Creates a new hash map with the same mappings as a specified map. | | public | CharKeyDoubleOpenHashMap(int capacity)
Creates a new hash map with a specified capacity, a relative
growth factor of 1.0, and a load factor of 75%. | | public | CharKeyDoubleOpenHashMap(double loadFactor)

growth factor of 1.0, and a specified load factor. | | public | CharKeyDoubleOpenHashMap(int capacity, double loadFactor)

| CharKeyDoubleOpenHashMap | | public CharKeyDoubleOpenHashMap()(Code) | | Creates a new hash map with capacity 11, a relative
growth factor of 1.0, and a load factor of 75%.
|
| CharKeyDoubleOpenHashMap | | public CharKeyDoubleOpenHashMap(CharKeyDoubleMap 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. |
| CharKeyDoubleOpenHashMap | | public CharKeyDoubleOpenHashMap(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. |
| CharKeyDoubleOpenHashMap | | public CharKeyDoubleOpenHashMap(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. |
| CharKeyDoubleOpenHashMap | | public CharKeyDoubleOpenHashMap(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. |
| CharKeyDoubleOpenHashMap | | public CharKeyDoubleOpenHashMap(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.
throws:
IllegalArgumentException - if capacity is negative;if loadFactor is not positive;if growthFactor is not positive. |
