Constructor and Description |
---|
ConcurrentSet()
Constructs a new, empty set; the backing ConcurrentHashMap instance has
default initial capacity (16) and load factor (0.75).
|
ConcurrentSet(Collection<? extends E> c)
Constructs a new set containing the elements in the specified
collection.
|
ConcurrentSet(int initialCapacity)
Constructs a new, empty set; the backing ConcurrentHashMap instance has
the specified initial capacity and default load factor, which is
0.75.
|
ConcurrentSet(int initialCapacity,
float loadFactor,
int concurrencyLevel)
Constructs a new, empty set; the backing ConcurrentHashMap instance has
the specified initial capacity and the specified load factor.

initialCapacity
- the initial capacity. The implementation
performs internal sizing to accommodate this many elements.loadFactor
- the load factor threshold, used to control resizing.
Resizing may be performed when the average number of elements per
bin exceeds this threshold.concurrencyLevel
- the estimated number of concurrently
updating threads. The implementation performs internal sizing
to try to accommodate this many threads.IllegalArgumentException
- if the initial capacity is less
than zero, or if the load factor is nonpositive.public ConcurrentSet(int initialCapacity)
initialCapacity
- the initial capacity of the hash table.IllegalArgumentException
- if the initial capacity is less
than zero.Copyright © 2018 JBoss by Red Hat. All rights reserved.
