - the initial capacity of the map.
Parameters:
  loadFactor - the load factor of the map.
Parameters:
  growthFactor - the relative amount with which to increase thethe capacity when a capacity increase is needed.
