public SoftValueHashMap(int initialCapacity, float loadFactor)
WeakHashMap
with the given initial
capacity and the given load factor.
initialCapacity
- the initial capacity of the WeakHashMap
loadFactor
- the load factor of the WeakHashMap
IllegalArgumentException

or if the load factor is nonpositivepublic SoftValueHashMap(int initialCapacity)
WeakHashMap
with the given initial
capacity and the default load factor, which is 0.75
.
initialCapacity
- the initial capacity of the WeakHashMap
IllegalArgumentException
- if the initial capacity is less than zeropublic SoftValueHashMap()
WeakHashMap
with the default
initial capacity and the default load factor, which is 0.75
.
public SoftValueHashMap(Map<String,javassist.CtClass> t)
WeakHashMap
with the same mappings as the
specified Map. The WeakHashMap
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.
