SoftValueHashMap
public SoftValueHashMap(int initialCapacity,
float loadFactor)
- Constructs a new, empty
SoftValueHashMap
with the given
initial capacity and the given load factor.
- Parameters:
initialCapacity
- The initial capacity of the
SoftValueHashMap
loadFactor
- The load factor of the SoftValueHashMap
- Throws:
IllegalArgumentException
- If the initial capacity is less than
zero, or if the load factor is
nonpositive
SoftValueHashMap
public SoftValueHashMap(int initialCapacity)
- Constructs a new, empty
SoftValueHashMap
with the given
initial capacity and the default load factor, which is
0.75
.
- Parameters:
initialCapacity
- The initial capacity of the
SoftValueHashMap
- Throws:
IllegalArgumentException
- If the initial capacity is less than
zero
SoftValueHashMap
public SoftValueHashMap()
- Constructs a new, empty
SoftValueHashMap
with the default
initial capacity and the default load factor, which is
0.75
.
SoftValueHashMap
public SoftValueHashMap(Map<K,V> t)
- Constructs a new
SoftValueHashMap
with the same mappings as the
specified Map. The SoftValueHashMap
is created with an
initial capacity of twice the number of mappings in the specified map
or 11 (whichever is greater), and a default load factor, which is
0.75.
- Parameters:
t
- the map whose mappings are to be placed in this map.- Since:
